The MAXREFDES1277 reference design enables quick evaluation of MAX17853/52 for battery management in a 48V system. It can be used to test IC capabilities such as measurements, cell balancing and alerts using UART and SPI communications.
Hardware Set Up
- MAX17841EVKIT board
- Battery test jig (Battery pack)
- General purpose micro controller (Arduino Mega 2560) for configuring and communication
- Communication cables and Jumper wire
The hardware connections for MAXREFDES1277 (MAX17852/53) with MAX17841EVKIT, battery test jig is shown in image below.
