STMicroelectronics STGAP2HDMTR, 4 A, 3.1 V, 5.5 V 36-Pin, SO-36W

The STMicroelectronics STGAP2HD is a dual gate driver which provides galvanic isolation between each gate driving channel and the low voltage control and interface circuitry. The gate driver is characterized by 4 A current capability and rail-to-rail outputs, making it suitable for mid and high power applications such as power conversion and industrial motor driver inverters. The separated output pins allow to independently optimize turn-on and turn-off by using dedicated gate resistors, while the Miller CLAMP function allows avoiding gate spikes during fast commutations in half-bridge topologies. The device integrates protection functions: dedicated SD and BRAKE pins are available, UVLO and thermal shutdown are included to easily design high reliability systems.

In half-bridge topologies the interlocking function prevents outputs from being high at the same time, avoiding shoot-through conditions in case of wrong logic input commands. The interlocking function can be disabled by a dedicated configuration pin, so to allow independent and parallel operation of the two channels. The input to output propagation delay results are contained within 75 ns, providing high PWM control accuracy. A standby mode is available in order to reduce idle power consumption.
