The MP6537 is a gate driver IC designed for three-phase, brushless DC motor driver applications. The MP6537 is capable of driving three half-bridges consisting of six N-channel power MOSFETs up to 100V.
The MP6537 uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal charge pump maintains the high-side gate driver if the output is held high for an extended period of time.
Full protection features include programmable over-current protection (OCP), adjustable dead-time control, under-voltage lockout (UVLO), and thermal shutdown.
The MP6537 is available in a QFN-28 (4mmx5mm) package with an exposed thermal pad.
