Abstract
A circuit to control the slew rate of charging a capacitance using the capacitance is disclosed. An example circuit includes a regulator circuit to regulate a supply voltage during a normal operation mode of the circuit. A capacitance circuit is coupled to the regulator circuit. The regulator circuit is coupled to charge a capacitance between a first node and a second node of the capacitance circuit with a charge current. A slew rate control circuit is coupled to the regulator circuit and the capacitance circuit. The slew rate control circuit sets a slew rate of a voltage between the first and second nodes during a power up mode of the circuit.
