1. Applications

This evaluation board can be used to control two single-phase DC motor, recommended supply

voltage is range from 2.5V to 14V, and the maximum drive current is up to 0.6A for one channel.

2. Input logic

The MP6514 can drive two DC motors in a single-ended connection with separate controls for the

high-side or low-side MOSFETs. The motor can be connected to either the supply or GND.

If all input pins (HIN1, HIN2, LIN1, and LIN2) remain at a low level within a certain time, then the

MP6514 enters a low-power sleep mode. In this state, all unnecessary internal circuitry is powered

down.

3. Setup Condition

a. Preset power supply of 2.5V to 14V between on VCC and GND terminal.

b. The connector INPUT/HIN(X) / LIN(X) should be connected to input signals, and refer above

table to find the corresponding control logic.

c. The connector OUT1 and OUT2 should be connected to the motor winding terminals. one

winding should be connected to OUT1/OUT2, while the other should be connected to VCC/GND.

d. Turn on power supply.
