STGAP2D Galvanically isolated 4 A half-bridge gate driver Datasheet - production data Description The STGAP2D is a half-bridge gate driver which isolates the gate driving channels from the low voltage control and interface circuitry. The gate driver is characterized by 4 A capability and rail-to-rail outputs, making the device also SO-16 suitable for high power inverter applications such as motor drivers in industrial applications. Features The device integrates protection functions: dedicated SD and BRAKE pins are available, 1700 V dual channel gate driver UVLO and thermal shutdown are included to Driver current capability: 4 A sink / source at easily design high reliability systems, and the 25 C interlocking function prevents outputs from being high at the same time. dV/dt transient immunity 100 V/ns The input to output propagation delay results are Overall input-output propagation delay: 80 ns contained within 80 ns, providing high PWM UVLO function control accuracy. Interlocking function A standby mode is available in order to reduce Dedicated SD and BRAKE pins idle power consumption. Gate driving voltage up to 26 V 3.3 V, 5 V TTL/CMOS inputs with hysteresis Temperature shutdown protection Standby function Applications Motor driver for industrial drives, factory automation, home appliances and fans. 600/1200 V inverters Battery chargers Induction heating Welding UPS Power supply units DC-DC converters Power Factor Correction DS12746 Rev 1 1/21 This is preliminary information on a new product foreseen to be developed.
