STGAP1AS Automotive galvanically isolated advanced single gate driver Datasheet - production data Applications 600/1200 V inverters Inverters for EV HEV EV charging stations SO24W Industrial drives UPS equipment DC/DC converters Features Solar inverters Qualified for automotive applications according to AEC-Q100 Description High voltage rail up to 1500 V The STGAP1AS is a galvanically isolated single Driver current capability: 5 A sink/source gate driver for N-channel MOSFETs and IGBTs current at 25 C with advanced protection, configuration and dV/dt transient immunity 50 V/ns in full diagnostic features. The architecture of the temperature range STGAP1AS isolates the channel from the control and the low voltage interface circuitry through true Overall input/output propagation delay: 100 ns galvanic isolation. The gate driver is Separate sink and source for easy gate driving characterized by 5 A capability, making the device configuration also suitable for high power inverter applications Negative gate drive ability such as motor drivers in hybrid and electric vehicles and in industrial drives. The output driver Active Miller clamp section provides a rail-to-rail output with the Desaturation detection possibility to use a negative gate driver supply. SENSE input The input to output propagation delay results contained within 100 ns, providing high PWM V active clamping CE control accuracy. Protection functions such as the Output 2-level turn-off Miller clamp, desaturation detection, dedicated Diagnostic status output sense pin for overcurrent detection, output 2-level turn-off, VCE overvoltage protection, UVLO and UVLO and OVLO functions OVLO are included to easily design high reliability Programmable input deglitch filter systems. Open drain diagnostic outputs are Asynchronous stop command present and detailed device conditions can be monitored through the SPI. Each function s Programmable deadtime, with violation error parameter can be programmed via the SPI, SPI interface for parameters programming making the device very flexible and allowing it to Temperature warning and shutdown protection fit in a wide range of applications. Separate sink and source outputs provide high flexibility and bill Self-diagnostic routines for protection features of material reduction for external components.
