Infineon Technologies R 48V BATT SWITCH10 Reference Board
Infineon Technologies R 48V BATT SWITCH10 Reference Board demonstrates an implementation of an air-cooled high current protection switch up to 300A for automotive 48V batteries. The design of the R 48V BATT SWITCH10 is based on the two-channel MOSFET gate driver 2ED4820-EM. The two channels provide flexibility for the R 48V BATT SWITCH10 Reference Board. Channel A controls the Power MOSFETs (IAUT300N08S5N011) for (dis-)connecting the battery. Channel B drives the MOSFETs (IAUZ40N10S5N130) for the DC-link pre-charge circuit.The Infineon R 48V BATT SWITCH10 Reference Board offers two diverse methods for current monitoring and overcurrent protection to improve functional safety. These methods are a shunt based on the low-side and core-less hall-based current sensing with the TLE4972-AE35D5 on the high side. The switch is controlled by an XMC4700 microcontroller kit with a USB port.
The R 48V BATT SWITCH10 Reference Board can be configured and operated via a command-line interface.
