The DHB class is designed to control brushed DC motors with performance up to 50 Amps, and peaks of 100 Amps.
The DHB-12V is a motor control board that outperforms the MC33886 motor control module or the classic L298.
First of all, it should be said that alternatives to this module capable of handling 50 Amps per channel on brushed DC motors are rare on the market.
Another important point is that its control module performs very well in terms of motor start-up speed and energy efficiency. It can in fact withstand a high current overload.
This control module also has a braking function that can quickly stop the motor, and the operation is very simple.
Its performance is better than that of the MC33886 chip control module.
Sturdy, efficient, high-quality MOSFETs.
The converter module contains a full-bridge driver chip and MOSFETs with low internal resistance.
Il driver IC full-bridge riduce al minimo la perdita di commutazione del MOSFET e migliora l’efficienza energetica.
The MOSFET driver chip includes hardware braking and motor power monitoring functions.
The MOSFET's ability to withstand current surges is particularly notable.
As a result, the MOSFET channel can be switched on quickly to improve the motor's speed curve, and can also brake the motor rapidly.
This function allows the robot to start or stop quickly.
Finally, here are some physical specifications of the DHB module:
The converter module weighs 15 grams. It can operate with a PWM duty cycle of 0%-98%, which a common drive module cannot support.
Dimensions:
6cm x 4.5cm x 1.9cm / 2.36inch x 1.77inch x 0.75inch.
Control definitions:
Rotazione motore in avanti:
EN = 1, RPWM = PWM, LPWM = 1, DIS = vuoto;
Rotate reverse:
EN = 1, RPWM = 1, LPWM = PWM, DIS = vuoto;
Arresto e freno:
EN = 1, RPWM = 1, LPWM = 1, DIS = vuoto;
Arresto ma senza freno:
EN = 0, RPWM = 1, LPWM = 1, DIS = vuoto;
Uso inibito:
EN = X, RPWM = X, LPWM = X, DIS = 1
