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 RDI7018C3T1 board.

2.1 Kit Overview

The RDI7018C3T1 is a hardware evaluation tool supporting the NXP BMI7018 device. The RDI7018C3T1 implements three BMI7018 battery cell controller ICs. The BMI7018 is a battery cell controller that monitors up to 18 Li-ion battery cells. It is designed for use in industrial applications. The device performs analog‑to‑digital conversions on the differential cell voltages. It is also capable of temperature measurements and can forward communication via an I²C-bus to other devices. The RDI7018C3T1 is an ideal platform for rapid prototyping of BMI7018 based applications that involve voltage and temperature sensing.

The RDI7018C3T1 measures the pressure of the battery module using the onboard FXPS7250A4ST1 pressure sensor. The RDI7018C3T1 converts the battery module voltage to 12 V using the TEA1721AT/N1,118 flyback controller, then converts the 12 V to 5 V to supply the pressure sensor.

The RDI7018C3T1 uses inductive isolation for offboard communication. The galvanic isolation for onboard communication is established via capacitors.

3.1 Battery Emulator Connection

One BMI7018 can monitor a minimum of four cells and a maximum of 18 cells. NXP provides an 18‑cell battery emulator board, BATT-18EMULATOR. This board provides an intuitive way to change the voltage across any of the 18 cells of an emulated battery pack. The board RDI7018C3T1 can be connected to an 18‑cell battery emulator board using the connectors J1_1, J1_2 and J1_3 with the provided supply cables; see Figure 2.

3.2 TPL Communication Connection

In a high-voltage isolated application with a daisy chain configuration, up to 21 RDI7018C3T1 boards can be connected.

The TPL connections use the COMM connectors J1 and J2 of the FRDM665SPIEVB and J2_1 and J2_1 of the RDI7018C3T1.
