A89103 Description
The A89103 is an N-channel power MOSFET driver capable of controlling five MOSFETs to provide motor-phase isolation and supply isolation in three-phase BLDC applications. Three floating gate-drive outputs maintain phase-isolator power MOSFETs in the on state, over the full supply range, with highphase voltage and high dv/dt on the motor-phase connection for 12 V and 48 V systems. Two additional floating gate drivers...
