The FRDM33771BTPLEVB Evaluation Board (EVB) features the MC33771B, a 14-channel battery cell controller for automotive and industrial Li-ion battery applications. It supports cell voltage measurement, passive cell balancing, GPIOs, external EEPROM, and fault detection pin report.
The kit is designed to support customer development and evaluation. The device can be connected to NXP 14-cell battery emulator or a customer Li-ion battery module with 7-14 logic cells in series. Up to 15 FRDM3377xBTPLEVB can be connected within a daisy chain. The battery cell information is transferred to the microcontroller unit (MCU) through an isolated differential communication bus using FRDM33664BEVB.
