epc700/epc702 24v/50ma general-purpose output-driver general description the epc70x family is a general purpose low-side power switch for 24v interfaces. a high-side switch is also available, please refer to the separate data sheet of epc701/703. the device is very easy to use and capable to drive a load of 50ma at 30vdc. if a higher driving current is necessary or if the output voltage shall be higher than 30vdc, these chips can be used to drive an external power transistor. in this mode of operation, the external tran sistor is fully protected against over-current by the epc chip. if the current through the external load exceeds a specified threshold during a longer time period than a predefined time, the output is turned off to protect the output switch. the switch is turned on again after a predefined off-time, thus enabling the load again in a self-healing mechanism. the over-current information is indicated on the status pin. epc700 and epc702 are easy to use and reduce the need of ex - ternal components to the minimum, thus saving pcb space and money. features ? low-side power switch ? driving capability without external transistor 50 ma/30vdc ? programmable short-circuit detection delay-time and recovery time ? static (epc700) or flashing (epc702) indication of the over-current status ? self-healing output mode ? available in csp6 package with very small footprint and standard qfn16 package applications ? plc ? sensors ? controllers functional block diagram 25.05.2011 page 1 file: unbenannt this document is confidential and protected by law and international trades. it must not be shown to any third party nor be copied in any form without our written permission . functional block diagram epc70x lst in status gnd control logic configuration registers i sink i source out sense r sense over current sense + C + ref vdd over-current delay / release gnd gnd gnd gnd ? 2011 espros photonics corporation characteristics subject to change without notice 1 datasheet epc700_702 - v2.2 www.espros.ch

epc700/epc702 functional description normal operation during typical operation the out follows the in as shown in figure 1 . as long as the output current does not exceed the current threshold, out is stable on and status is stable high-z. the delay from in to out is defined as t on and t off for the rising and the falling edge respectively. please note that the status of the pin out is dependent whether the chip is operated with or without external driver transistor. in the subsequent diagrams, the version with external driver transistor is shown only. over-current sequence a short on the load side will lead to an over-current through out. if an over-current stays longer than the time t del and t ext , out is turned off as shown in the figure below. at the same time status changes its state to indicate an over-current situation to an external controller. status can also be used to drive directly an indicator led due to its 10ma driving capability. epc700 delivers a constant on-signal, whereas epc702 has a flashing output. note: the parameter t ext used in this paper is described in figure 7 . ? 2011 espros photonics corporation characteristics subject to change without notice 4 datasheet epc700_702 - v2.2 www.espros.ch figure 1 : normal operation timing diagram operation mode epc700 lst in out (without external transistor) status epc700 short sens high-z 05.01.2011 page 1 file: this document is confidential and protected by law and international trades. it must not be shown to any third party nor be copied in any form without our written permission . 05.01.2011 page 1 file: this document is confidential and protected by law and international trades. it must not be shown to any third party nor be copied in any form without our written permission . t led t led t led t led t led t led t led t led status epc702 0 0 high-z 0 v th sens high-z t off t on out (with external transistor) v sat vdd v sat figure 2 : short circuit detection timing diagram typical overcurrent epc700 lst v th sens t del t ext in out status epc700 short sens high-z 04.08.2010 page 1 file: this document is confidential and protected by law and international trades. it must not be shown to any third party nor be copied in any form without our written permission . status epc702 0 0 0 0 t led high-z
epc700/epc702 current peak at out a short current peak when out is turned on, typically generated by a capacitive load, could trigger the short-circuit protection logic. however, if the current peak is shorter than t ext plus t del , the over-current peak will be ignored. make sure that the energy drawn by such a current peak does not destroy the internal/external output transistor. over-current reset sequence if there is a permanent short circuit at out, such short circuit will be detected and out is turned off. after a waiting time t minoff , the device tries to turn on out again. if the short circuit is still present, out is immediately turned off again. this sequence continues until the short circuit is removed or in goes to low or power is turned off. this mode is called self-healing since the device tries to self-heal the short circuit end to switch back into normal operation. as a consequence in the case of a permanent over-current , short current peaks are issued into the load, respectively short. the time t minoff has to be set to a value that the internal/external switch cannot be damaged by a too high power dissipation. without an exter - nal switch, the time t minoff has to be 1,000 times longer than the time t del . if one wants to reduce the waiting time in case of a short circuit situation, it can be done by simply taking in to a low state and then to high again. please refer to the timing diagram in figure 5 . however, make sure that the maximum power dissipation of the chip or the external switching transistor will never be exceeded above the allowed maximum. ?

epc700/epc702 programming the time delay (t del ), until the output is turned off after the detection of an over-current condition can be programmed in order to adapt the ti - ming to specific requirements, i.e., if a capacitive load has to be operated or an external transistor allows other values. the default value is 50s which allows to charge a load capacitor of approx. 100 C 500nf without an external power transistor, dependent on the source impe - dance, the load impedance and the voltage v l . the time until the output is turned on again after a short circuit can be programmed as well (t minoff ). this self-healing mechanism is very use - ful because no operator interaction is necessary after a short circuit to enable normal function once the short circuit has been eliminated. the default value is 500ms which means that the device tries to turn the output on after 0.5s waiting time in the short circuit mode. this waiting time is recommended as long as t del is not changed. if t del has been changed, the parameter t minoff shall be changed accordingly in order to respect parameter f rt . the user has to ensure that the maximum operation conditions never exceed in order to avoid damage of the device. it is to note that the parameters programmed are stored in a non-volatile random access memory. thus, the parameters can be lost after a power down for longer than 5ms (data retention time @ 25 o c: min. 100ms ). the corresponding requirements for safety applications have to take in consideration. parameters can be changed as many times as necessary and even under operation to change the behavior of an output. during power-on, the default values are restored automatically. programming interface the interface to store changed parameters are the pins in and status. in is the chip select pin and status, which is under normal opera - tion an output, is used as an input pin. as long as the in pin is at low state, parameters can be stored through the status pin. since in is low during the programming of new parameters, out is low as well. the digital input high threshold is typically at 2.2v, thus a 5v compatible communication. please note that the voltage at status should not exceed 5.5v. single wire communication interface the epc70x is based on a single wire communication interface by using the status pin . programming is done by a 21-bit manchester code accor ding to ieee 802.4. clock (internal) 1 0 0 1 1 0 0 data manchester code figure 8 : m anchester encoding sample figure 8 shows such a sample m anchester encoded data-stream. the clock and the corresponding data is used to generate the m anchester data-stream. each positive clock - edge in the m anchester encoded data (indicated with the up - arrow) corresponds to a 1 and each negative clock - edge (indicated with the down - arrow) corresponds to a 0. data clock frequency range the communication frequency range has to be according to table 1 . minimal typical maximum data clock 396khz 450khz 540khz table 1 : frequency range for programming configuration bit stream for changing the delay time in order to guarantee a reliable communication with the manchester encoded bit stream on status, some additional bits have been added to the configuration bits. table 2 shows the digital pattern for the delay time configuration and the recovery time configuration. bit # 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 t del value 1 0 1 1 0 0 0 0 0 1 1 1 1 0 d1 d2 d3 1 d1 d2 d3 t minoff value 1 0 1 1 0 0 0 0 1 0 0 0 1 0 o1 o2 o3 1 o1 o2 o3 table 2 : configuration of the delay and the recovery time ? 2011 espros photonics corporation characteristics subject to change without notice 7 datasheet epc700_702 - v2.2 www.espros.ch
