MAX20087ATPA/VY+

Current Regulation/Management Overview

The MAX20087ATPA/VY+ is a camera power protection IC from the MAX2008x series, designed for radar and camera module coaxial cable powering. It provides up to four output channels, each delivering a load current of 600mA. The device operates with an input supply voltage range of 3V to 15V and a service supply voltage of 3V to 5.5V. Key electrical specifications include a typical dropout voltage of 110mV at 300mA, a current limit accuracy of ±8%, and a shutdown current of 0.3μA. It features adjustable current limits ranging from 100mA to 600mA, soft-start time of 0.5ms, and soft-shutdown time of 0.25ms.

Current Regulation/Management Feature Summary

• Provides comprehensive power protection including battery short-circuit isolation, overcurrent limiting, and thermal shutdown for each output channel.
• Integrates an on-board ADC and I2C interface for independent monitoring of current, output voltage, and power status across all channels.
• Supports diagnostic functions such as VBAT/GND short detection, differential output over/under-voltage detection, and input over/under-voltage detection.
• Complies with ASIL B/D safety standards and AEC-Q100 automotive qualification requirements.

Current Regulation/Management Applications

• Radar module coaxial cable powering
• Camera module coaxial cable powering
• Automotive imaging systems

Current Regulation/Management Procurement Notes

Verify the specific suffix 'ATPA/VY+' to confirm the tape-and-reel packaging and temperature grade. Confirm that the required I2C address configuration matches your system design, as addresses are selectable. Ensure the host controller supports the necessary digital interface for reading diagnostic data via the onboard ADC.

Current Regulation/Management Selection Notes

Select this component when multi-channel power protection with high precision is required for camera or radar applications. The adjustable current limit allows customization for different load requirements up to 600mA per channel. The small 4mm x 4mm package is suitable for space-constrained designs. Consider the ASIL compliance if functional safety certification is mandatory for the application.

Current Regulation/Management Part Context

The MAX20087ATPA/VY+ belongs to the MAX2008x family of camera power protection ICs. This series includes variants with two or four channels, offering similar protection and diagnostic features. The MAX2008x devices are specifically engineered to handle the robustness requirements of automotive camera and radar modules, providing reliable power distribution and fault management in harsh environments.

Current Regulation/Management Replacement Considerations

Check for other members of the MAX2008x family, such as MAX20086 or MAX20088, which may offer different channel counts or pin configurations. Verify compatibility with existing PCB layouts and software drivers when substituting with related parts.
