Product details

19 mOhm high-side switch for 3.5 A loads

It operates from a 5.5 V to 18 V load supply and requires no Vcc/Vdd bias — the gate drive is self-supplied from the load rail.

Integrated fault protection with auto-restart

The switch integrates fixed current limiting, open-load detection, and over-temperature shutdown. When a fault condition clears, the auto-restart feature re-enables the output without external intervention — a useful behaviour for remote or sealed assemblies where manual reset is impractical. The input is non-inverting with a simple On/Off interface, and the output configuration is high-side with a 1:1 input-to-output ratio.

Buyers should validate pin-compatibility and electrical ratings against any proposed substitute before committing the BOM line.

Frequently asked questions

Does IPS5451STRL have overcurrent protection?

Yes, the IPS5451STRL includes fixed current limiting as part of its integrated fault protection, along with open-load detection and over-temperature shutdown.

What is the Rds(on) of IPS5451STRL?

The typical on-resistance is 19 mOhm. This value is specified at 25 °C junction temperature; actual Rds(on) increases with temperature per the normalised curve in the datasheet.

What package does IPS5451STRL use?

The IPS5451STRL is supplied in a D²Pak-5 (TO-263-5) surface-mount package with four leads plus the tab, also designated as the SMD-220 5-lead. It ships in Tape & Reel.
