MAX14922ATE+T

Overview

The MAX14922ATE+T is a high-side switch controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 5.5 V and features a non-inverting logic interface. The device provides current limiting capabilities with a maximum output current of 50 mA and an on-resistance of 0.06 ohm. It is housed in a 16-pin TQFN-EP package designed for surface mount installation.

Feature Summary

• Non-inverting high-side switching control
• Integrated current limiting protection
• Low on-resistance for efficient power delivery

Applications

• Industrial load switching
• Automotive peripheral control
• General purpose high-side power distribution

Procurement Notes

Verify the specific suffix 'ATE' against the official datasheet to confirm temperature grade and tape-and-reel specifications. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the manufacturer's latest documentation to confirm active status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a compact, low-current high-side switch solution is required. The 50 mA limit suits low-power loads rather than heavy industrial actuators. Consider the TQFN-EP package for thermal performance and space constraints. Validate that the input logic levels are compatible with the system microcontroller or driver circuitry.

Part Context

This part belongs to the Maxim Integrated high-side switch family, focusing on simple, reliable control of external power paths. It serves as a protective element in circuits where overcurrent conditions must be managed without complex communication protocols. The design prioritizes robustness and ease of integration into standard digital control systems.

Replacement Considerations

Consult the official cross-reference list for direct pin-compatible alternatives. Verify that any substitute maintains the same 50 mA current limit and 0.06 ohm resistance characteristics. Ensure the replacement package matches the 16-TQFN dimensions and thermal pad requirements.
