HVICTM
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

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to COM, all currents are defined positive into any pin. The thermal
resistance and power dissipation ratings are measured under board mounted and still air conditions.
