The PMIC can detect overcharge, overdischarge, overcurrent, and overheating conditions, providing efficient and reliable battery safety.

The device is designed to efficiently convert a wide input range (2.7V to 5.5V) into three adjustable output voltages (Vout1, Vout2, and Vout3). It also features a battery balancing module with adjustable balancing completion point and an adjustable timer. The device has integrated SOI protection and works with a 3.0mA charge current. The S-8252ABC-M6T1U has a low quiescent current of less than 5.0μA in sleep mode, further improving battery efficiency.

The S-8252ABC-M6T1U\'s key features come with a variety of protective functions. With a charging detection voltage at 4.2V, the device can detect battery overvoltage conditions and will shut off the charge current automatically to avoid damages to the battery when the voltage is over 4.3V. It also includes flow-through discharge protection, allowing the battery to be discharged up to the low-voltage detection voltage. Over-current protection protects the battery from damage if the charging current exceeds the set limit. The device also features OTP (over temperature protection) and over-discharge protection, which shuts the device off if the voltage drops lower than the set threshold.

The S-8252ABC-M6T1U PMIC features an embedded Coulomb counter for measuring the total charge passing through the input terminal. This allows for SOC monitoring, enabling end users to properly power their applications in the most battery-efficient manner. It also has a boosting function that can boost the battery voltage from 3.2V to 4.2V if it drops below 3.2V. The booster can also be adjusted to a higher voltage output depending on the application\'s needs.

The S-8252ABC-M6T1U PMIC supports multiple operating modes. It can detect Li-ion batteries using CV/CC charging or a constant current/voltage combination, as well as other chemistries using a constant voltage approach. It also features an adjustable charging timer, a precision ADC for monitoring battery voltage, and a current monitoring circuit.
