LC706203CM

Microphones Overview

The LC706203CM is a smart battery gauge IC designed for lithium-ion and lithium-polymer batteries. It integrates an analog-to-digital converter (ADC) to measure cell voltage, current, and temperature. The device calculates state of charge (SOC), remaining capacity, and time-to-empty using on-chip algorithms. It communicates via I2C interface. Key parameters include a supply voltage range of 2.4V to 5.5V, operating temperature from -40°C to +85°C, and accuracy specifications for voltage measurement typically within ±1.5mV and current measurement dependent on the external shunt resistor.

Microphones Procurement Notes

Verify the specific suffix 'CM' indicates the correct package type and tape/reel configuration required for your assembly process. Confirm that the component version matches the datasheet revision for intended algorithm behavior. Ensure compatibility with your system's I2C address settings and voltage levels before procurement.

Microphones Selection Notes

Select this component when a compact, integrated solution for fuel gauging is needed without external EEPROM. Consider the required accuracy for voltage and current sensing relative to the external shunt resistor selection. Evaluate the I2C speed requirements and ensure the host processor supports the necessary communication protocol for reading SOC and health data.

Microphones Part Context

This part belongs to onsemi's family of smart battery management solutions. It is designed to replace discrete sensor and microcontroller combinations in space-constrained portable electronics. The integration reduces bill of materials cost and board space while providing reliable battery status information to the host system.

Microphones Replacement Considerations

Check for direct pin-compatible alternatives within the same product family if different package options are needed. Verify that any substitute maintains the same I2C command set and algorithm characteristics to avoid software revalidation.
