The SGM42500 and SGM42501 devices are brushed DC motor drivers. Two logic inputs control the H-bridge driver, which consists of four N-MOSFETs that can control motors bi-directionally with up to 3.6A peak current at 40V voltage.
The SGM42500 supports IN1/IN2 PWM interface and the SGM42501 supports PH/EN interface. Internal synchronous rectification control circuitry is provided to lower power dissipation during PWM operation.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 condition is removed, the device automatically resumes normal operation.
The SGM42500 and SGM42501 are available in a Green SOIC-8 (Exposed Pad) package. They operate over an ambient temperature range of -40℃ to +125℃.
