MPQ6541GQKTE-AEC1 Datasheet | Monolithic Power Systems

MPQ6541-AEC1, MPQ6541A-AEC1 40V, 8A, Three-Phase Power Stage, AEC-Q100 Qualified DESCRIPTION The MPQ6541-AEC1 and MPQ6541A-AEC1 are three-phase brushless DC (BLDC) motor drivers with three integrated half-bridges. The three half-bridges consist of six N-channel power MOSFETs. The MPQ6541-AEC1 and MPQ6541A-AEC1 also integrate six pre-drivers, two gate driver power supplies, and three current-sense amplifiers. The MPQ6541-AEC1 has ENBL and PWM inputs for each half-bridge; the MPQ6541AAEC1 has separate high-side (HS) and low-side (LS) inputs. Otherwise, these parts are identical. References to the MPQ6541-AEC1 also apply to the MPQ6541A-AEC1, unless otherwise noted. The MPQ6541-AEC1 can deliver up to 12A of peak current for 1 second, or 8A of continuous current, depending on thermal and PCB conditions. The device uses an internal charge pump to generate the gate driver supply voltage for the high-side MOSFETs (HS-FETs), and a trickle charge circuit that maintains sufficient gate driver voltage to operate at 100% duty cycle. Internal safety Features include thermal shutdown, under-voltage lockout (UVLO), and over-current protection (OCP). The MPQ6541-AEC1 is available in a TQFN-26 (6mmx6mm) package.
