GENERAL DEscriptION

The SGM42600 is a motor driver device with two integrated H-bridges that can run one bipolar stepper motor or two DC brush motors. It can be used in a variety of applications such as printers and battery- powered toys.

Each H-bridge consists of four N-MOSFETs to drive one motor winding. The SGM42600 can supply up to 2A peak or 1.5A RMS output current (with proper heatsinking at VCC = 5V and TA = +25℃). At lower VCC voltages, the current capability is decreased slightly.

Internal protection functions are provided for over-current protection (OCP), power supply under-voltage lockout (UVLO), charge pump under-voltage lockout (CPUV) and over-temperature protection (OTP). Fault conditions are indicated by the nFAULT pin.

Sleep mode allows saving power when the device is not driving the motor. The SGM42600 will enter into sleep mode when nSLEEP is low.

The SGM42600 is available in Green TQFN-4×4-16L and TSSOP-16 (Exposed Pad) packages. It operates over an ambient temperature range of -40℃ to +125℃.
