MAX20087ATPA/VY+

MAX20087ATPA/VY+ is a camera power protector IC that delivers up to 600mA load current to each of its four output channels. Each output is individually protected from short-to-battery, short-to-ground, and overcurrent conditions. The IC operates 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 IC provides an enabled input and I2C interface to read the diagnostic status of the device. An onboard ADC enables the reading of the current through each switch. It includes overtemperature shutdown and overcurrent limiting on each output channel separately. The application includes power-over-coax for radar and camera modules.

• 26V short-to-battery isolation, adjustable current limit (100mA to 600mA)
• Parallel multiple channels for higher current, selectable I2C addresses
• ±8% current-limit accuracy, 0.5ms soft-start, autoretry on fault
• Short to VBAT/GND diagnostics, differential output over/undervoltage diagnostics
• Input over/undervoltage diagnostics
• Individual 8bit current, output voltage, and supply readings over I2C
• AEC-Q100 qualified, ASIL B/D compliant
• 20-pin SWTQFN-EP package
• Temperature range from -40°C to +125°C
• On-resistance is 400mohm typical (VDD = 5V, VIN = 6.5V. TA = TJ = -40°C to +125°C)
