Overview
The ZXMS81045SPQ-13 is a monolithic N-channel vertical power MOSFET high-side IntelliFET switch from Diodes Incorporated. It integrates temperature and current sensors with a charge-pumped gate supply in an SO-8EP package. The device supports DC 5V to 28V operation with a maximum load current of 4A. Key electrical parameters include a maximum on-resistance of 90mΩ at Tj=150°C and a maximum standby current of 0.5µA. It features integrated protection against short circuits, overvoltage, overheating, and ESD.
Feature Summary
- Integrates protective and diagnostic functions including short circuit, overvoltage, and thermal protection
- Includes onboard current sensing for fault indication such as battery or ground shorts and open loads
- Complies with AEC-Q100 automotive qualification standards and PPAP certification requirements
Applications
- Automotive body control modules
- Vehicle lighting systems including LED and bulb drivers
- Actuator and motor load driving in 12V automotive environments
Procurement Notes
Verify the component meets specific automotive quality requirements by confirming AEC-Q100 compliance and PPAP status. Ensure the selected variant matches the required operating voltage range and thermal management needs for the target application environment.
Selection Notes
Select this component for applications requiring intelligent high-side switching with built-in diagnostics. Consider the SO-8EP package for thermal performance and the integrated charge pump for ease of drive. Evaluate the 4A current rating against peak load requirements.
Part Context
This part belongs to Diodes Incorporated's IntelliFET family of self-protecting high-side switches. These devices are designed to simplify system design by combining power switching with comprehensive protection and feedback mechanisms in a compact footprint suitable for space-constrained automotive electronics.
Replacement Considerations
Check for direct substitutes within the same IntelliFET family that offer similar current ratings and protection features. Verify pin compatibility and thermal characteristics before substituting.
