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 drive r power supplies, and three current-sense amplifiers. The MP Q6541-AEC1 has ENBL and PWM inputs for each half-bridge; the MPQ6541A- AEC1 has separate high-side (HS) and low-side (LS) inputs. Otherwise, these parts are identical. References to the MP Q6541-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 drive r voltage to operate at 100% duty cycle. Internal safety features include thermal shutdown, under -voltage lo ckout (UVLO), and over-current protection (OCP). The MPQ6541-AEC1 is available in a TQFN-26 (6mmx6mm) package.
