I. Product Description
The MP6531AGR is a gate driver IC designed for three-phase brushless DC motor drive applications. The MP6531AGR is capable of driving three half-bridges, each comprising six 60V N-channel power MOSFETs. The MP6531AGR utilises a bootstrap capacitor to supply power to the upper MOSFET drivers. An internal trickle-charge circuit maintains a sufficient gate drive voltage, supporting 100% duty cycle operation. Integrated safety protection features include programmable overcurrent protection (OCP), adjustable dead-time control, under-voltage lock-out protection (ULVO) and over-temperature shutdown protection.
Mingjiada Electronics has been a long-term supplier of the MP6531AGR series (including models such as the MP6531AGR-P and MP6531AGR-Z), whilst also providing professional electronic component recycling services.

II. MP6531AGR Key Specifications
1. Electrical Voltage Parameters
Input supply voltage (VIN) operating range: 5V to 60V
Internal regulated charge pump output VREG: typically 11.5V
Undervoltage lockout (UVLO) threshold: VIN typically 4.2V; the chip locks the output when the voltage falls below this threshold
Bootstrap trickle charging support: continuous drive with 100% duty cycle
2. Drive Output Capability
Peak current per gate drive channel: 800mA
Three-phase, six-channel independent drive outputs (3 high-side HS channels, 3 low-side LS channels), with independent logic control per phase
Dead time: Programmable via external resistor on the DT pin, preventing short-circuiting between upper and lower bridges
3. Protection Circuit Parameters
Programmable external MOS overcurrent protection (OCP), with customisable threshold via external sampling resistor
Thermal shutdown (TSD): Automatic shutdown of all six drive channels when chip junction temperature exceeds the limit
Full-channel anti-short-circuit dead-time control and bootstrap undervoltage protection
4. Package and Temperature
MP6531AGR standard package: 28-QFN (4 mm × 4 mm), with an exposed rear heat sink pad (EP)
Operating temperature range: -40 °C to +125 °C (wide-temperature industrial grade)

III. Product Features and Advantages
Wide input voltage range from 5 V to 60 V
Bootstrap gate drive maintained by a trickle-current charging circuit, supporting 100% duty cycle operation
Low-power sleep mode for battery-powered applications
External MOSFET programmable overcurrent protection
Adjustable dead-time control prevents conduction through both upper and lower switches
