The STGAP4S galvanically remoted automotive gate driver from ST connects to an exterior MOSFET-based push-pull buffer to scale gate present functionality. This structure allows management of inverters with various energy scores, together with high-power designs with a number of parallel energy switches.
The STGAP4S can ship gate drive currents within the tens of amperes utilizing small exterior MOSFETs and handles working voltages as much as 1200 V. It integrates an ADC, a flyback controller, programmable protections, and complete diagnostics. The system is AEC-Q100 and ISO 26262 certified, supporting system designs as much as ASIL D.
Superior diagnostics within the STGAP4S embody self-checks for connections, gate-drive voltages, and inside circuitry corresponding to desaturation and overcurrent detection. Faults are reported through SPI and two diagnostic pins. Protections like lively Miller clamping, UVLO, OVLO, desaturation, overcurrent, and over-temperature detection guarantee sturdy designs. Configurable thresholds, deadtime, and deglitch filters—programmable by way of SPI—allow flexibility whereas assembly ISO 26262 as much as ASIL D.
Now in manufacturing, the STGAP4S is on the market in a SO-36W wide-body DIP, priced from $4.66 every in plenty of 1000 models.
