The S-8261ACEMD-G4ET2G is a product developed by Renesas Electronics which is a member of the Renesas Power Management IC (PMIC) series that are often used for power management applications. This particular PMIC provides a range of features for battery management, such as overcharge, overdischarge, over current, and thermal protection for both Li-ion and Li-polymer batteries. It also offers integrated protection circuitry for automated cell balancing, and allows for easy addition or removal of cells from the system.

The S-8261ACEMD-G4ET2G is designed to provide low current stand-by mode to help maximize battery life and reduce power consumption during periods of low activity. Additionally, it also has an input voltage range up to 8 V, admitting up to 8 cells in series.

This PMIC is specially built for single-cell Li-ion and Li-polymer battery applications. It simplifies and reduces costs for high-precision battery applications that require effective protection and advanced features, such as precise voltage measurement. The S-8261ACEMD-G4ET2G has a built-in programmable safety timer that helps cut power to the system in case of overcharge or overdischarge conditions, and a programmable cell balance timer which helps extend battery life.

The S-8261ACEMD-G4ET2G also boasts a precision 4µA current measurement and a high accuracy voltage measurement across 10 bits. It has an integrated switching power-down mode, which works by automatically discharging VDD to VSS and VSS to VBAT levels, respectively, when the input voltage falls below a certain value. This is an important feature that reduces unnecessary power consumption and helps maintain low-power stand-by states.

In terms of safety features, the S-8261ACEMD-G4ET2G offers the highest levels of integration. Its overcurrent protection (OCP) function helps protect the battery from high discharge current and its thermal protection (TP)function helps prevent thermal runaway due to abnormal temperatures or environment conditions. It also features an under-voltage lockout (UVLO) which helps protect from over-voltage and over-temperature conditions.

The S-8261ACEMD-G4ET2G is designed for use in various applications that require effective battery management and power conservation, such as mobile phones, wearables, tablets, consumer electronics and other portable devices. It has a wide temperature range and is very reliable in environments with a temperature range between -40°C and +85°C.

In short, the S-8261ACEMD-G4ET2G is a high-performance PMIC developed by Renesas Electronics and is ideal for battery management applications. It offers robust protection and remarkable accuracy and safety features which makes it a great choice for mobile and other portable applications.
