The S-8261ABJMD-G3JT2U is a highly advanced battery charging and protection device designed to preserve the longevity and reliability of battery cells. It is classified under PMIC (Power Management Integrated Circuitry) – Battery Management and is suitable for single-cell Li-Ion/Li-Polymer battery applications. The device includes a highly efficient and precise charging circuit with a current up to 1.7A and a charge termination voltage up to 4.32V for short-circuit, over-voltage, over-current and over-temperature protection. It also has a unique feature: when the lower or higher temperature option is set, the battery charging process is automatically disabled, preventing the battery from over-charging and prolonging its lifespan.The S-8261ABJMD-G3JT2U is designed to work with a wide range of devices and can be used in a variety of applications. It is commonly employed in personal mobile devices, wearable products, digital and toy cameras, wireless charging modules, Bluetooth products and external portable power supplies. Additionally, it can be used in other battery-powered applications that require precise current and voltage control.The S-8261ABJMD-G3JT2U device combines several power management functions into one package. It provides constant current / constant voltage regulation, over-voltage protection, over-current protection and reverse-current detection, thermal protection and a variety of other features. It is designed to maximize charge time and current, while minimizing power and energy waste. The device operates in constant current mode by constantly monitoring the voltage drop across the sense resistor and adjusting the charge current accordingly. The device provides a current output up to 1.7A, with a programmed over-current protection level of 1A.The charge termination voltage of the S-8261ABJMD-G3JT2U is up to 4.32V, and it also provides over-voltage, over-current and over-temperature protection. The device can detect overcharging in two ways: by monitoring the ripple current and cell temperature, or by setting a higher threshold for the over-voltage protection circuit. In the case of over-voltage or over-current protection, the charge current is reduced or disabled and the charging process is stopped until the charger is removed.The S-8261ABJMD-G3JT2U has two dedicated pins for its thermal sensing: one in the main charging loop for over-temperature protection, and one in the battery pilot loop for temperature-monitoring. These pins are sensitive enough to detect even minimal variations in temperature and provide efficient protection. The device also features a reverse current detection circuit, which prevents current draining from the battery during insertion or removal of the charger.The S-8261ABJMD-G3JT2U comes with a wide range of configuration options, allowing the user to fine-tune the device for specific requirements. The device offers adjustable parameters, such as charging current, charge termination voltage, reset time, sleep mode and over-voltage protection. Additionally, the device is also equipped with a WDT (watchdog timer) event timer to ensure that continuous operation is maintained.Overall, the S-8261ABJMD-G3JT2U is a versatile and highly efficient battery charging and protection devicethat is perfect for a wide variety of applications. Thanks to its low power consumption, adjustable parameters, over-voltage protection, over-current protection and over-temperature protection, the S-8261ABJMD-G3JT2U is a must-have for any Li-Ion or Li-Polymer battery-powered application.
