Overview
The STGAP1BS (also available as STGAP1BSTR) is a galvanically isolated single gate driver designed for N-channel MOSFETs and IGBTs. It is produced by STMicroelectronics and features advanced protection, configuration, and diagnostic capabilities. The device is characterized by its true galvanic isolation between the channel and the control and low voltage interface circuitry. It is particularly suited for high power inverter applications, such as motor drivers in hybrid and electric vehicles, as well as industrial drives. The gate driver has a 5 A current capability and supports rail-to-rail output with the option for a negative gate driver supply. The input to output propagation delay is below 100 ns, ensuring high PWM control accuracy.
