Single Supply Eliminates Need for External LDO
Allegro MicroSystems, LLC introduces a new automotive bipolar stepper motor driver IC or dual DC motor driver IC that is designed for pulse-width-modulated (PWM) control of low-voltage stepper motors and dual or single high current DC motors. Allegro’sAMT49702is capable of output currents up to 1 A per channel and operating voltages from 3.5 to 15 V. Key applications include:Heads-up-Display (HUD)– mirror positioning and dust cover, Navigation – screen lift, Driver Attention Monitor – camera movement or focus, and Steering Wheel Feedback – vibration alert.
TheAMT49702is an automotive-grade device and is tested across extended temperature and voltage ranges to ensure compliance inautomotiveorindustrial applications. It 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.
