Product Description

Description:

The motor driver can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four modes of operation – CW, CCW, short brake and stop. The two motor outputs (A and B) can be controlled separately, the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin must be pulled high to bring the motor out of sleep mode.

The logic supply voltage (VCC) can be between 2.7 and 5.5vdc, while the motor supply (VM) is limited to a maximum voltage of 15VDC. Output current is rated up to 1.2A per channel (or up to 3.2A for a short, single pulse).

The board comes with all components installed as shown. Decoupling capacitors are included on both supply lines. All pins of the pins are broken into two 0.1″ pitch headers; The pins are arranged so that the input pins are on one side and the output pins are on the other.

Features:

• Supply voltage: VM=15V max, VCC=2.7-5.5V
• Output current: Iout = 1.2a (average) / 3.2a (peak)
• Standby control to save energy
• CW/CCW/short brake/stop motor control modes
• Built-in thermal shutdown circuit and low voltage detection circuit
• All pins are broken to 0.1″ spaced pins
• Filter capacitors on both supply lines
