TLP5231(TP,E
Description
Technical Parameters
The TLP5231 is a high-performance gate driver for optocouplers in power electronics, featuring a maximum output peak current of ±2.5 A, an operating temperature range of -40 to 110℃, and a low threshold input current of 3.5 mA. With a fast propagation delay time of 300 ns and a minimum common-mode transient immunity of ±25 kV/μs, it ensures efficient and responsive gate control in diverse applications. The device provides a high isolation voltage of 5000 Vrms, ensuring electrical separation, and includes dual output drive for external complementary type MOS buffers, offering flexibility in MOSFET configurations. Additionally, the TLP5231 incorporates Under Voltage Lock-Out protection for both positive and negative gate power supplies, enhancing reliability and safety in power electronics applications such as motor drives, inverters, and power converters.

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.
