MP6534

The MP6534 is a gate driver IC designed for 3-phase, brushless DC motor driver applications. It is capable of driving three half-bridges consisting of six N-channel power MOSFETs up to 55V. The MP6534 includes a 500mA buck regulator to generate local power for microcontrollers or other circuitry. The MP6534 uses bootstrap capacitors 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 protection, under-voltage lockout (UVLO), and thermal shutdown. The MP6534 is available in a 40-contact QFN (5mmx5mm) package with an exposed thermal pad.
