MAX20086

Dual/Quad Camera Power Protector

Industry's Only ASIL-Grade Camera Protector with integrated I2C-Based Diagnostics


Please check latest availability status for a specific part variant.

Description

The MAX20086–MAX20089 dual/quad camera power protector ICs deliver up to 600mA load current to each of their four output channels. Each output is individually protected from short-to-battery, short-to-ground, and overcurrent conditions. The ICs operate from a 3V to 5.5V supply and with a 3V to 15V camera supply. The input-to-output voltage drop is only 110mV (typ) at 300mA.

The ICs provide an enable input and I2C interface to read the diagnostic status of the device. An on-board ADC enables reading of the current through each switch. The ASIL B- and ASIL D-compliant versions include support for reading an additional seven diagnostic measurements through the ADC, ensuring high-fault coverage.

The MAX20086–MAX20089 include overtemperature shutdown and overcurrent limiting on each output channel separately. All devices are designed to operate from -40°C to +125°C ambient temperature.
