HVIC^TM

High-Voltage Start-Up IC

Features

Description

The IRS25751 is a 480V high-voltage start-up

IC ideal for supplying initial supply starting current

from a high-voltage bus. The IRS25751 supplies

a constant current during start-up and then

consumes ultra-low standby (off) current.

Additional features include programmability of the

upper turn-off threshold, an ENN input, and over-

temperature protection. IR’s proprietary HVIC

technology provides robust operation from high

input voltage levels with simple yet flexible

features.



Up to 480V voltage capability

Constant output current (4.5mA)

Programmable upper threshold level

Fixed lower threshold (4.2V)

ENN input

Over-temperature shutdown

Ultra-low off current (2.5µA)

Internal 20.8V clamp on VOUT pin

Excellent latch immunity on all inputs & outputs

Integrated ESD protection on all pins

5-pin SOT-23 package
