MP6541

MP6541

40V, 8A, Three-Phase Power Stage with PWM and ENBL Inputs

Datasheet

Description

The MP6541 is a three-phase brushless DC (BLDC) motor driver with three integrated half-bridges, consisting of six N-channel power MOSFETs. The MP6541 also integrates six pre-drivers, two gate drive power supplies, and three current-sense amplifiers.

The MP6541 integrates enable (ENBL) and pulse-width modulation (PWM) inputs for each half-bridge. The MP6541A integrates separate high-side (HS) and low-side (LS) inputs. Otherwise, the parts are identical. References to the MP6541 in this datasheet also apply to the MP6541A, unless otherwise noted.

The MP6541 can deliver up to 12A of peak output current (I_OUT) for 1 second, and up to 8A of continuous I_OUT (depending on thermal and PCB conditions). The device uses an internal charge pump to generate the gate drive supply voltage for the high-side MOSFETs (HS-FETs), and a trickle charge circuit that maintains sufficient gate drive voltage to operate at 100% duty cycle.

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

The MP6541 is available in a TQFN-26 (6mmx6mm) package.
