MAX20084

Automotive Dual-Antenna Power Supply with I2C Serial Interface

Dual Antenna Phantom Supply Provides Diagnostics for Multiband Antenna Systems programmable via I2C


Please check latest availability status for a specific part variant.

Description

The MAX20084 is a dual-antenna power supply with 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 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 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 MAX20084 is available in a 4mm x 4mm side-wettable TQFN package and operates over the -40 to +125°C temperature range.
