MAX20089ATPB/VY+

Current Regulation/Management Overview

The MAX20089ATPB/VY+ is a quad camera power protector IC from Analog Devices. It delivers up to 600mA load current per output channel with individual protection against short-to-battery, short-to-ground, and overcurrent conditions. The device operates from a 3V to 5.5V supply and supports a 3V to 15V camera supply. Input-to-output voltage drop is 110mV typical at 300mA. It features an enable input and I2C interface for diagnostic status reading, including on-board ADC for current measurement. ASIL D compliant versions support additional diagnostic measurements.

Current Regulation/Management Feature Summary

• Provides independent overcurrent, short-to-battery, and short-to-ground protection for four output channels.
• Includes I2C interface and on-board ADC for real-time diagnostic monitoring of current and voltage.
• Features adjustable current limits ranging from 100mA to 600mA with high precision accuracy.
• Designed for safety-critical applications with ASIL D compliance and comprehensive fault diagnostics.

Current Regulation/Management Applications

• Power-over-coax systems for radar modules
• Camera module power distribution
• Automotive imaging systems requiring ASIL D compliance

Current Regulation/Management Procurement Notes

Verify the specific suffix 'ATPB/VY+' matches the required package and temperature grade in the official datasheet. Confirm ASIL D compliance requirements if safety certification is mandatory. Check for RoHS and REACH status updates as the component may be subject to lifecycle changes. Ensure I2C address configuration aligns with system design constraints before procurement.

Current Regulation/Management Selection Notes

Select this component when quad-channel power protection with high current capability (up to 600mA) is required. Choose based on the need for ASIL D functional safety compliance and detailed diagnostic feedback via I2C. Consider the 3V-15V input range compatibility with camera supplies. Evaluate the small 4mm x 4mm package size for space-constrained PCB layouts.

Current Regulation/Management Part Context

The MAX20089 is part of the MAX20086–MAX20089 series of dual and quad camera power protectors. This family offers scalable channel counts and consistent protection features across variants. The series is designed for automotive and industrial camera applications requiring robust power management and safety integrity levels.

Current Regulation/Management Replacement Considerations

Direct substitutes within the same series include MAX20086, MAX20087, and MAX20088, depending on the required number of channels. Verify pinout and electrical specifications match exactly. No cross-model generic features should be assumed without verifying specific datasheet parameters for each variant.
