Product details

Overview

LC709203FXE-01-GEVB from onsemi is an evaluation board for the LC709203FXE-01MH battery fuel gauge IC, designed to validate single-cell Li-ion/polymer battery state-of-charge (RSOC) measurement using the HG−CVR algorithm. It supports thermistor- and I²C-based temperature sensing, delivers ±7.5 mV voltage accuracy and 2.8% RSOC accuracy, and enables rapid prototyping in portable electronics with minimal configuration.

For engineers reviewing the LC709203FXE-01-GEVB datasheet, pinout, applications, or equivalent options, this board provides verified hardware reference for integrating the LC709203F fuel gauge IC into battery management systems requiring aging-aware, sense-resistor-free RSOC tracking under dynamic load and temperature conditions.

Technical Context

The LC709203FXE-01-GEVB implements the LC709203FXE-01MH IC in WLCSP9 package (1.60 × 1.76 mm), interfacing directly to a single Li-ion cell via PACK+ and PACK− terminals. It routes all nine pins-including SDA, SCL, TSENSE, TSW, ALARMB, TEST, VDD, VSS, and exposed pad-to accessible test points and connectors for real-time register access and alarm monitoring.

It supports both thermistor-based temperature acquisition (via TSW/TSENSE with external 10 kΩ thermistor and 100 Ω ESD resistor) and host-provided temperature over I²C (register 0x08). The board includes pull-up resistors for SDA/SCL, configurable ALARMB output, and jumper-selectable power mode (Operational/Sleep) per register 0x15.

Key Specifications

Parameter	Value and Actual Design Meaning
Board Type	Evaluation board for LC709203FXE-01MH fuel gauge IC - not a standalone IC or discrete component.
Target Device	LC709203FXE-01MH in WLCSP9 package (Case 567JH), pin-compatible with LC709203FQH-01TWG (WDFN8).
I²C Interface	Supports up to 400 kHz clock; includes onboard 4.7 kΩ pull-ups on SDA/SCL; compatible with standard I²C master controllers.
Temperature Sensing	Dual-mode: thermistor (TSENSE/TSW) or host-supplied (I²C register 0x08); thermistor B-constant programmable via register 0x06.
Alarm Output	Open-drain ALARMB signal driven by register-configurable thresholds (0x13 for RSOC, 0x14 for cell voltage).
Power Modes	Configurable via I²C register 0x15: Operational mode (3 µA typical, full RSOC tracking) or Sleep mode (1–2 µA, I²C-only).

FAQ

What is the primary function of the LC709203FXE-01-GEVB?

The LC709203FXE-01-GEVB is an evaluation board for the LC709203FXE-01MH fuel gauge IC. It does not perform gauging itself but provides a tested hardware platform to configure, communicate with, and validate the operation of the underlying LC709203F IC-including RSOC calculation, temperature sensing modes, alarm generation, and I²C register access.

Does the LC709203FXE-01-GEVB include the LC709203FXE-01MH IC pre-mounted?

Yes, the LC709203FXE-01-GEVB ships with the LC709203FXE-01MH IC already mounted in its WLCSP9 package. The board exposes all nine pins-including VDD, VSS, SDA, SCL, TSENSE, TSW, ALARMB, TEST, and exposed thermal pad-for direct probing, firmware development, and system-level testing.

How do I configure temperature sensing on the LC709203FXE-01-GEVB?

The LC709203FXE-01-GEVB supports two modes: thermistor-based (default) using TSW/TSENSE with an external 10 kΩ NTC thermistor, or I²C-hosted via register 0x08. To use thermistor mode, connect the thermistor between TSW and TSENSE with a 100 Ω series resistor; set register 0x16 = 0x0001. For I²C mode, write temperature values directly to register 0x08 and set register 0x16 = 0x0000.

What are the power supply requirements for the LC709203FXE-01-GEVB?

The LC709203FXE-01-GEVB operates from the connected Li-ion cell (PACK+ and PACK−), with allowable VDD range of 2.5 V to 4.5 V. No external power supply is needed-the board draws current only from the battery under test. The LC709203FXE-01MH IC consumes 3 µA in operational mode and 1–2 µA in sleep mode.

Can the LC709203FXE-01-GEVB be used to evaluate multiple battery profiles?

Yes. The LC709203FXE-01-GEVB supports two factory-loaded battery profiles selected via register 0x12 (e.g., 3.7 V/4.2 V or 3.8 V/4.35 V). Profile identity is stored in register 0x1A. Users can switch profiles dynamically during operation, enabling validation across different Li-ion chemistries and capacities without hardware changes.
