Pololu DRV8801 Single Motor Driver Carrier 1.A. Texas Instruments Motor Driver Breakout Board TI

Item number: PO-2136

EAN: 4251326822098

This tiny breakout board for TI's DRV8801 offers a modern alternative to classic motor drivers such as the L293D, SN754410 and L298N. It can deliver a continuous 1A (2.8A peak) to a single motor and offers a wide operating voltage range from 8V to 36V. The DRV8801 features a simple bipolar speed/direction interface, low-current feedback and built-in protection against undervoltage, overcurrent and overtemperature.

The Texas Instruments DRV8801 is a tiny H-bridge motor driver IC that can be used for bidirectional control of a single DC motor at 8V to 36V. It can supply up to about 1A continuously and tolerate peak currents up to 2.8A for a few seconds, making it a good choice for small motors running at a wide voltage range.

The board is equipped with all its SMD components, including the DRV8801. 


  • Drive of a single DC motor with rust Motor supply voltage: 8 V to 36 V
  • Logic power supply voltage: 3.3 V to 6.5 V
  • Output current: 1 A continuous (2.8 A peak)
  • Simple interface requires only two I/O lines (one for the direction and one for the speed).
  • Current output proportional to motor current (approx. 500 mV per A) The inputs are 3V and 5V compatible.

The BRAKE pin determines whether the motor will brake or leak when the PWM pin is low. The circuit board pulls it up, which corresponds to braking (both motor outputs are short-circuited by ground). If you set the BRAKE pin low, the outputs will always roll out when the PWM pin is low (both motor outputs are off). We generally recommend keeping this value high while a PWM signal is applied to the PWM pin to enable operation of the drive brake (or "slow-decay");as this typically provides a more linear relationship between PWM duty cycle and motor speed than the drive ratios (or "fast-decay") and can lead to better performance at lower duty cycles.

Note: When braking, the driver brakes weakly because the MODE2 pin of the DRV8801 is pulled low on the circuit board. The MODE2 pin is not accessible to the user.

The SLEEP pin is pulled up by a 10k resistor on the board and may remain disconnected if you do not want to use the DRV8801's low-power Sleep mode. The FAULT pin is an open drain output that is weakly driven by the chip in the event of overcurrent, overtemperature, or undervoltage. The circuit board contains a pull-up resistor at this pin so that no external pull-up is required.

Note that the FAULT pin is a pure status signal that does not interfere with device functionality, so a low FAULT signal does not necessarily mean that the driver outputs are disabled .

For example, the driver starts normal operation as soon as the motor supply voltage is above 8 V, but the FAULT output is low until the motor supply voltage reaches about 12 V. The driver will not start normal operation until the FAULT output is low. The CS pin outputs an analog voltage proportional to the motor current (approximately 500 mV per A). In a typical application, power connections are made on one side of the board and control connections on the other side. Apart from motor and power connections, only DIR and PWM are required. A PWM signal can be applied to the PWM/ENABLE pin to achieve variable speed control in the direction determined by the state of the DIR/PHASE pin. The Trim board pulls PWM low by default so that the driver is only activated when this is the case. Pin is supplied with a high signal.

The DIR pin has no defined default state, which means that if the DIR pin remains separated, the outputs may behave irregularly while the PWM pin is high. The BRAKE pin determines whether the motor will brake or leak when the PWM pin is low. The circuit board pulls it up, which corresponds to braking.
