Infineon BTS3800SLHTSA1 Low Side 1, Low Side Power Switch Power Switch IC 5-Pin, SCT595

This power switch IC is a compact low-side switching device designed for automotive environments. It provides controlled low-side switching for multiple channels and is intended for surface-mounted assemblies in vehicle electronic systems operating up to typical automotive voltages. The component is built to function across a wide junction temperature range and supports multi-output switching in confined board real estate.

• Five outputs enable concurrent load switching and simplified wiring
• 4A operating current supports moderate automotive loads
• 0.8Ω on-resistance minimises conduction losses during operation
• Accepts supply up to 5.5V for common automotive control rails
• Withstands temperatures up to 150°C for harsh under-bonnet conditions

• Suitable for switching lamps and solenoids in body control modules
• Ideal for multiplexed actuator control in door systems
• Used with vehicle electronics requiring surface-mounted power switches
• Can be used for low-voltage sensor and auxiliary load management

Use adequate PCB copper around the package to dissipate heat and follow manufacturer thermal pad recommendations to maintain junction temperature under high-duty cycles.

The part provides a single input controlling multiple outputs, enabling simplified logic drive and fewer MCU pins.

Keep supply voltage below 5.5V and ensure no negative excursions beyond -0.3V on input lines to prevent overstress.

Yes, it provides a compact alternative to individual low-side MOSFETs by integrating five switching channels in one surface-mount package.
