          Single H-Bridge Motor Driver
          Single H-Bridge Motor Driver

          The SGM42609 provides a single bridge motor driver solution for battery-powered toys, toothbrushes and other low-voltage or battery-powered motion control applications. The device has one H-bridge driver, and can drive one DC brush motor, solenoid, or other inductive load.

          The output driver block of H-bridge consists of N-channel power MOSFETs configured as an H-bridge to drive the motor windings. H-bridge includes circuitry to regulate or limit the winding current.

          With proper PCB design, H-bridge of the SGM42609 is capable of driving up to 1.5A RMS (or DC) continuously, at +25 with a VCC supply of 5V. It can support peak current of up to 2A. Current capability is reduced slightly at lower VCC voltage.

          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 SGM42609 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 both IN1 and IN2 are low for more than tsleep, the SGM42609 will enter into sleep state automatically.

          The SGM42609 is available in Green MSOP-10 and TDFN-3×3-10L packages. It operates over an ambient temperature range of -40 to +125.
