Driver Monitoring Systems
Preventing accidents caused by driver inattention or drowsiness is a primary goal for modern ADAS. This requires a system that can reliably monitor the driver's state without being intrusive.
Allegro's infrared LED drivers, designed for the pulsed infrared LEDs used in DMS, enable these systems with solutions that reduce size, improve EMI performance, and include fault monitoring to achieve high ASIL ratings. To create a safer driving experience by enabling the vehicle to alert a distracted or drowsy driver, forming a critical layer of active safety in the journey towards autonomous driving.
Featured Products
A8587
The A8587 is a high-frequency step-down switching regulator with an integrated high-side power MOSFET. It provides up to 2 A output current. The A8587 can achieve fast transient response using current-mode control and simple external compensation.
A8651
The A8651 offers efficient and flexible power conversion for low-voltage applications, featuring dual 2A synchronous buck regulators with adjustable output voltage, synchronizable switching frequency, and independent enable/NPOR outputs.
A8591
The A8591 is designed to provide the power supply requirements of next-generation car audio and infotainment systems.
A8650
The A8650 is an adjustable frequency, high output current, PWM regulator that integrates a high-side, P-channel MOSFET and a low-side, N-channel MOSFET.
