FRDM33771BTPLEVB
Overview
The FRDM33771BTPLEVB is a hardware evaluation platform for the MC33771B lithium-ion battery cell controller. It utilizes NXP's Transformer Physical Layer (TPL) interface to communicate with a battery management system (BMS) controller, enabling high-speed isolated daisy-chain communication. This board is designed to monitor battery cell voltages and temperatures in high-voltage battery packs.
Why Choose This Part
The board provides a direct path to evaluating the MC33771B's 14-cell measurement capability and integrated passive cell balancing. By using the TPL interface, engineers can test robust, isolated communication over long wire harnesses with high electromagnetic compatibility. The Freedom form factor allows for easy interfacing with MCU development boards for full system prototyping.
Applications
Key Specifications
Getting Started
To use this board, connect it to a stack of battery cells (up to 14 cells) or a cell simulator. It requires a TPL-to-SPI gateway, such as the FRDM33664BEVB, to communicate with a host microcontroller like the S32K series. NXP provides a Battery Management System SDK that includes drivers and example code for cell voltage reading and balancing configurations.
