Overview
The MAX14919AUP+ is a quad industrial low-side power switch IC designed for load distribution applications. It operates within a voltage range of 4.5V to 5.5V and features an on-resistance of 0.14 ohms per channel. The device is housed in a 20-TSSOP-EP surface-mount package and supports an operating temperature range from -40°C to +125°C. Key protection mechanisms include reverse current detection and under-voltage lockout (UVLO) to safeguard against miswiring faults.
Feature Summary
- Integrates four independent low-side switches with integrated reverse-current detection to prevent damage from load supply miswiring faults.
- Features a low on-resistance of 0.14 ohms per channel for efficient power distribution.
- Includes under-voltage lockout (UVLO) and shutdown functionality for robust system control.
Applications
- PLC/DCS systems
- Relay and solenoid drivers
- Motor control circuits
- Industrial digital outputs
Procurement Notes
Verify the specific suffix 'AUP+' corresponds to the 20-TSSOP-EP package and industrial temperature grade when sourcing. Confirm that the required reverse current protection and UVLO features align with the target application's fault tolerance requirements before finalizing procurement.
Selection Notes
Select this component for applications requiring multiple low-side switching channels with integrated fault protection. Ensure the load voltage stays within the 4.5V to 5.5V range and that the thermal performance of the TSSOP-EP package suits the ambient conditions.
Part Context
This part belongs to the Analog Devices Maxim Integrated family of power load distribution switches. It is specifically categorized as a quad industrial low-side switch, distinct from high-side variants or single-channel devices within the broader portfolio.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official Analog Devices resources for cross-reference data if alternative sourcing is required.
