ITS42K5D-LD-F - Infineon Technologies

Overview

The ITS42k5D-LD-F is a 2.5Ω dual channel high-side PMOS power switch including protection and diagnostic functions.

Each channel of the device is able to drive loads up to 250mA. Due to its integrated freewheeling diodes, the ITS42k5D-LD-F is perfectly suitable for driving decentralized loads with long cables or any other kind of inductive loads. The integrated freewheeling diode enables simplified design as no external components are necessary. The ITS42k5D-LD-F is the right product for applications with space constraints as it offers even two channels inside the very small leadless PG-TSON-10 package.
