- Programmable OCP Threshold
- Support 100% Duty Cycle Operation
- OCP, OTP
- Fault Indication Output
5V to 60V, Three-Phase Brushless DC Motor Pre-Driver AEC-Q100 Qualified
The MPQ6531 is a gate driver IC designed for three-phase brushless DC motor driver applications. It is capable of driving three half-bridges consisting of six N-channel power MOSFETs up to 60V.
The MPQ6531 integrates a regulated charge pump to generate gate drive power, and uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal trickle-charge circuit maintains a sufficient high-side gate driver voltage at 100% duty cycle.
Internal safety features include programmable short-circuit protection, over-current protection, adjustable dead-time control, under-voltage lockout, and thermal shutdown.
The MPQ6531 is available in a 4mmx5mm QFN-28 package with an exposed thermal pad.
