Getting Started with the KIT33772CTPLEVB Evaluation Board

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 KIT33772CTPLEVB evaluation board.

2.1 Board description

The KIT33772CTPLEVB serves as a hardware evaluation tool in support of NXP's MC33772C device. The MC33772C is a battery cell controller that monitors up to 6 lithium-ion battery cells. It is designed for use in both automotive and industrial applications. The device performs ADC conversion on the differential cell voltages and currents. It is also capable of battery charge coulomb counting and battery temperature measurements.

The KIT33772CTPLEVB is an ideal platform for rapid prototyping of MC33772C-based applications that involve current, voltage, and temperature sensing. 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 MC33772C and vice versa.

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
Current measurement input via external shunt

Configuring the hardware

The KIT33772CTPLEVB kit is designed for use with the FRDMDUAL33664EVB in high- voltage isolated applications that provide a SPI-to-high-speed isolated communication interface. The FRDMDUAL33664EVB includes two MC33664 isolated network high speed transceivers allowing loopback connection. MCU SPI data bits are directly converted to pulse bit information.

3.1 Battery stack connection

The KIT33772CTPLEVB supports the use of a battery cell emulator such as the BATT-6EMULATOR board and BATT-14AAAPACK from NXP.

The BATT-6EMULATOR is a six-cell battery emulator board that provides an intuitive way to change the voltage across any of the six cells and four voltage outputs in order to emulate four external NTCs.

The emulator board can be connected to the KIT33772CTPLEVB J12 connector using the provided supply cable.

To utilize the KIT33772CTPLEVB in combination with the BATT-6EMULATOR, a graphical user interface is available at https://www.nxp.com/webapp/Download?colCode=KIT3377xC_APPSP&appType=license.

3.2 TPL communication connection

In a high-voltage Isolated application with a daisy chain configuration, up to 63 KIT33772CTPLEVB boards may be connected.

The TPL connections use the COMM connectors, J8 and J9.
