1. Get Started
The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost and improved performance in powering state-of-the-art systems.
This page will guide you through the process of setting up and using the FRDM33772BTPLEVB evaluation board.
1.1 Kit Contents/Packing List

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.
3. Configure 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
3.3 Fault Chain Connection
The FAULT chain connection is optional. When used, it connects through the FAULT (J3) connector.
