Product Description

The MP6531A is a gate driver IC designed for three-phase, brushless, DC motor driver applications. The MP6531A is capable of driving three half-bridges consisting of six N-channel power MOSFETs up to 60V. The MP6531A uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal trickle-charge circuit maintains a sufficient gate driver voltage at 100% duty cycle. Internal safety features include programmable over-current protection (OCP), adjustable dead-time control, under-voltage lockout (UVLO), and thermal shutdown. The MP6531A is available in 28-pin TSSOP-EP (9.7mmx6.4mm) and QFN-28 (4mmx4mm) packages with exposed thermal pads on the back.
