The SGM42406 consists of 8 identical low-side drivers with series protection functions. The device integrates diodes for inductive load demagnetizing, and can drive different kinds of loads. For example, brushed motor, relays, LEDs, unipolar stepper motor and so on.
The SGM42406 can provide continuous output current up to 930mA (1-channel on) or 310mA/channel (8-channel on) by TSSOP-16 package at +25℃. And it can provide continuous output current up to 1000mA (1-channel on) or 510mA/channel (8-channel on) by TSSOP-16 (Exposed Pad) package at +25℃. The SGM42406 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 nFAULT pin.
The SGM42406 is available in Green TSSOP-16 and TSSOP-16 (Exposed Pad) packages.
