MP6543H Overview
The MP6543H family of products (MP6543H, MP6543H-A, and MP6543H-B) are three-phase brushless DC motor drivers. They integrate three half-bridges, consisting of six N-channel power MOSFETs, as well as pre-drivers, gate drive power supplies, and current-sense amplifiers. The MP6543H has enable (EN) and PWM inputs for each half-bridge.
