Board overview
The KIT33771TPLEVB evaluation board serves as a hardware evaluation tool in support of NXP’s MC33771 device. The MC33771 is a
battery cells controller that accommodates up to fourteen lithium-Ion batteries. It is designed for use in both automotive and industrial
applications. The device performs ADC conversion on the differential cell voltage and currents. It is also capable of battery charge coulomb
counting and battery temperature measurements.The KIT33771TPLEVB evaluation board is an ideal platform for rapid prototyping of
MC33771-based applications that involve current, voltage, and temperature sensing.
The KIT33771TPLEVB includes a transformer enabling communication in a high speed isolated communication network. The information
is digitally transmitted to a microcontroller for processing. The evaluation board can be used in conjunction with a transceiver physical
layer transformer driver (MC33664) to convert MCU SPI data bits to pulse bit information for the MC33771.
