GENERAL DEscriptION

The SGM42505 and SGM42506 devices are brushed DC motor drivers. These devices integrate four NMOSFETs, which can supply up to 3.6A peak current at 40V voltage.

The SGM42505 supports IN1/IN2 PWM interface and the SGM42506 supports PH/EN 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.

A number of protection features are provided in the device including over-current, short-circuit, under-voltage lockout and thermal shutdown. When the fault conditionm is removed, the device automatically resumes normal operation.

The SGM42505 and SGM42506 are available in a Green SOIC-8 (Exposed Pad) package.
