FRDM33771BTPLEVB

FRDM33771BTPLEVB evaluation board features 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 6~14 logic cells in series. Up to 15 FRDM3377xBTPLEVB can be connected within a daisy chain. The battery cell information is transferred to MCU through an isolated differential communication bus using FRDM33664BEVB.

• LED indicator for operation mode
• Cell-balancing resistors and integrated drivers
• Cell sense input with low pass filter
• Interface I2C link to an external local EEPROM to store user-defined calibration parameters
• Isolated fault detection pin report
