STMicroelectronics Demonstration Board for STGAP2HSCM Isolated 4 A Single Gate Driver Negative Gate Driving for

The STMicroelectronics EVALSTGAP2HSCM is an isolated single gate driver. The gate driver is characterized by 4 A current capability and rail-to-rail outputs, making the device suitable also for high power inverter applications such as motor drivers in industrial applications equipped with MOSFET / IGBT power switch. The configuration featuring single output pin and Miller CLAMP function allows avoiding gate spikes during fast commutations in half-bridge topologies. The device integrates protection functions: UVLO and thermal shutdown are included to easily design high reliability systems.
