About This Product

■Summary

The MP6543C is a three-phase brushless DC (BLDC) motor driver with three integrated half-bridges consisting of six N-channel power MOSFETs, six predrivers, two gate driver supplies, and three current sense amplifiers. Each half-bridge includes an enable (EN) input and a pulse-width modulation (PWM) input. The MP6543C can deliver up to 1.2A continuous output current (IOUT) over a wide 3V to 22V input voltage (VIN) range. The internal current sensing circuit does not require a low resistance shunt resistor. Each half-bridge has independent ground pins (LSSA, LSSB, and LSSC) that allow current to be measured through external shunt resistors. This allows MP6543C to be used for various application requirements. An internal charge pump generates the gate driver supply voltage for the high-side MOSFET (HS-FET). A trickle charge circuit maintains sufficient gate driver voltage for 100% duty cycle operation. Extensive protection features include configurable overcurrent protection (OCP), undercurrent lockout (UVLO) protection, and thermal shutdown. The MP6543C is available in a QFN-24 (3mm x 4mm) package with an exposed thermal pad.
