In one embodiment, a circuit is formed to couple a battery to a charging voltage at least a portion of a time when the charging voltage is greater than zero volts and is less than a first voltage value. The circuit is also formed to decouple the battery from the charging voltage approximately when the charging voltage is greater than the first voltage and also approximately when the charging voltage is no greater than zero volts.

Battery protection method and circuit therefor

A voltage regulator () is formed to generate a compensation current to flow when an output voltage of the voltage regulator () exceeds a compensation value. The compensation current is at least equal to the leakage current of the output transistor ().

Method of forming a low quiescent current voltage regulator and structure therefor

An multi-stage error amplifier () of a power management system () is formed to insert a zero to compensate for a high frequency pole that could cause unstable outputs at some output current levels. The error amplifier () includes a feed-forward block () that isolates the capacitor () from other signal paths to facilitate low noise and high efficiency operation.

Power management method and structure

An audio amplifier system ( ) is formed to include a voltage reference ( ). The voltage reference ( ) is formed to utilize a filter having a first cut-off frequency when the output ( ) of the voltage reference ( ) is less than a first value and to use a second cut-off frequency when the output ( ) is greater than the first value.
