MAX20086ATPA/VY+

Current Regulation/Management Overview

The MAX20086ATPA/VY+ is a dual camera power protector from the MAX20086–MAX20089 series, manufactured by Analog Devices Inc./Maxim Integrated. It delivers up to 600mA load current to each of its two output channels. The device operates from a 3V to 5.5V supply and supports a 3V to 15V camera supply input. Key electrical specifications include an input-to-output voltage drop of 110mV (typical) at 300mA, ±8% current-limit accuracy, and 26V short-to-battery isolation. It features individually protected outputs against short-to-battery, short-to-ground, and overcurrent conditions.

Current Regulation/Management Feature Summary

• Provides individual protection for output channels against short-to-battery, short-to-ground, and overcurrent conditions.
• Includes an I2C interface for reading diagnostic status and on-board ADC readings of current through each switch.
• Supports ASIL B compliance with additional diagnostic measurements for high-fault coverage.
• Features adjustable current limits ranging from 100mA to 600mA per channel.

Current Regulation/Management Applications

• Power-over-coax systems for radar modules
• Power distribution for camera modules
• Automotive safety applications requiring ASIL B/D compliance

Current Regulation/Management Procurement Notes

Verify the specific suffix 'ATPA/VY+T' matches the required reel quantity and tape-and-reel packaging configuration. Confirm that the AEC-Q100 qualification and ASIL B compliance ratings are explicitly stated in the official datasheet for this exact part number variant before integration into safety-critical designs.

Current Regulation/Management Selection Notes

Select this component when designing automotive camera or radar power systems requiring precise current limiting and comprehensive fault diagnostics. The dual-channel architecture suits applications needing independent control of two loads. Ensure the design accommodates the 3V to 15V input range and utilizes the I2C interface for real-time monitoring of voltage and current parameters.

Current Regulation/Management Part Context

This device belongs to the MAX20086–MAX20089 family of dual/quad camera power protectors. The series shares common features such as low voltage drop, soft-start capabilities, and small 4mm x 4mm 20-pin SWTQFN packaging. Variants within the family differ primarily in the number of output channels and specific diagnostic support levels.
