The MAX20084B is a dual-antenna power supply with an I2C interface for diagnostics and control. The dual 270mA antenna supplies are linear regulators whose output voltage is set individually through I2C. Additionally, internal registers are used to set the current limit, open-load threshold, and other parameters.An internal 8-bit ADC allows the channel current to be measured. The AOUT analog output can also be used with an external ADC to measure the output current on either channel.The MAX20084B is available in two variants: the MAX20084BATEA/VY+ with both channels turned off by default after power-up, and the MAX20084BATEB/VY+ with channel 1 turned on by default after power-up.The MAX20084B is available in a 4mm x 4mm, side-wettable TQFN package and operates over the -40°C to +125°C temperature range.ApplicationsAutomotive Camera and Sensor PowerAutomotive Microphone PowerRemote LNA Phantom Power
