Product description: MP6550 - single-channel motor controller 22 V / 1.7 A - Pololu 4733
Driver based on the MP6550 chip that allows you to control the speed and direction of one DC motor . It works with motors powered by a voltage of 1.8 V to 22 V , with a continuous current consumption of up to 1.7 A. The controller can also withstand several-second current surges of up to 2.5 A.
The set also includes a goldpin strip intended for self-soldering.
Pins of the MP6550 single-channel motor driver.
Pins of the MP6550 driver
- VIN - engine supply voltage in the range from 1.8 V to 22 V with protection against reverse connection
- GND - module ground
- VM - motor supply voltage in the range from 1.8 V to 22 V without protection against reverse connection.
- OUT1, OUT2 - outputs for connecting motor terminals
- IN1, IN2 - PWM control signal
- SLEEP - logic input that switches the system to sleep
- ISET - current detection and limiting pin; a 2 kΩ resistor is connected to ground from this pin
- VISEN - current sensor output; this pin provides an analog feedback voltage of 200mV/A
- V3P3 - 3.3V output; disabled by default
Status table
| IN1 | IN2 | OUT1 | OUT2 | Operating mode |
|---|---|---|---|---|
| 0 | 0 | WITH | WITH | free running outputs disconnected |
| PWM | 0 | PWM (H/Z) | PWM (L/Z) | forward rotation / deceleration at PWM speed % |
| 0 | PWM | PWM (L/Z) | PWM (H/Z) | reverse rotation / deceleration at PWM speed % |
| PWM | 1 | L | PWM(L/H) | reverse rotation / deceleration at 100% speed - PWM % |
| 1 | PWM | PWM(L/H) | L | forward rotation / deceleration at 100% speed - PWM % |
| 1 | 1 | L | L | stop (outputs shorted to ground) |
