Introduction
The ITS42k5D-LD-F demo board can be used to easily evaluate the dual channel high-side smart switch in the
very small and thermally optimized PG-TSON-10 package. The ITS42k5D-LD-F demo board is fully equipped with
external components as well as the device.
This demo board user’s guide contains all necessary information for using of the this board to evaluate the
ITS42k5D-LD-F.

General Description
The ITS42k5D-LD-F is a dual channel high-side PMOS power switch. The device is equipped with integrated
protection and diagnostic features.
The diagnosis can be read out from two separate open drain outputs in order to indicate overload, short circuit,
open load and overtemperature conditions. The device controls the respective channel one or two by the two
separate input pins i.e. IN1 and IN2. When both inputs are low the device is in OFF condition. Each channel of the
device is able to drive loads up to 250mA.
The ITS42k5D-LD-F is capable of switching resistive, capacitive and inductive loads (e.g. sensor units, LEDs,
relays, valves) in harsh industrial environments. An integrated freewheeling diode per channel enables driving of
inductive loads as well as long wire lengths.
For more detailed information please refer to the datasheet and application notes for the device available on the
Infineon website www.infineon.com.
