ES1010SI 12V Hot-Swap Power

Distribution Controllers

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;

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.

Features

• Hot-swap Single Power Distribution Control for +12V

• Overcurrent Fault Isolation

• Programmable Current Regulation Level

• Programmable Current Regulation Time to Latch-Off

• Rail-to-Rail Common Mode Input Voltage Range

• Enhanced Internal Charge Pump Drives N-Channel

MOSFET gate to 6.5V above IC bias.

• Undervoltage and Overcurrent Latch Indicators

• Adjustable Turn-On Ramp

• Protection During Turn-On

• Two Levels of Overcurrent Detection Provide Fast

Response to Varying Fault Conditions

• 1µs Response Time to Dead Short

• Pb-Free (RoHS Compliant)

Applications

• FPGA, DSP, and ASIC power protection

• Power Distribution Control

• Hot Plug Components and Circuitry
