Photocouplers Infrared LED & Photo IC TLP5231
1. Applications
• IGBT Gate Drivers • MOSFET Gate Drivers • Industrial Inverters • AC Servos • Photovoltaic (PV) Power Conditioning Systems • Air Conditioner Inverters 2. General
The TLP5231 is a 2.5 A dual-output IGBT gate pre-drive photocoupler including highly integrated multi-functional
IC that is housed in SO16L package having a long creepage and clearance. This photocoupler is suitable as a predriver to driver power devices via external p-and n-channel MOSFET as buffers.
The smart gate driver photocoupler includes functions of IGBT/power MOSFET desaturation detection, isolated
fault status feedback, configurable soft gate turn-off, and under voltage lockout (UVLO).
The TLP5231 consists of two infrared light-emitting diodes (LEDs) and two high-gain and high-speed lightreceiving IC chips. Thereby, they realize the control of output current and the feedback function of the fault signal
while keeping a insulation between a primary side and secondary side electrically. 3. Features
