SMA6863MH

Overview

The SMA6863MH is a high-voltage three-phase motor driver IC manufactured by Sanken Electric USA Inc. It integrates power MOSFETs, pre-driver ICs, and bootstrap diodes with current limiting resistors into a single package. The device supports breakdown voltages up to 500 V and output currents ranging from 1 A to 3 A. It utilizes a 24-SSIP (formed leads) through-hole package. The operating junction temperature range extends from -20°C to 150°C.
