STMicroelectronics Products STGAP2S and STGAP2D gate drivers

The gate driver is characterized by 4 A capability and rail-to-rail outputs, suitable also for high power inverter applications (motor drivers in industrial applications).

STGAP2S is available in two different configurations. The configuration with separated output pins allows optimizing turn-on and turn-off times independently, by using dedicated gate resistors.

STGAP2D integrates several protection functions: dedicated SD and BRAKE pins are available, UVLO and thermal shutdown, and the interlocking function that prevents outputs from being high at the same time.
