TLP5752H(D4TP4,E

Isolators - Gate Drivers Overview

The TLP5752H(D4TP4,E is a one-channel optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED with a high-gain, high-speed photodetector IC to provide robust signal isolation for power switching applications. The device features a push-pull output stage capable of sourcing and sinking 2.5A peak current. Key electrical parameters include a maximum propagation delay of 150ns for both rising and falling edges, with typical rise and fall times of 15ns and 8ns respectively. It offers a minimum common-mode transient immunity (CMTI) of 35kV/µs and supports an isolation voltage of 5000Vrms. The component operates within a temperature range of -40°C to +125°C and is housed in a compact 6-SO package.
