Description

The STGAP2HD is a dual gate driver which provides galvanic isolation between

each gate driving channel and the low voltage control and interface circuitry. The

gate driver is characterized by 4 A current capability and rail-to-rail outputs, making

it suitable for mid and high power applications such as power conversion and

industrial motor driver inverters. The separated output pins allow to independently

optimize turn-on and turn-off by using dedicated gate resistors, while the Miller

CLAMP function allows avoiding gate spikes during fast commutations in half-bridge

topologies. The device integrates protection functions: dedicated SD and BRAKE

pins are available, UVLO and thermal shutdown are included to easily design high

reliability systems. In half-bridge topologies the interlocking function prevents outputs

from being high at the same time, avoiding shoot-through conditions in case of wrong

logic input commands. The interlocking function can be disabled by a dedicated

configuration pin, so to allow independent and parallel operation of the two channels.

The input to output propagation delay results are contained within 75 ns, providing

high PWM control accuracy. A standby mode is available in order to reduce idle

power consumption.
