MAXIM MAX20089ATPB/VY+T

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. The MAX20086–MAX20089 ICs are 2-/4-channel high-side isolation/protection switches with internal current limiting and diagnostics. The input supply range is from 3V to 15V, while the output can tolerate up to 26V. Each output has an accurate current limit of ±8% to protect the input supply from overload and short-circuit conditions.
