The STGAP2SCM is equipped with an active Miller clamp dedicated pin that provides a simple solution for designers to prevent accidental turn-on of the half-bridge configuration. This pin limits the gate voltage of the connected MOSFET when the MOSFET is turned off. Isolate the ground voltage until the next true turn-on signal appears.
The STGAP2SM has an independent on/off output that can be used with two external gate resistors to optimize transistor switching performance.
STGAP2S gate driver is equipped with standard 4A rail-to-rail output. Even if driving high-power inverter, it can ensure fast and efficient switching operation. Input-to-output propagation delay is within 80ns, ensuring accurate PWM control at high switching frequency. Meets the drive requirements of SiC devices. Excellent resistance to dV / dt common mode transients, enabling it to prevent energy-intensive stray switching operations.
These devices feature 1700V electrical isolation to reduce consumer or industrial motor drives, 600V or 1200V drives, DC/DC converters, chargers, welders, induction furnaces, uninterruptible power supplies (UPS) and power factor correction (PFC) The material cost of the controller.
These products incorporate comprehensive protection features, where undervoltage lockout (UVLO) protects the power switch when the supply voltage is too low. In addition, overtemperature protection and hardware interlocks prevent high-side/low-side cross conduction in half-bridge circuits The standby mode keeps the output in a safe state while conserving power.
The EVALSTGAP2SCM evaluation board provides a quick and easy development method that allows designers to quickly start designing.
The STGAP2SCM is available now, and the STGAP2SM is available in the fourth quarter of 2018 in a compact, industry-standard SO-8 power package.
