Claim 0:
1. A system, comprising:
a switching converter circuit adapted to be coupled between an input voltage source and a load; and
an integrated circuit adapted to be coupled between the input voltage source and a battery and configured to charge the battery, the integrated circuit having:
monitoring circuitry adapted to be coupled to the battery and configured to detect a transient fault condition of the integrated circuit;
a power stage adapted to be coupled between the input voltage source and the battery, the power stage having a power switch;
a control circuit coupled between the monitoring circuitry and the power stage, the control circuit including:
a first and second transconductance stage having respective outputs coupled to a control terminal; and
a resistor coupled in series with a capacitor between the control terminal and a ground terminal;
wherein:
the control circuit is configured to provide a control signal on the control terminal to adjust a conductivity of the power switch responsive to a detected transient fault condition; and
the control signal is a function of the resistor, the capacitor, and the respective outputs of the first and second transconductance stages.
