Description

Technical Parameters

The ACPL-W345-500E optocoupler gate driver presents a formidable solution with its impressive 1.0A maximum peak output current, 0.8A minimum peak output current, and rail-to-rail output voltage. Its exceptional speed is evident in the 120 ns maximum propagation delay and 50 ns maximum propagation delay difference, ensuring rapid and symmetrical signal transmission. The device incorporates LED current input with hysteresis for enhanced stability and reliability. Notably, its robust 100 kV/µs minimum Common Mode Rejection at VCM = 1500V enhances immunity to common mode noise. With a maximum supply current of 4.0 mA and Under Voltage Lock-Out protection with hysteresis, the ACPL-W345-500E strikes a balance between efficiency and reliability. Its wide operating VCC range (10V to 20V) and industrial temperature range (-40°C to +105°C) make it a versatile choice for applications requiring precision and performance in challenging conditions.

Description:

The Broadcom® 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, GaN(Gallium Nitride), and SiC(Silicon Carbide) MOSFETs used in inverter or AC-DC/DC-DC converter applications. The high operating 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 optocoupler 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 = 891 Vpeak and VIORM = 1140 Vpeak respectively in the IEC/EN/DIN EN 60747-5-5.
