The SGM42531 device is a brushed DC motor driver. This device integrates four N-MOSFETs, which can supply up to 3.6A peak current at 28V voltage.
The SGM42531 supports IN1/IN2 PWM interface. PWM signal can be implemented on the input interface to adjust motor speed. Customer can adjust PWM current limit or torque in real-time by VREF pin with a controller’s DAC output or PWM signal after RC filter.
The SGM42531 integrates current sensing function which allows for the device to regulate the current during motor startup or stall event, saving PCB layout area and system cost. Current limit level can be adjusted by the external voltage reference on VREF pin. Additionally, the device provides a current proportional to the output load current, a resistor connecting from IPROPI pin to ground converts the proportional current to voltage for microcontroller ADC current sensing.
A number of protection features are provided in the device including over-current, short-circuit, under-voltage lockout and thermal shutdown. When the fault condition is removed, the device automatically resumes normal operation.
The SGM42531 is available in a Green SOIC-8 (Exposed Pad) package.
