1. Out of the Box

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 guides you through the process of setting up and using the PACK-BJBEMUL board.

2.1 Kit Overview

NXP provides battery junction box (BJB) integrated circuits (for example, the MC33777A). The PACK-BJBEMUL emulates different elements of a BJB (for example, high voltage, battery current, pyrotechnic switch) to ease the evaluation of the BJB devices.

This section describes the typical setup to configure the PACK-BJBEMUL to evaluate the RDA777T2 reference design.

The RDA777T2 can measure the emulator current, voltage and temperature. It can also trigger the pyrotechnic switch emulation circuitry.

The setup shows a KIT-PC2TPLEVB board to interface the RDA777T2 with the computer via NXP software tools (for example, battery management system (BMS) ScriptGUI).
