SC5510---High-Accuracy Protector with Integrated MOSFET for Single Cell Liion/Polymer Battery
The SC5510F is a highly integrated IC for single-cell Li-ion
battery protection. It controls integrated MOSFET and provides
battery protection functions including battery over voltage
protection and battery under voltage protection,
charge/discharge over current protection and load short circuit
protection etc. The SC5510F only requires little external
components composites of one capacitor and one resistor,
which can reduce space and cost effectively, especially for
limited space battery pack application.
The SC5510F especially integrates compensation for internal
MOSFET Rdson variations under different temperature and
battery voltage, which effectively ensures high-accuracy
voltage/current detection and delay circuit to avoid battery over
charge/ over discharge. Therebefore, battery is applied under
safe region and lifetime is effectively prolonged.
The SC5510F consumes very low standby current for cell longtime storing. The integrated low-Rdson MOSFET ensures that
battery delivers the maximum power.
The SC5510F is available in 8 pin 2x2 DFN(FC) package.
