Description

The EVLSTGAP3S6S is a half-bridge evaluation board designed to evaluate the

STGAP3S6S isolated single gate driver.

The STGAP3S6S is characterized by 6 A current capability, rail-to-rail outputs and

optimized UVLO and DESAT protection thresholds for SiC MOSFETS, which makes

the device optimal for high-power motor drivers in industrial applications.

The gate driver has a single output pin and a driver line for an external Miller CLAMP

N-channel MOSFET, which optimizes positive and negative gate spikes suppression

during fast commutations in half-bridge topologies.
