I. Product Description
The MP6543HGL is a 3-phase brushless DC motor driver that integrates three half-bridges (comprising six N-channel power MOSFETs), a pre-driver, a gate driver power supply and a current sense amplifier. Each half-bridge in this device features enable (EN) and PWM input functions.
The MP6543HGL can deliver a continuous current of up to 2A (depending on ambient temperature and PCB thermal conditions) and features an adjustable overcurrent protection (OCP) threshold. It utilises an internal charge pump to supply power to the high-side MOSFET gate drivers and employs a trickle-charging circuit to maintain sufficient gate drive voltage for operation at 100% duty cycle. Internal safety features include over-temperature protection, under-voltage lock-out (UVLO) protection and over-current protection (OCP). The MP6543HGL is housed in a QFN-24 (3 mm × 4 mm) package with a heat sink pad.
Shenzhen Mingjiada Electronics Co., Ltd. — a long-term supplier of the MP6543HGL series (including models such as MP6543HGL-Z, MP6543HGL-P and MP6543HGL-A-Z), whilst also providing professional electronic component recycling services.

II. MP6543HGL Key Specifications
1. Electrical Voltage and Current Parameters
Input operating voltage VIN: 3V to 22V (wide voltage range)
Continuous output current per phase: 2A (subject to PCB heat dissipation and ambient temperature constraints)
Peak instantaneous output current: up to 6A
On-resistance (Rds(on)) of the integrated MOSFET: typically 110mΩ
Integrated LDO regulated output: 3.3V / 100mA, capable of powering Hall sensors and MCU peripherals
Undervoltage lockout (UVLO) threshold: All driver outputs automatically lock out when VIN falls below 2.7V
2. Control Input Architecture
Three independent channels: ENA/ENB/ENC (ENBL enable input), PWMA/PWMB/PWMC (PWM speed control inputs)
Input logic: ENx high level enables the channel; PWM controls output high/low; ENx low level puts the channel into high-impedance shutdown
Sleep pin nSLEEP: Low-power standby mode; disconnects the internal power circuit to reduce quiescent power consumption
3. Package and Physical Specifications
Standard package: QFN-24 (3 mm × 4 mm), with a large exposed heat sink pad (EP) on the rear
Number of pins: 24
Operating temperature range: Industrial grade -40 °C to +125 °C
4. Protection Circuit Parameters
Adjustable overcurrent protection (OCP): Short-circuit/overload thresholds can be customised via an external resistor connected to the OC_ADJ pin
Thermal shutdown (TSD): Automatically shuts down the three-phase output when the chip junction temperature exceeds the threshold; automatically resumes once the temperature has dropped
Bootstrap undervoltage protection; dead-time control to prevent through-conduction in the upper and lower bridges
Global fault alarm (nFAULT) pin; provides a pull-down output to signal a fault to the MCU in the event of an anomaly
5. Driver Power Supply Characteristics
Built-in charge pump drives the high-side MOSFET gates
Trickle-charging circuit, supporting continuous operation at 100% PWM full duty cycle
Automatic synchronous rectification to reduce motor conduction losses

III. MP6543HGL Product Features and Advantages
Wide operating voltage range: 3V to 22V, compatible with 5V / 12V / 18V bus systems
Fully integrated power stage: Features six built-in N-MOSFETs (RDS(ON) ≈ 110mΩ per device), eliminating the need for external MOSFETs
EN + PWM control interface (MP6543H type): Independent ENx / PWMx inputs per phase, simplifying peripheral logic
Integrated 3.3V/100mA LDO + charge pump: Supports 100% duty cycle operation
Integrated bidirectional current sense amplifier: Phase current sense signals output via SOA/SOB/SOC pins, reducing BOM costs
Automatic synchronous rectification (ASR): reduces freewheeling losses and improves efficiency
Programmable overcurrent protection (OCP): threshold set via the OC_ADJ pin
UVLO, over-temperature shutdown (TSD) protection & nFAULT fault indication​
Low-power sleep mode (nSLEEP), suitable for battery-powered devices
Continuous output current: 2A (typical, subject to junction temperature and PCB heat dissipation); peak current up to approximately 9A

IV. Typical Applications for the MP6543HGL
Three-phase brushless DC (BLDC) and permanent magnet synchronous (PMSM) motor drives
Consumer-grade drone gimbal motors, micro ducted fans
Robotic joint modules, servo gimbals
Small cooling fans, water pumps, air pumps
Electric toys, handheld power tools (low-voltage versions)
Office automation equipment (feed motors for printers and scanners)
