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 RDA777T2 board.

1.1 Kit Contents and Packing List

  • Electrical transport protocol link (ETPL) communication cable
  • Power supply cable
  • High-voltage measurement cable (orange)
  • Chassis connection cable (black)
  • Two-point general-purpose cable (pyrotechnic switch connection, crash signal connection)
  • Current measurement and temperature measurement cable

1.2 Extra Hardware

The RDA777T2 requires an external +12 V power supply.

The following equipment can also ease the evaluation:

  • ETPL communication board (KIT-PC2TPLEVB)
  • Battery junction box (BJB) emulator to emulate the high voltages, the battery current and the pyrotechnic switch controllers (PACK-BJBEMUL)
  • High-voltage source
  • High-current source coupled with a shunt resistor

3.1 Configure Hardware

This section describes the typical setup to configure the RDA777T2 and to evaluate the MC33777A key features. It uses a PACK-BJBEMUL to emulate the voltages, the battery current and the pyrotechnic switches. Any other external equipment can replace the optional board. The setup shows a KIT-PC2TPLEVB board to interface the MC33777A with the computer via NXP software tools (for example, battery management system (BMS) ScriptGUI).
