MAX20084B Automotive Dual-Antenna Power Supply with 2 I C Serial Interface General Description Benefits and Features The MAX20084B is a dual-antenna power supply with Wide Input Voltage Range: 4.5V to 28V (40V Load 2 an I C interface for diagnostics and control. The dual Dump Tolerant) 270mA antenna supplies are linear regulators whose out- High Integration 2 put voltage is set individually through I C. Additionally, in- Complete 2-Channel Solution with Linear ternal registers are used to set the current limit, open-load Regulators and Diagnostics 2 threshold, and other parameters. I C Control for Minimum Parts Count An internal 8-bit ADC allows the channel current to be Complete and Flexible Control measured. The AOUT analog output can also be used Regulator Output Voltage with an external ADC to measure the output current on ei- Regulator Current Limit ther channel. Regulator Overcurrent Level Individual Disable/Enable The MAX20084B is available in two variants: the MAX20084BATEA/VY+ with both channels turned off by Detailed Diagnostics default after power-up, and the MAX20084BATEB/VY+ Output Current with channel 1 turned on by default after power-up. Short-to-Ground/Battery Overtemperature Warning The MAX20084B is available in a 4mm x 4mm, side- Thermal Shutdown wettable TQFN package and operates over the -40C to +125C temperature range.
