INTEGRATED CIRCUIT CHARGE PUMP WITH FAILURE PROTECTION

摘要

Disclosed is a charge pump protection device including a power supply voltage, a charge pump to produce an output voltage higher than the power supply voltage, the charge pump including, a pumping capacitor to store voltage during a charging state and to discharge the voltage during a pumping state thereof, a plurality of switches to regulate the charging and pumping states, a charge pump capacitor to store the output voltage, and at least one current limiter in series with at least one of the plurality of switches to limit current and prevent an electrical failure of the charge pump.
