MAX869LEEE+T

Overview

The MAX869LEEE+T is a high-side power distribution switch manufactured by Analog Devices Inc. (Maxim Integrated). It features a single P-channel output capable of handling up to 2A of load current with a typical on-resistance of 38 milliohms. The device operates within a load voltage range of 2.7V to 5.5V and includes adjustable current limiting and overtemperature protection. It utilizes an open-drain status flag for fault indication and is housed in a 16-QSOP surface-mount package, operating across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates adjustable current limiting and thermal shutdown for robust fault protection
• Provides an open-drain status flag to indicate operational state or fault conditions
• Features low on-resistance for efficient power delivery in high-side switching applications

Applications

• Power distribution in portable electronic devices
• Load switching in automotive infotainment systems
• Peripheral power management in industrial control units

Procurement Notes

Verify the specific suffix '+T' against the manufacturer's official documentation to confirm reel packaging specifications. Ensure the component matches the exact 16-QSOP footprint and pinout requirements for your design. Cross-reference the datasheet revision date to confirm compatibility with your system's electrical constraints and environmental standards.

Selection Notes

Select this component when a high-side switch with integrated protection is required for loads up to 2A. Consider the 38 milliohm on-resistance for efficiency calculations and verify that the 2.7V to 5.5V input range aligns with your system's supply voltage. The adjustable current limit allows customization for different load profiles without external sensing resistors.

Part Context

The MAX869LEEE+T belongs to Maxim Integrated's family of high-side power switches designed for reliable load management. These devices are commonly used to protect sensitive circuits from overcurrent and thermal events. The part integrates control logic and power MOSFETs into a compact package, simplifying board layout compared to discrete solutions.

Replacement Considerations

Consult the official product discontinuance notice for authorized replacement part numbers. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
