The FRDM33771CSPEVB evaluation board (EVB) features the MC33771C, 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 current measurement.
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. The battery cell information is transferred to the microcontroller unit (MCU) through an SPI interface.
