The MP6539 from Monolithic Power Systems is a gate driver IC for three-phase, brushless dc (BLDC) motors. The device is capable of driving three half-bridges consisting of six N-channel power MOSFETs rated for up to 100V.
The MP6539 uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal charge pump maintains the high-side gate driver if the output is held high for an extended period of time.
The MP6539 provides a full set of protection features, including programmable over-current protection for the external MOSFETs, adjustable dead-time control to prevent shoot-through, under-voltage lockout, and thermal shutdown.
The MP6539B is similar to the MP6539, except:
The MP6539 and MP6539B are supplied in either a TSSOP-28 package measuring 9.7 mm x 6.4 mm, or a 4 mm x 5 mm QFN-28. Both packages have an exposed thermal pad.
Monolithic Power Systems also supplies the MPQ6532, a gate driver IC for three-phase BLDC motors which can drive three half-bridges consisting of six N-channel power MOSFETs at an input voltage of up to 60 V. The AEC-Q100 qualified MPQ6532 is suitable for use in automotive actuators, pumps, and fans.
The MPQ6532 implements 120° commutation using three Hall sensor inputs. The PWM, DIR, and nBRAKE pins control the motor speed, direction, and braking.
Internal safety features include:
The device is supplied in a 4 mm x 5 mm QFN-28 package with an exposed thermal pad.
Board part number: EV6539-V-00A
The EV6539-V-00A is an evaluation board for the MP6539, a three-phase BLDC motor pre-driver. It operates from a supply voltage of up to 100 V.
The rotor position information is provided by Hall sensors assembled in the motor, and the driving control signals are generated by an external control device.
Board part number: EV6539B-F-00A
The EV6539B-F-00A is an evaluation board for the MP6539BGF, a three-phase BLDC motor pre-driver. It operates from a supply voltage of up to 100V.
The rotor position information is provided by Hall sensors assembled in the motor, and the driving control signals are generated by an external control device.
