The S-8252AAU-M6T1U battery management integrated circuit (IC) is an integrated power management IC for Li-ion batteries with two independent power channels. It provides a variety of functions for Li-ion battery operating, including overload protection, overcharge protection, undervoltage protection, and temperature monitoring. The S-8252AAU-M6T1U is a highly integrated solution that enables control of the charging and discharging process of the battery in portable devices such as smartphones, tablets, and laptops.

The S-8252AAU-M6T1U IC is suitable for a wide range of Lithium-ion battery-based applications, including portable medical equipment, digital cameras and camcorders, wearable electronics, and other devices that require Li-ion battery management.

The S-8252AAU-M6T1U IC contains two independent battery charging channels and two independent battery discharging channels. It also provides three LED control modes to indicate the battery’s charging, discharging and fault status. The charge control circuit uses a constant voltage/constant current charging algorithm to maximize the battery life. The device is designed to meet the requirements of USB PD (Power Delivery) and QC (Quick Charge) chargers. Additionally, it supports power bank applications by providing a DC/DC converter function.

The S-8252AAU-M6T1U IC’s charging and discharging channels are each controlled by an independent voltage comparator with a hysteresis voltage. The device also has overcurrent protection with a user-programmable trip point and can automatically switch off if the battery voltage exceeds or drops below the user-set limits. It also has two analog-to-digital converters for monitoring the battery voltage and current. The voltage of each channel is monitored by two Schottky-type diodes, making the IC suitable for operation over temperature range between -40°C to 85°C.

The S-8252AAU-M6T1U IC is capable of sustaining up to a maximum charge current of 1.5A and a maximum discharge current of 0.05A. In addition, the device provides a power path control (PPC) function, which allows the device to be used as a current mirror to power the charging and discharging channels independently. This allows the device to be connected to external cooling devices, such as fans and heat sinks, to reduce the operating temperature.

In addition, the S-8252AAU-M6T1U IC includes several features to ensure safety and reliability, such as built-in safety timers for overcharge and overdischarge events, low junction temperature alert, overvoltage and low voltage protection, and over-current protection.

The S-8252AAU-M6T1U IC is an ideal solution for battery management in a wide range of mobile and portable applications. The IC supports a wide range of features and functions, enabling efficient and safe management of Li-ion batteries. It also supports high current operation, making it suitable for use in high-power applications. With its small package size, the S-8252AAU-M6T1U is suitable for use in space-constrained applications. Finally, its low power dissipation, integrated safety features, and wide operating temperature range make it an ideal choice for portable devices that require reliable and efficient battery management.
