Classification: CPC H | IPC H

Claim 9:
10. An integrated circuit, comprising:
an input voltage terminal;
a battery terminal;
monitoring circuitry coupled to the battery terminal and configured to detect a transient fault condition of a battery charge operation of the integrated circuit;
a power stage coupled between the input voltage terminal and the battery terminal, the power stage having a power switch; and
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 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.
