The SGM42541 is a dual H-bridge motor driver suitable for automated positioning and movement control in equipment such as printers, scanners and robotic mechanisms. The SGM42541 has two H-bridge drivers, and can drive a bipolar stepper motor or two DC motors. The output driver block for each consists of N-MOSFETs configured as full H-bridge to drive the motor windings. With proper heatsinking, the SGM42541 can deliver up to 2.5A peak output current per channel (at VM = 24V and TJ = +25℃).
A simple parallel digital control interface is compatible with industry-standard devices. Decay mode is programmable. Fast, slow and mixed decay modes can be provided according application requirements. A 2-bit current control scheme allows up to 4 discrete current levels. A number of protection features are provided in the device including over-current, short-circuit, under- voltage lockout and thermal shutdown.
The SGM42541 is available in a Green TSSOP-28 (Exposed Pad) package.
