Analog Devices Inc. MAX2008x Camera Power Protect ICs
Analog Devices Inc. MAX2008x Camera Power Protect ICs are dual/quad-camera protector ICs that deliver up to 600mA load current to each of the four output channels. These ICs operate from a 3V to 5.5V supply with a 3V to 15V camera supply and an input-to-output voltage drop of 110mA (typical) at 300mA. The MAX2008x ICs offer an enable input and I2C interface to read the diagnostic status of the device. The ICs feature an onboard ADC that allows reading of the current through each switch. The MAX2008x camera power ICs include overtemperature shutdown and overcurrent limiting on each output channel separately. The ideal application for the power protect ICs includes power-over-coax for radar and camera modules.Features
