Abstract
A cell protection system includes a charge control MOSFET, a charge current detection MOSFET, a discharge control MOSFET, a discharge current detection MOSFET, a charge current detection resistance, a discharge current detection resistance and a control circuit. The charge current detection MOSFET has a drain and a gate common with the charge control MOSFET. The discharge control MOSFET has a drain common with the charge control MOSFET. The discharge current detection MOSFET has a drain and a gate common with the discharge control MOSFET. The resistancesare provided in correspondence to the charge and discharge current detection MOSFETs. The control circuit generates a gate control signal for the charge control and current detection MOSFETs by using one of the resistances and generates a gate control signal for the discharge control and current detection MOSFETsby using another one of the resistances.
