The MP6640 is a 3-phase brushless DC (BLDC) motor driver that integrates three half-bridges, each consisting of 6 N-channel power MOSFETs, along with pre-drivers and gate drive power supplies.

The MP6640 features a serial peripheral interface (SPI) for complete configurations and detailed diagnostics, as well as three configurable pulse-width modulation (PWM) generators are integrated for BLDC motor operation.

The MP6640 can deliver up to 2.5A of continuous current (depending on thermal and PCB conditions), with an adjustable over-current protection (OCP) threshold. It uses an internal charge pump to generate the gate drive supply voltage for the high-side MOSFETs (HS-FETs).

Internal safety features include thermal shutdown, under-voltage lockout (UVLO), and OCP.

The MP6640 is available in a QFN-16 (2mmx2.5 mm) package.
