Abstract
Overcurrent detector and method for a charging path of a charge pump. For example, an overcurrent detector for a charging path of a charge pump, the charging path including a switch associated with a switch on-resistance value, the charge pump being configured to receive an input voltage and generate an output voltage to charge a battery, the overcurrent detector including: a reference unit biased to the output voltage and configured to generate a reference voltage representing a predetermined threshold current for the switch of the charging path; a detection unit coupled to the reference unit and configured to generate a sensing voltage representing a charging current that flows through the switch of the charging path; and an output unit configured to generate an over-current-protection signal based at least in part on the reference voltage and the sensing voltage.
