Vishay SIP32434ADN-T1E4 High Side 1, Load Switch Power Switch IC 10-Pin, DFN-10

This power switch IC is a multi-channel high-side load switch designed to manage power distribution in compact surface-mounted assemblies. It integrates multiple outputs with a single input to control downstream loads and supports a broad supply range for varied system voltages. The package is optimised for space-constrained designs while supporting elevated operating temperatures for demanding environments.

• 6A continuous current capability enables higher load handling
• 33mΩ Rds(on) reduces conduction losses for improved efficiency
• 2.8V to 23V supply range supports diverse voltage systems
• Five independent outputs simplify multi-rail power control
• Surface mount DFN-10 package enables compact PCB layouts
• Rated to 150°C maximum temperature maintains function under heat

• Suitable for server blade power sequencing and distribution
• Used for multi-rail power control in telecoms equipment
• Ideal for industrial modules exposed to high thermal stress
• Can be used for battery management in portable assemblies
• Used with power-sensitive consumer devices requiring low loss

The device implements high-side switching, allowing loads to be disconnected from the supply rail while maintaining a common ground reference, which simplifies load protection and power sequencing in systems with single-ended grounds.

There is one input to the device

As a DFN-10 surface-mount package, effective copper spread and thermal vias under the package are recommended to dissipate heat and take advantage of the 150°C maximum operating capability.

The 33mΩ on-resistance sets conduction-loss expectations
