Note that the output is only active while the corresponding H-bridge is driving; it is inactive low when mc33926 dual motor driver is braking or the motor outputs are high impedance floating. If the driver is braking, current will continue to circulate through the motor, but the voltage on the FB pin will not accurately reflect the motor current. This shield makes it easy to control two brushed DC motors with your Arduino mc33926 dual motor Arduino-compatible board. These great drivers also offer current-sense feedback and accept ultrasonic PWM frequencies for quieter operation.

In our tests, the shield was able to deliver 5 A to both channels simultaneously for 10 s before the thermal protection started reducing the current. The shield delivered 4 A on both channels for 37 s, and at 3 A it was able to operate continuously for over 10 minutes without triggering current limiting or thermal protection. On motor voltage only; logic voltage does not have mc33926 dual motor protection.

Protection The MC has under-voltage, over-current, and over-temperature protection. Included Hardware A pin straight breakaway male header is included with the MC mc33926 dual motor carrier board, which can be used to connect the PCB to perfboards or breadboards. The MC dual motor driver contains protections against under-voltage, over-current, and over-temperature, that are reported by a low state on the SF pin.

We recommand to stay with currents under 3A and to mc33926 dual motor a heat sink if needed. The motor driver has a feature that allows it to gracefully reduce current as the current exceeds 5A or as the chip temperature approaches its limit. Categories Menu Motors.

Output slew rate selection input. However, the actual current it can deliver depends on how well you can keep it cool. The motor driver board mc33926 dual motor designed to draw heat out of the motor driver chips, but performance can be improved by adding heat sinks.

The feedback and error flag outputs are optionnal. The Mc33926 dual motor pin disables the motor driver for both motors, putting the H-bridges in a low-current sleep mode default mode. You should therefore pull this input high before commanding your motors. This expansion board is essentially a breakout board for two MC motor driver ICs with additional mc33926 dual motor circuitry to simplify the motor control, so the datasheet is your best resource for answering questions not covered here.

Dual Motor Driver MC33926

However, the motor driver board provides a set of three through-holes where you mc33926 dual motor conveniently connect an appropriate voltage regulator, allowing the motor supply to also power the Raspberry Pi see the Powering the Raspberry Pi from the motor driver board section below. A reverse-voltage protection circuit helps prevent damage to the board in case the motor power supply is connected backward. The reverse-protected input voltage can be accessed for use in other circuits through the mc33926 dual motor pins labeled VOUT on the left side of the board.

Pololu Dual MC33926 Motor Driver Shield for Arduino

The dual MC motor driver carrier is mc33926 dual motor breakout board featuring two Freescale MC H-bridge ICs. For a single-driver version of this board, please consider the MC motor driver carrier.

This shield makes it easy to control two brushed DC motors with your Arduino or Arduino-compatible board. Its dual MC motor drivers operate from 5 to 28 V and can deliver a continuous 3 A per motor. Pololu dual MC motor driver shield, assembled and connected to an Mc33926 dual motor.
