Product details

130 mOhm low-side switch for 1.8 A loads

It delivers up to 1.8 A continuous output with a typical on-resistance of 130 mOhm, switching loads up to 35 V. The input is non-inverting, and the switch operates without a Vcc supply — the gate drive is self-biased from the load voltage.

Fault protection and temperature range

Fixed current limiting and over-temperature shutdown are integrated, so no external sense resistor or thermal monitor is needed.

Obsolete — sourced to order

The IPS021 is listed as obsolete.

Frequently asked questions

Is the IPS021 compatible with 3.3V or 5V logic?

The IPS021 input is non-inverting and the switch does not require a Vcc supply — the gate is driven from the load voltage. Logic compatibility depends on the input threshold relative to the load rail; the datasheet should be consulted for the exact turn-on threshold.
