NXP Semiconductors RD33771CDSTEVB Evaluation Board

NXP Semiconductors RD33771CDSTEVB Evaluation Board provides an easy-to-use platform for evaluating the MC33771C 14-channel battery cell controller for automotive and industrial Li-ion battery applications. The device performs ADC conversion on the differential cell voltages/currents and is capable of counting battery charge coulomb and temperature measurements. The RD33771CDSTEVB eval board includes a transformer that enables communication in a high-speed isolated communication network. The information is digitally transmitted to a microcontroller for processing. This board can be used with a transceiver physical layer transformer driver (MC33664) to convert MCU SPI data bits to pulse bit information for the MC33771C and vice versa. NXP RD33771CDSTEVB Evaluation Board is ideal for rapidly prototyping MC33771C-based applications that involve current, voltage, and temperature sensing.
