Product Overview
Exact MPN is explicitly listed in the official datasheet as the MPQ6541A-AEC1, a 40V, 8A three-phase BLDC power stage with separate high-side and low-side inputs.
HS/LS inputs permit direct independent control of each transistor, useful where commutation or FOC control requires explicit switch control. Automatic synchronous rectification and the charge pump support efficient high-duty-cycle operation.

Selection Notes
HS/LS versus PWM/ENBL control; automotive qualification; 40V margin; current/thermal capability; wettable-flank manufacturing.
Match bridge topology, motor voltage/current, integrated-FET architecture and control interface before comparing protection or thermal features.
Manufacturer Decision-Relevant Notes
Operating supply: 4.75V to 40V. ; Output: 8A continuous; up to 12A peak for 1s, dependent on thermal/PCB conditions. ; MOSFET resistance: 15mΩ per FET. ; Inputs: separate HS and LS inputs. ; Operating junction temperature: -40°C to +125°C. ; Thermal resistance: θJA 21.4°C/W; θJC 12.8°C/W. ; Quiescent current: 4mA typ, 8mA max, nSLEEP=1, ENx=0, VIN=24V. ; Sleep current: 1µA typ, VIN=24V.
Design Considerations
-
- Confirm the controller supplies correct HS/LS dead time and prevents shoot-through. 2. Validate the 8A/12A thermal profile using the θJA/θJC values and actual PCB stack-up. 3. Use the specified charge-pump capacitors: 0.1µF CP1–CP2 and 1µF VIN–VCP. 4. Verify HS/LS logic thresholds, fault handling, and startup sequencing. 5. Confirm AEC-Q100 Grade 1 evidence and wettable-flank assembly controls.
Application Fit
BLDC and PMSM motor drivers; automotive motor applications such as LiDAR are identified by MPS.
