MP6543HGL-Z

Monolithic Power Systems · Brushless DC (BLDC) Motor Driver · QFN-24(3x4)

MP6543HGL-Z from Monolithic Power Systems, in a QFN-24(3x4). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 ENA input Enable input for phase A; logical high enables output, low produces high impedance.
2 ENB input Enable input for phase B; logical high enables output, low produces high impedance.
3 ENC input Enable input for phase C; logical high enables output, low produces high impedance.
4 PWMA input PWM input for phase A; controls half-bridge output when enabled (high = VIN, low = GND).
5 PWMB input PWM input for phase B; controls half-bridge output when enabled (high = VIN, low = GND).
6 PWMC input PWM input for phase C; controls half-bridge output when enabled (high = VIN, low = GND).
7 VIN power_in Input power supply; operating voltage range 3V to 22V.
8 LSS power_in Low-side source connection for all three phases; must be connected directly to ground.
9 SA output Phase A half-bridge output; switches between VIN and GND based on control logic.
10 SB output Phase B half-bridge output; switches between VIN and GND based on control logic.
11 SC output Phase C half-bridge output; switches between VIN and GND based on control logic.
12 LSS power_in Low-side source connection for all three phases; must be connected directly to ground.
13 VIN power_in Input power supply; operating voltage range 3V to 22V.
14 VCP power_out Charge pump output; provides VIN + 3.3V for high-side gate drivers.
15 GND power_in Ground reference.
16 VIN_LDO power_in LDO regulator input; operating voltage range 3V to 22V.
17 OC_ADJ input Over-current threshold configuration pin; floating sets 5.5A threshold, 0Ω to ground sets 4.7A threshold.
18 V3P3 power_out 3.3V regulated output with 100mA capacity.
19 N/C unconnected No internal connection.
20 nFAULT tri_state Open-drain fault output; pulls low if over-current protection or thermal shutdown occurs.
21 SOC output Current-sense output for phase C; sources/sinks current proportional to LS-FET current (1/4000 ratio).
22 SOB output Current-sense output for phase B; sources/sinks current proportional to LS-FET current (1/4000 ratio).
23 SOA output Current-sense output for phase A; sources/sinks current proportional to LS-FET current (1/4000 ratio).
24 nSLEEP input Sleep mode control input; pull low to enter low-power sleep mode with internal circuits disabled.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
