Overview
The Infineon 98-0478PBF is a USB power switch and load switch featuring an N-channel output configuration housed in an SOIC-8 surface-mount package. It supports a maximum load voltage of 28V and delivers an output current of 500mA with a typical on-resistance of 160mΩ. The device operates within a temperature range of -40°C to +150°C and utilizes a non-inverting interface for control. Integrated fault protection mechanisms include fixed current limiting and overtemperature shutdown, ensuring reliable operation in low-side switching applications.
Feature Summary
- Integrates fixed current limiting and overtemperature protection for enhanced circuit safety
- Features a non-inverting input interface compatible with standard logic levels
- Provides low-side switching capability optimized for USB power distribution
Applications
- USB port power management and protection
- Load switching for peripheral devices
- Overcurrent protection circuits
Procurement Notes
Verify the specific suffix PBF confirms lead-free compliance and RoHS standards before procurement. Confirm that the SOIC-8 package dimensions match the target PCB footprint requirements. Ensure the operating voltage and current ratings align with the specific application load to prevent exceeding the 500mA limit or 28V maximum rating during design validation.
Selection Notes
Select this component when designing low-voltage USB power paths requiring integrated fault protection. The 160mΩ on-resistance offers a balance between conduction loss and cost for moderate current loads. Consider the thermal performance in the SOIC-8 package if continuous high-current operation is expected near the 500mA limit.
Part Context
This part belongs to the category of power switches and load switches manufactured by Infineon Technologies. It serves as a protective element in electronic systems, specifically designed to manage power delivery to downstream components while monitoring for electrical faults such as short circuits or excessive heat generation.
FAQ
What type of fault protection does the 98-0478PBF provide?
The device includes fixed current limiting and overtemperature shutdown features to protect both the switch and the connected load from damage.
Is the input signal inverting or non-inverting?
The 98-0478PBF utilizes a non-inverting input interface, meaning a high logic level turns the switch on.
