DC Motor Drive Module 2 Channel Reversing PWM Speed Dual H Bridge Stepper Controller
This motor drive module is ideal for use in battery-powered smart cars, toy cars, and robots. Supply voltage 2V ~ 10V, can drive two DC motors or 4-wire 2-phase stepper motors, can achieve forward rotation or reverse rotation, it is possible to adjust the rotation speed. Each can provide a continuous current of 1.5A, a peak current of up to 2.5A, thermal protection, and can be automatically restored.
Note:- Power positive and negative reversed will certainly cause damage to the circuit.
- Output is shorted to ground or output short circuit, and the motor stall, the chip will heat protection, but in the near or exceeding 10V voltage and the peak current is 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
- 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 the motor stall
- Small in size
- Lightweight

1. How does PWM control H-Bridge?
- The PWM signal controls how fast the motor turns, and the H-bridge acts as a switch, turning the supply voltage on or off based on the PWM signal.
2. How does a stepper motor work with PWM?
- PWM (Pulse Width Modulation) involves rapidly switching the output voltage to the motor on and off. This applies a very high voltage to the motor's coils (typically eight times the motor's nominal voltage), causing the current to rise quickly and be higher than it would be otherwise.
