Overview
The MAX14919AAUP+ is a quad-channel industrial low-side power switch manufactured by Analog Devices Inc. It features an integrated 1kV/42Ω surge protection circuit to ensure robust operation in harsh environments. The device provides four independent high-current outputs with a typical on-resistance (RON) of 140mΩ per channel. It supports a supply voltage range of 4.5V to 36V and operates within a temperature range of -40°C to +125°C. The component utilizes a TSSOP-EP-20 surface-mount package.
Feature Summary
- Integrates 1kV/42Ω transient voltage surge suppression for enhanced system resilience
- Provides precise current limiting capability adjustable via external resistors
- Features low on-resistance for efficient power distribution and minimal heat generation
Applications
- Industrial load distribution systems
- Automotive electronic control units
- High-reliability power switching networks
Procurement Notes
Verify the specific AAUP+ suffix against official datasheets to confirm pinout and thermal pad configuration. Ensure the supplier provides valid traceability documentation. Confirm that the component meets RoHS compliance standards required for your assembly process. Cross-reference the ordering part number with the manufacturer's latest release notes to avoid obsolete variants.
Selection Notes
Select this component when four isolated low-side switches are required with integrated surge protection. It is suitable for applications demanding high reliability under electrical stress. Consider the 140mΩ on-resistance for power loss calculations. Verify that the external resistor network aligns with the desired current limit thresholds specified in the technical data.
Part Context
This part belongs to the MAX14919 family of industrial power switches. It complements other devices like the MAX14917 and MAX14916, which offer different channel counts or high-side configurations. The series is designed for demanding industrial and automotive environments requiring robust fault protection and precise load management capabilities.
Replacement Considerations
Direct substitutes include the MAX14919AUP+ and MAX14919AATP+. Verify package compatibility and thermal performance when swapping between tape-and-reel and tube packaging options.
