Automotive Quad Channel Low-side Driver with Serial Interface Option

SGM42404Q.pdf

The SGM42404Q consists of four identical low-side drivers with over-current protection. It has inductive clamp circuit to discharge the inductive load energy when the output is turned off such as unipolar stepper motors, DC motors, relays, solenoids or other loads.

The SGM42404Q provides a serial interface, which can read/write the data register/control register (configuring the energizing time & PWM duty cycle) through the serial interface, and also can diagnose the open-load or over-current fault condition. Multiple devices can be daisy-chain connected together to save the microcontroller resource.

The device has multiple protection functions, including open-load detection, over-temperature shutdown, over-current and short-circuit protections. Fault conditions are indicated on the SDO/nFAULT pin.

The SGM42404Q is available in a Green TSSOP-16 (Exposed Pad) package.
