DESCRIPTION

The SGM42600 provides a dual bridge motor driver solution for battery-powered toys, printers and other low-voltage or battery-powered motion control applications. The device has two H-bridge drivers, and can drive two DC brush motors, a bipolar stepper motor, solenoids, or other inductive loads. The output driver block of each H-bridge consists of N-channel power MOSFETs configured as an H-bridge to drive the motor windings. Each H-bridge includes circuitry to regulate or limit the winding current.

With proper PCB design, each H-bridge of the SGM42600 is capable of driving up to 1.5A RMS (or DC) continuously, at +25℃ with a VCC supply of 5V. It can support peak currents of up to 2A per H-bridge. Current capability is reduced slightly at lower VCC voltages.

Internal shutdown functions with a fault output pin are provided for H-bridge over-current protection, power supply under-voltage lockout, charge pump under-voltage lockout and over-temperature protection. If one of fault conditions happens, the SGM42600 would prevent each input PWM signal from driving H-bridge and H-bridge is in high impedance status. A low-power sleep mode is also provided to save power dissipation. If nSLEEP is low, the SGM42600 will enter into sleep state.
