FRDM33771BSPIEVB

FRDM33771BSPIEVB is an evaluation board for MC33771 with SPI communication features the MC33771, 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. It 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 SPI interface. GPIOs configurable as digital I/O, wake-up input, convert trigger input, ratiometric analogue inputs for external temperature measurement, absolute analogue inputs for external voltage measurements and auxiliary current sense input.

• SPI interface
• LED indicator for the 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
• Fault detection pin report
