Analog Devices / Maxim Integrated MAX20084 Automotive Dual-Antenna Power Supplies

Analog Devices MAX20084 Automotive Dual-Antenna Power Supplies have an I²C interface for diagnostics and control. The MAX20084 Dual 270mA Antenna Supplies are linear regulators whose output voltage is set individually through I²C. Additionally, internal registers are used to assess the current limit, open-load threshold, and other parameters.

The ADI MAX20084 Automotive Dual-Antenna Power Supplies feature an internal 8-bit ADC that allows the channel current to be measured. The A_OUT analog output can also be used with an external ADC to measure the channel’s output current.

The MAX20084 is available in two variants; the MAX20084ATEA/VY+ with both channels turned off by default after power-up, and the MAX20084ATEB/VY+ with channel 1 turned on by default after power-up.

The Analog Devices MAX20084 Automotive Dual-Antenna Power Supplies operates over the -40 to +125°C temperature range and is available in a 4mm x 4mm, optional side-wettable TQFN package.
