1 / 15 page ACPL-P345 and ACPL-W345 1.0 Amp Output Current Power & SiC MOSFET Gate Drive Optocoupler with Rail-to-Rail Output Voltage in Stretched SO6 Data Sheet CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD. Truth Table LED VCC – VEE “POSITIVE GOING” (i.e., TURN-ON) VCC – VEE “NEGATIVE GOING” (i.e., TURN-OFF) VO OFF 0 - 20 V 0 – 20 V LOW ON 0 – 8.1 V 0 – 7.1 V LOW ON 8.1 – 9.1 V 7.1 – 8.1 V TRANSITION ON 9.1 – 20V 8.1 – 20 V HIGH Description The ACPL-P345/W345 contains an AlGaAs LED, which is optically coupled to an integrated circuit with a power output stage. This optocoupler is ideally suited for driving power and SiC(Silicon Carbide) MOSFETs used in inverter or AC-DC/DC-DC converter applications. The high operat- ing voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and high peak output current supplied by this optocou- pler make it ideally suited for direct driving MOSFETs at high frequency for high efficiency conversion. The ACPL- P345 and ACPL-W345 have the highest insulation voltage of VIORM= 891Vpeak and VIORM= 1140Vpeak respectively in the IEC/ EN/DIN EN 60747-5-5. Functional Diagram Features • 1.0 A maximum peak output current • 0.8 A minimum peak output current • Rail-to-rail output voltage • 120 ns maximum propagation delay • 50 ns maximum propagation delay difference • LED current input with hysteresis • 50 kV/µs minimum Common Mode Rejection (CMR) at VCM = 1500 V • ICC = 4.0 mA maximum supply current • Under Voltage Lock-Out protection (UVLO) with hysteresis • Wide operating VCC Range: 10 to 20 V • Industrial temperature range: -40 °C to 105 °C • Safety Approval - UL Recognized 3750/5000 VRMS for 1min. - CSA - IEC/EN/DIN EN 60747-5-5 VIORM = 891/1140 Vpeak Applications • Power and SiC MOSFET gate drive • AC and Brushless DC motor drives • Switching power supplies VCC VOUT VEE 1 2 3 6 5 4 CATHODE NC ANODE Note: A 1 µF bypass capacitor must be connected between pins VCC and VEE. |
