Overview
The MAX14919AAUP+T is a quad industrial low-side switch manufactured by Analog Devices Inc./Maxim Integrated. It features four N-channel outputs with a maximum current of 800mA per channel and a typical on-resistance of 140 milliohms. The device operates within a load voltage range of 4.5V to 5.5V and includes an integrated 5V regulator. Protection features include over-temperature, reverse current, short-circuit, and UVLO. It utilizes a non-inverted parallel interface and is housed in a 20-WFQFN (4x5) package with exposed pad.
Feature Summary
- Integrates four independent low-side switches for industrial power distribution
- Includes built-in 5V linear regulator for internal circuitry support
- Provides comprehensive fault protection against thermal, reverse current, and short-circuit conditions
Applications
- Industrial power distribution systems
- Relay and solenoid driver circuits
- General-purpose load switching in automation equipment
Procurement Notes
Verify the specific suffix 'AAUP' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 20-WFQFN package dimensions align with your PCB footprint. Confirm that the operating temperature range of -40°C to +125°C meets your environmental specifications before finalizing procurement.
Selection Notes
Select this component when a compact quad low-side switch solution is required for industrial applications. The integrated 5V regulator simplifies power management by eliminating the need for an external supply for the control logic. Consider the 140mΩ on-resistance for efficiency calculations and ensure the 800mA per-channel limit suits the connected loads. The exposed pad design aids in thermal dissipation for surface-mount assembly.
Part Context
This part belongs to the MAX14919 family of industrial low-side switches from Maxim Integrated, now part of Analog Devices. The family offers various channel counts and packaging options tailored for robust power management in harsh environments. The AAUP variant specifically denotes the 20-WFQFN package configuration, distinguishing it from other form factors like TQFN or LFCSP available within the same functional series.
Replacement Considerations
Cross-reference with MAX14919AATP+T for alternative packaging (TQFN) if board layout changes are permissible. Verify compatibility with MAX14919AUP+T for standard WFQFN variants. No direct single-pin replacements exist; redesign may be required for different channel counts or high-side configurations.
