Description of product: Pololu DRV8833 - dual channel motor driver 10,8 V / 1.2 A

The module is based on a Texas Instruments DRV8833 is a dual driver siników DC. The advantages of the system are extremely small size - tile size case DIP 14-pin. The module can control the motors with a supply voltage range from 2.0 V to 11 V with a continuous current consumption to 1.2 V. the control Channels can be combined to improve the efficiency of current load - up to 2.4 A. the Kit includes module and connector goldpin.

The connection dual channel motor driver 10,8 V / 1.2 A - Pololu DRV8833

For proper operation of the module, you need to bring food - between the pins VIN and GND and connect insights, responsible for the movement of the engine, which is described in the table below. To control the speed of rotation necessary for control inputs by the user to signal PWM.

VINSupply voltage (2.7 V - 10.8 V)
GNDThe potential of mass of the system
VMMPower supply output protection against reverse connection of power supply.
AOUT1, AOUT2The output of the channel And managed contacts AIN1 and AIN2
BOUT1, BOUT2The output of channel B, controlled contacts BIN1 and BIN2
AIN1, AIN2The digital control inputs channel A. Possible connection of the PWM signal. Default in the low state.
BIN1, BIN2The digital control inputs channel B. Possible connection of the PWM signal. Default in the low state.
nSLEEPA low state causes the system to sleep mode - energy saving. Default in the high state (pull-up).
nFAULTThe output goes into a low state upon detection of errors due to too low supply voltage, high temperature or too much current.
AISENThe entry point to limit the current for channel A. Default in the low state without restrictions.
BISENThe entry point to limit the current for channel B. Default in the low state without restrictions.

To limit the current flowing

On the module there are fields solders, allowing the placement of resistors in the 1206 case or less. They serve to limit the current passing through the channel A and B. the details of the documentation system DRV8833.

Heat dissipation with two-channel motor driver 10,8 V / 1.2 A - Pololu DRV8833

System documentation DRV8833 indicates the maximum continuous current per channel is 1.5 A. the company Pololu Tests showed that when the attack of 1.5 And the temperature protection switches off the system after about a minute of continuous operation. Stable operation possible at a current of not lower than 1.3 And channel.
