MP6540H/MP6540HA DC Motor Drivers

MPS' 50 V, 5 A and 6 A, three-phase power stage drivers offer PWM and enable inputs

Image of MPS' MP6540H/MP6540HA DC Motor Drivers The MP6540H and MP6540HA from Monolithic Power Systems are three-phase brushless DC motor drivers. These devices integrate three half-bridges consisting of six N-channel power MOSFETs, pre-drivers, gate drive power supplies, and current-sense amplifiers. The MP6540H has enable (EN) and PWM inputs for each half-bridge, while the MP6540HA has separate high-side (HS) and low-side (LS) inputs, otherwise they are identical. The MP6540H can deliver up to 6 A of peak current and 5 A of continuous output current, based on thermal and PCB conditions. The MP6540H uses an internal charge pump to generate the gate drive supply voltage for the high-side MOSFETs, and a trickle charge circuit that maintains sufficient gate drive voltage to operate at 100% duty cycle. Internal safety features include thermal shutdown, undervoltage lockout (UVLO), and overcurrent protection (OCP). The device is available in a QFN-26 (5 mm x 5 mm) package.
