Product Details

The MAX20480 evaluation kit (EV kit) is a fully assembled and tested application circuit for the MAX20480 seven-input automotive power-supply monitor. The test-point taps allow for routing to other subsystems for monitoring. Connectors are provided for I²C communication.

The MAX20480 EV kit can also evaluate the MAX20481 IC. Simply replace the installed MAX20480 with the MAX20481 IC.

The MAX20481 does not have an I²C interface, so there is no requirement for the MINIQUSB+.

Applications

ADAS
Autonomous Driving Processing Systems
Power System Supervision and MCU/SoC Monitoring
Remote Sensor Modules
