GENERAL DEscriptION

The SGM42540 is an integrated driver IC for driving one brushed DC motor in industrial applications. The device operates from a single power supply and supports a wide input supply range from 8V to 45V.

The PHASE and ENBL pins allow simple interfacing to controller circuits. The device has one H-bridge driver for driving a DC motor.

With proper heatsinking, the SGM42540 can deliver up to 5A peak or 3.5A continuous output current (at VM = 24V and TJ = +25℃). Five input pins (ISET0 - ISET4) are used for 32 current levels. The decay mode (slow or fast) can be selected by DECAY pin.

A number of protection features are provided in the device including over-current, short-circuit, under-voltage lockout and thermal shutdown.

The SGM42540 is available in a Green TSSOP-28 (Exposed Pad) package.
