A89103 3-Phase Battery Isolator MOSFET Drivers

Allegro MicroSystems A89103 3-Phase Battery Isolator MOSFET Drivers are N-channel power MOSFET drivers capable of controlling five MOSFETs to provide motor-phase and supply isolation in three-phase BLDC applications. Three floating gate-drive outputs maintain phase-isolator power MOSFETs in the on state, over the entire supply range, with high phase voltage and dv/dt on the motor-phase connection for 12V and 48V systems. Two additional floating gate drivers are provided to isolate the battery supply voltage in case of reverse battery or short-circuit conditions. The A89103 supports both source-to-source and drain-to-drain battery MOSFET isolation. An integrated charge-pump regulator provides the above-battery-supply voltage necessary to continuously maintain the power N-channel MOSFETs in the on state. The charge pump maintains sufficient gate drive power (>7.5V) for battery voltages as low as 4.5V with 100kΩ gate-source resistors.
