PQxxxY3H3Z Series/PQxxxY053Z Series www..com s Precautions for Use VIN 1 2 VO CIN 5 3 4 VO (sense) CO + Load C-MOS or TTL 1. External connection (1) The connecting wiring of CO and each terminal must be as short as possible. Owing to type, value and wiring condition of capacitor, it may oscillate. Confirm the output waveform under the actual condition before using. (2) ON/OFF control terminal 5 is compatible with LS-TTL. It enables to be directly drive by TTL or C-MOS standard logic (RCA4000 series). Please make sure to use this device, pulling up to the power supply with less than 7V at the resistor less than 50k in switching ON/OFF with open collector output or in not using ON/OFF function (in keeping "ON"), because input impedance is high in ON/OFF terminals. (3) If voltage is applied under the conditions that the device pin is connected divergently or reversely, the deterioration of characteristics or damage may occur. Never allow improper mounting. (4) If voltage exceeding the voltage of DC input terminal 1 is applied to the output terminal 2 , the element may be damaged. Especially when the DC input terminal 1 is short-circuited to the GND in ordinary operating state, charges accumulated in the output capacitor CO flow to the input side, causing damage to the element. In this case, connect the ordinary silicon diode as shown in the figure. 2. Thermal protection design Maximum power dissipation of devices is obtained by the following equation. PD=IOx(VIN-VO)+VINxIq When ambient temperature Ta and power dissipation PD (MAX.) during operation are determined, operate element within the safety operation area specified by the derating curve. Insufficient radiation gives an unfavorable influence to the normal operation and reliability of the device. In the external area of the safety operation area shown by the derating curve, the overheat protection circuit may operate to shutdown output. However please avoid keeping such condition for a long time. 3. ESD (Electrostatic Sensitivity Discharge) Be careful not to apply electrostatic discharge to the device since this device employs a bipolar IC and may be damaged by electro static discharge. Followings are some methods against excessive voltage caused by electro static discharge. (1) Human body must be grounded to discharge the electro charge which is charged in the body or cloth. (2) Anything that is in contact with the device such as workbench, inserter, or measuring instrument must be grounded. (3) Use a soldering dip basin with a minimum leak current (isolation resistance 10M or more) from the AC power supply line. Also the soldering dip basin must be grounded. 1 2 Application Circuits www..com NOTICE qThe circuit application examples in this publication are provided to explain representative applications of SHARP devices and are not intended to guarantee any circuit design or license any intellectual property rights.
