AMT49702: Dual DMOS Full-Bridge Motor Driver

Designed for pulse-width-modulated (PWM) control of lowvoltage stepper motors and single and dual DC motors, the AMT49702 is capable of output currents up to 1 A per channel and operating voltages from 3.5 to 15 V.

The AMT49702 is an automotive-grade device and is tested across extended temperature and voltage ranges to ensure compliance in automotive or industrial applications.

The AMT49702 has an internal fixed off-time PWM timer that sets a peak current based on the selection of a current sense resistor. An output fault flag is provided that notifies the user of a TSD or overcurrent protection event.

The AMT49702 is supplied in a low-profile 16-lead TSSOP (suffix “LP”) with exposed power tab for enhanced thermal dissipation.
