This page will help guide you through the process of learning about your RD33771CDSTEVB board.

2. Get to know the hardware

2.1 Board features

  • Daisy chain device connection
  • LED indicator for operation mode
  • Cell-balancing resistors
  • Transformer isolation
  • Cell sense input with RC filter
  • GPIO: digital I/O inputs, wake-up inputs, convert trigger inputs, ratiometric analog inputs, analog inputs with absolute measurements

2.2 Board description

The RD33771CDSTEVB serves as a hardware evaluation tool in support of NXP's MC33771C device. The RD33771CDSTEVB is an ideal platform for rapid prototyping of MC33771C-based applications that involve current, voltage and temperature sensing.

The RD33771CDSTEVB includes a transformer enabling communication in a high- speed isolated communication network. The information is digitally transmitted to a microcontroller for processing.

2.3 Board components

Overview of the RD33771CDSTEVB: High voltage Lithium-ion battery management system reference design with transformer isolation.


2.4 Additional board support

Refer to UM11343, RD33771CDSTEVB reference design for additional details on the featured components.

3. Configure the hardware

3.1 Battery emulation connection

A minimum of 7 cells and a maximum of 14 cells can be monitored. NXP provides a 14- cell battery emulator board, BATT-14CEMULATOR. This board provides an intuitive way to change the voltage across any of the 14 cells of an emulated battery pack and four voltage outputs to emulate four external NTC. The emulator board can be connected to the RD33771CDSTEVB connector J1 using the provided supply cable.


3.2 TPL communication connection

In a high-voltage Isolated application with a daisy chain configuration, up to 63 RD33771CDSTEVB boards may be connected. The TPL connections use the COMM connectors (J2, J3).


3.3 Additional board support

Refer to UM11343, RD33771CDSTEVB reference design user manual for additional details on the hardware configuration.

3.4 Ready to use
