MAX20089ATPB/VY+T

Current Regulation/Management Overview

The MAX20089ATPB/VY+T is a quad camera power protector IC from the MAX20086–MAX20089 family, manufactured by Analog Devices Inc./Maxim Integrated. It delivers up to 600mA load current to each of its four output channels and operates from a 3V to 5.5V device supply with a 3V to 15V camera supply input. The device features ±8% current-limit accuracy, an I2C interface for diagnostic status reading, and an on-board ADC for individual channel current monitoring. It includes overtemperature shutdown and overcurrent limiting on each output channel separately, ensuring high fault coverage in safety-critical applications.

Current Regulation/Management Feature Summary

• Provides independent short-to-battery, short-to-ground, and overcurrent protection for four output channels
• Includes an I2C interface and on-board ADC for real-time diagnostic status and current measurement
• Features adjustable current limits ranging from 100mA to 600mA per channel
• Designed for ASIL B and ASIL D compliant automotive safety applications

Current Regulation/Management Applications

• Power-over-coax systems for radar modules
• Quad camera module power distribution
• Automotive infotainment and sensor power management
• Safety-critical vehicle electronics requiring high fault coverage

Current Regulation/Management Procurement Notes

Verify the specific suffix PB/VY+T against the official datasheet to confirm package type and RoHS compliance. Ensure the ordering code matches the exact pinout and thermal pad configuration required for your PCB layout. Cross-reference the manufacturer's latest documentation to confirm availability and any potential product changes or obsolescence notices before finalizing procurement plans.

Current Regulation/Management Selection Notes

Select this component when four independently protected power channels are required for camera or sensor arrays. It is suitable for designs needing precise current limiting and detailed diagnostic feedback via I2C. Consider the 20-pin SWTQFN package size and operating temperature range of -40°C to +125°C for environmental compatibility. Verify that the input voltage range supports both the device supply and camera supply requirements of your system architecture.

Current Regulation/Management Part Context

This part belongs to the MAX20086–MAX20089 series of dual and quad camera power protectors. The series offers scalable protection solutions with varying numbers of channels. The MAX20089 specifically provides four channels, making it distinct from the dual-channel variants. All devices in the family share similar diagnostic capabilities and safety features but differ in channel count and package options.

Current Regulation/Management Replacement Considerations

Check for direct substitutes within the MAX20086–MAX20089 family based on channel count requirements. Verify pin-to-pin compatibility if replacing with other Maxim Integrated power protectors. Ensure any alternative part meets the same ASIL B/D compliance and AEC-Q100 qualification standards.
