Infineon High Side 4, High Side Power Switch Power Switch IC 20-Pin, DSO

This power switch IC is a multi-output high-side switching device designed for automotive control tasks. It integrates four independently controlled channels to manage loads in vehicle systems, operating across a mid-range supply span and intended for surface-mounted applications in electronic modules. The device is suitable where compact packaged high-side switching and regulated output capability are required in automotive environments.

• 4 outputs providing independent channel control and load segregation
• 4 inputs enabling straightforward logic interfacing for each channel
• 5.5-40V supply range allowing operation from common vehicle voltages
• 3.3A output current supporting moderate current actuators and loads
• 180mΩ Rds(on) reducing conduction losses under load
• -40 to 150°C operating range ensuring functionality in harsh climates

• Suitable for body control modules managing lighting loads
• Ideal for driver assistance peripheral power management
• Used with motor drivers for small actuator switching
• Can be used for infotainment power distribution sub-systems
• Appropriate for harnessed ECU assemblies requiring multiple high-side channels

The device presents 20 pins in a compact DSO footprint suitable for surface mounting and standard board routing.

It is rated to function over a wide thermal span from -40°C up to 150°C to accommodate under-bonnet and ambient extremes.

The internal arrangement is a high-side switching topology, placing the switch between supply and load for protected sourcing.

The part is delivered in a DSO package intended for surface-mount assembly, allowing low-profile placement on boards.
