お客様の BMA7118 Evaluation Board with Isolated Daisy Chain
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 (ICs) 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 EVBMA7118DT board.
1.1 Kit Content and Packing List
The EVBMA7118DT contents include:
- Assembled and tested EVBMA7118DT board in an antistatic bag
- Transport protocol link (TPL) cable
- Battery emulator connector cable

2.1 Board Features
The board implements a resistive divider to allow evolution of the analog front-end (AFE) without cell emulators and also features:
- The option to connect to the BATT-18EMULATOR or real cells
- The option to connect cell 0 to an external stimulus
- Easy access to general-purpose input/output (GPIO) pins
- An operation mode indicator
- Components assembly only on the top side
- A compact design
- Minimized bill of materials (BOM)
2.2 Board Description
The EVBMA7118DT is a battery monitor evaluation board using one BMA7118. The BMA7118 is an 18-cell AFE integrated circuit (IC). The board includes the necessary auxiliary components to operate the BMA7118.
The EVBMA7118DT can be supplied with a DC laboratory power supply. Alternatively, the board can be connected to the BATT-18EMULATOR or even real battery cells.
3. Configure Hardware
Figure 2 shows a complete setup. The setup uses the BATT-18EMULATOR to supply and emulate the cell voltages for two EVBMA7118DT boards. The KIT-PC2TPLEVB enables communication with a regular PC. The evaluation graphical user interface (GUI) displays the measured voltages and allows interaction with the BMA7118 devices. Depending on the scope of evaluation, the evaluation system can be altered to use different components (for example, real battery cells or a different TPL communication source).
