Description and Operation
The ES1010SI is targeted for +12V single power supply distribution control for generic hot swap switching applications.
This ICs features a highly accurate programmable current regulation (CR) level with programmable time delay to latch-off, and
programmable soft-start turn-on ramp all set with a minimum of external passive components. It also includes severe OC protection
