LC709204FXE-01TBG

The LC709204FXE-01TBG from ON Semiconductor is a Battery Fuel Gauge LSI designed for 1-cell Lithium-ion/Polymer batteries. It utilizes the unique HG-CVR2 algorithm to provide accurate Relative State Of Charge (RSOC) measurements, even under varying battery conditions such as temperature changes, aging, and self-discharge. This accuracy contributes to reliable operating time estimations for portable devices.

The device supports immediate battery measurement upon parameter setting after battery insertion, eliminating the need for complicated learning cycles often required in manufacturing. It also enhances battery safety with alarm functions and State of Health (SOH) reporting. The low operational current makes it suitable for power-sensitive applications like wearables and IoT devices.

Key features include the HG-CVR2 algorithm for stable and accurate gauging, low power consumption, and support for battery safety alarms. The IC operates over a temperature range of -40°C to 85°C and features an I2C interface for communication. It is supplied in a compact 12-WLCSP package suitable for surface mounting.

Applications for the LC709204FXE-01TBG include wearables, IoT devices, smartphones, digital cameras, portable game players, and USB-related devices. The LSI supports battery lifetime measurement, remaining time estimation, and includes inputs for sensing temperature via NTC thermistors.
