Overview
The STGAP1ASTR is a galvanically isolated single gate driver designed by STMicroelectronics for N-channel MOSFETs and IGBTs. This device features advanced protection, configuration, and diagnostic capabilities, making it suitable for high-power inverter applications. The architecture of the STGAP1ASTR ensures true galvanic isolation between the gate-driving channel and the low-voltage control and interface circuitry. It is characterized by a 2.5 A sink/source current capability at 25 °C and supports high voltage rails up to 2500 Vrms. The device is particularly useful in applications requiring high reliability and precision, such as motor drivers in hybrid and electric vehicles, industrial drives, and various power conversion systems.
