Product details

Four-channel high-side switch — what the 21 mOhm Rds(on) buys

The BTS5440GXUMA1 is a 4-channel high-side N-channel power switch from Infineon's IntelliSense™ family. Each output is rated for a continuous 5.7 A maximum, and the typical on-resistance of 21 mOhm keeps conduction losses low enough that the 28-SOIC package can dissipate the heat without forced airflow in most 12 V and 24 V loads.

Load voltage and protection — where it fits the BOM

The load supply range spans 4.5 V to 28 V, covering standard automotive and industrial rails but not 3.3 V logic-level loads. Integrated fault protection includes current limiting (fixed threshold), open-load detection, overtemperature shutdown, and overvoltage clamp — four diagnostics that reduce the need for external sense resistors or comparators on each channel.

Obsolete — sourcing strategy for the BOM line

Infineon lists the BTS5440GXUMA1 as obsolete.

Frequently asked questions

Is the BTS5440GXUMA1 obsolete?

Yes, Infineon has classified the BTS5440GXUMA1 as obsolete. There is no official replacement or successor part listed by Infineon.

What package does the BTS5440GXUMA1 come in?
