Datasheet
The Altera® Enpirion® ES1010SI is a fully featured hot-swap
power controller that targets +12V applications. The
ES1010SI has an integrated charge pump, which can generate
a higher (6.5V) gate drive to improve efficiency.
This IC features programmable overcurrent (OC) detection,
current regulation (CR) with time delay to latch-off and soft-
start.
The current regulation level is set by 2 external resistors;
R_ISET- sets the CR Vth and the other is a low ohmic sense
resistor across, which the CR Vth is developed. The CR
duration is set by an external capacitor on the CLTIM pin,
which is charged with a 20µA current once the CR Vth level is
reached. The IC then quickly pulls down the GATE output
latching off the pass FET.
