Description

The STGAP2S is a single gate driver which provides galvanic isolation between the

gate driving channel and 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 suitable for mid and high power applications such as power conversion

and motor driver inverters in industrial applications. The device is available in

two different configurations. The configuration with separated output pins allows

to independently optimize turn-on and turn-off by using dedicated gate resistors.

The configuration featuring single output pin and Miller CLAMP function prevents

gate spikes during fast commutations in half-bridge topologies. Both configurations

provide high flexibility and bill of material reduction for external components.

The device integrates UVLO and thermal shutdown protection functions to facilitate

the design of highly reliable systems. Dual input pins allow the selection of signal

polarity control and implementation of HW interlocking protection to avoid cross-

conduction in case of controller malfunction. The input to output propagation delay

is less than 75 ns, which delivers high PWM control accuracy. A standby mode is

available to reduce idle power consumption.
