motorola analog integrated circuit device data 17511a 9 system/application information introduction the 17511a is a monolithic h-bridge power ic applicable to small dc motors used in portable electronics. the 17511a can operate efficiently with supply voltages as low as 2.0 v to as high as 6.8 v, and it can provid e continuos motor drive currents of 1.0 a while handling peak currents up to 3.0 a. it is easily interfaced to low-cost mcus via parallel 3.0 v- or 5.0 v- compatible logic. the device can be pulse width modulated (pwm-ed) at up to 200 khz. the 17511a has four operating modes: forward, reverse, br ake, and tri-stated (high impedance). basic protection and operationa l features (direction, dynamic braking, pwm control of speed and torque, main power supply undervoltage detection and shutdown, logic power supply undervoltage detection and shutdown), in addition to the 1.0 a rms output current capability, make the 17511a a very attractive, cost-effective solution for controlling a broad range of small dc motors. in addition, a pair of 17511a devices can be used to control bipolar step motors. the 17511a can also be used to excite transformer pr imary windings with a switched square wave to produce secondary winding ac currents. as shown in figure 1, 17511a simplified internal block diagram , page 2, the 17511a is a monolithic h-bridge with built-in charge pump circuitry. for a dc motor to run, the input conditions need to be set as fo llows: enable input logic high, one input logic low, and the ot her input logic high (to define output polarity). the 17511a can execute dynamic braking by setting both in1 and in2 logic high, causing both low-side mosfets in the output h-bridge to turn on. dynamic braking can also implemented by taking the enable logic low. the output of the h-bridge can be set to an open-circuit high- impedance (z) condition by taking both in1 and in2 logic low. (refer to table 1, truth table , page 8). the 17511a outputs are capabl e of providing a continuous dc load current of up to 1.2 a. an internal charge pump supports pwm frequencies to 200 khz. the en terminal also controls the charge pump, turning it off when en = low, thus allowing the 17511a to be placed in a power-conserving sleep mode. functional terminal description out1 and out2 the out1 and out2 terminals provide the connection to the internal power mosfet h-bridge of the ic. a typical load connected between these terminals would be a small dc motor. these outputs will connect to either vm or pgnd, depending on the states of the control inputs (refer to table 1, truth table , page 8). pgnd and lgnd the power and logic ground terminals (pgnd and lgnd) should be connected together with a very low-impedance connection. c res the c res terminal provides the connection for the external reservoir capacitor (o utput of the charge pump). alternatively this terminal can also be used as an input to supply gate-drive voltage from an external source via a series current-limiting resistor. the voltage at the c res terminal will be approximately three times the v dd voltage, as the internal charge pump utilizes a voltage tripler circuit. the v c res voltage is used by the ic to supply gate drive for the internal power mosfet h-bridge. vm the vm terminals carry the main supply voltage and current into the power sections of t he ic. this supply then becomes controlled and/or modulated by the ic as it delivers the power to the load attached between out1 and out2. all vm terminals must be connected together on the printed circuit board with as short as possible traces offering as low impedance as possible between terminals. vm has an undervoltage threshold. if the supply voltage drops below the undervoltage threshold, the output power stage switches to a tri-state cond ition. when the supply voltage returns to a level that is abov e the threshold, the power stage automatically resumes normal operation according to the established condition of the input terminals. in1, in2, and en the in1, in2, and en terminal s are input control terminals used to control the outputs. these terminals are 5.0 v cmos- compatible inputs with hysteresis. the in1, in2, and en work together to control out1 and out2 (refer to table 1, truth table ). gin the gin input controls the gout terminal. when gin is set logic low, gout supplies a leve l-shifted high-side gate drive signal to an external mosfet. when gin is set logic high, gout is set to gnd potential. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
