The SGM42403 consists of four identical low-side drivers with over-current protection. It has integrated diodes to discharge the inductive load energy such as unipolar stepper motors, DC motors, relays, solenoids or other loads when output is turned off.
The SGM42403 can provide continuous output current up to 1.5A (1-channel on) or 800mA/CH (4-channel on) by the SOIC package at +25℃. And its continuous output current capability is up to 2A (1-channel on) or 1A/CH (4-channel on) by the TSSOP package at +25℃.
The device has multiple protection functions, including under-voltage lockout, over-current, short-circuit protection and thermal shutdown. Over-current and over-temperature can be reported by the nFAULT pin.
The SGM42403 is available in Green SOIC-20 and TSSOP-16 (Exposed Pad) packages.
