High-Accuracy Protector with Integrated MOSFET for Single Cell Li-ion/Polymer Battery
PQ5510G
The PQ5510G 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 PQ5510G 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 PQ5510G 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 overcharge/over discharge. Therefore, battery is applied under safe region and lifetime is effectively prolonged. The PQ5510G consumes very low standby current for cell long-time storing. The integrated low-Rdson MOSFET ensures that battery delivers the maximum power. The PQ5510G is available in 8 pin 2x2 DFN (FC) package.
