Description
Motor drive module is ideal for use in battery-powered smart car, toy cars, robots. Supply voltage 2V ~ 10V, can drive two DC motors or a 4-wire 2-phase stepper motors, can achieve forward rotation or reverse rotation, it is possible to control the rotation speed. Each can provide continuous current of 1.5A, peak current up to 2.5A, thermal protection and can be automatically recovered.
Power positive and negative reversed will definitely cause damage to the circuit.
Output is shorted to ground or short circuit, and the motor stall, the chip will be heat protection, but in the near or more than 10V voltage and peak current greater than 2.5A situation can also cause chip burned.

Features
Dual H-bridge motor driver, can drive two DC motors or a 4-wire two-phase stepper motor.
The module supply voltage 2V-10V.
Signal input voltage 1.8-7V.
Single operating current 1.5A, peak current up to 2.5A, low standby current (less than 0.1uA).
Built-in common conduction circuit, when the input pin is left floating, the motor does not malfunction.
Built-in thermal protection circuit with hysteresis effects (TSD), without worrying about engine stall.
