The MP6539B is a gate driver IC designed for three-phase, brushless DC motor driver applications. The MP6539B is capable of driving three half-bridges consisting of six N-channel power MOSFETs up to 100V. The MP6539B uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal charge pump maintains the high-side gate drive if the output is held high for an extended period of time. Internal safety features include shoot-through protection, adjustable dead-time control, under-voltage lockout (UVLO) and thermal shutdown. The MP6539B is similar to the MP6539. It does not implement auto bootstrap charging, does not include over-current protection and is powered only from the VDD pin (VIN and LDO have been removed).
- 120V VBST maximum voltage
- Integrated current-sense amplifier
- Low-power sleep mode for battery powered applications
- Adjustable dead-time control to prevent shoot-through
- Fault indication output
