Product Description

The MP6529 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 35V. The MP6529 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. Full protection features include programmable over-current protection (OCP), adjustable dead-time control, under-voltage lockout (UVLO), and thermal shutdown. The MP6529 is available in a 28-pin TSSOP (9.7mmx6.4mm) package with an exposed thermal pad and a 28-contact QFN (4mmx4mm) package with an exposed thermal pad.
