The RD33771CDSTEVB 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 and GPIOs. The kit is designed to support customer development and evaluation. The device can be connected to NXP's 14-cell battery emulator or a customer Li-ion battery module with 7~14 logic cells in series. Up to 63 RD33771CDSTEVB 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 the FRDMDUAL33664EVB.
