Get Started with the FRDM33772BTPLEVB

This page will assist you in learning about your FRDM33772BTPLEVB board.

2. Get to know the hardware

2.1 Board description

The FRDM33772BTPLEVB serves as a hardware evaluation tool in support of NXP's MC33772B device. The FRDM33772BTPLEVB is an ideal platform for rapid prototyping of MC33772B-based applications that involve current, voltage and temperature sensing.

The FRDM33772BTPLEVB includes a transformer enabling communication in a high- speed isolated communication network. The information is digitally transmitted to a microcontroller for processing.

2.2 Board features

  • Daisy chain device connection
  • LED indicator for operation mode
  • Cell-balancing resistors
  • Cell sense input with RC filter
  • GPIO: digital I/O, wake-up inputs, convert trigger inputs, ratiometric analog inputs, analog inputs with absolute measurements
  • EEPROM (connected to the IC with I2C interface) to store user-defined calibration parameters
  • Fault detection pin report
  • Current measurement input via external shunt

2.3 Board components

Overview of the FRDM33772BTPLEVB evaluation board


2.4 Additional board support

Refer to FRDM33772BTPLEVB, evaluation board user manual for additional details on the featured components.

3. Configure the hardware

3.1 Battery stack connection

A minimum of 3 cells and a maximum of 6 cells can be monitored. NXP provides a 6- cell battery emulator board, BATT-6EMULATOR. This board provides an intuitive way to change the voltage across any of the 6 cells of an emulated battery pack as well as the voltage across an emulated current sense shunt resistor. In addition, a battery pack (BATT-14AAAPACK) using AAA batteries is available to support FRDM33772BTPLEVB.


3.2 TPL communication connection

In a high-voltage Isolated application with a daisy chain configuration, up to 15 FRDM33772BTPLEVB boards may be connected.

The TPL connections use the COMM (J4) connector.


3.3 Fault chain connection

The FAULT chain connection is optional. When used, it connects through the FAULT (J3) connector.


3.4 Additional board support

Refer to FRDM33772BTPLEVB, evaluation board user manual for additional details on the hardware configuration.
