Allegro’s AMT49702 is capable of output currents up to 1A per channel and operating voltages from 3.5-15V. 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.
The AMT49702 is an automotive-grade device and is tested across extended temperature and voltage ranges to ensure compliance in automotive or industrial 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.
