The document introduces the features and characteristics of the SC806 lithium battery charger produced by semtech. The charger adopts a fully integrated design, single cell lithium battery constant current/constant voltage charging, supports a variety of application scenarios, input voltage range 3V to 6V, and supports 0.1 microamps of discharge current, providing a variety of protection mechanisms
The SC806 is a miniature high current lithium-ion battery charger designed for use as a stand-alone unit or with a Power Management Controller (PMIC). It features a fully integrated design including an FET pass transistor, reverse-blocking diode, sense resistor, and thermal protection. The device supports programmable pre-charge, fast charge, and termination currents with high accuracy.
