MAX894LESA+

Overview

The MAX894LESA+ is a dual, current-limited, high-side power distribution switch manufactured by Analog Devices Inc. (Maxim Integrated). It features two independent P-channel switches in an 8-pin SOIC package. The device provides integrated overcurrent protection with automatic retry functionality upon fault clearance. It supports load voltages up to 5.5V and delivers continuous output currents of 500mA per channel. The component operates within a temperature range of -40°C to +85°C and includes thermal shutdown protection for enhanced reliability.

Feature Summary

• Dual independent high-side P-channel power switches
• Integrated current limiting with automatic retry
• Thermal shutdown protection
• Low on-resistance for efficient power distribution

Applications

• Portable consumer electronics power management
• Industrial control system load switching
• Battery-powered device power distribution
• Peripheral interface power control

Procurement Notes

Verify the specific suffix (+) indicates lead-free compliance when sourcing. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the supply chain source provides valid manufacturer traceability documentation. Check for any obsolescence notices or lifecycle status updates from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when dual-channel high-side switching with built-in current protection is required. Consider the 500mA per channel limit against peak load demands. Evaluate the automatic retry feature suitability for your application's fault tolerance needs. Compare alternative single-channel devices if only one switch is necessary to optimize board space.

Part Context

This part belongs to the Maxim Integrated power switch family, designed for compact power distribution solutions. It complements other Maxim PMICs by providing robust load protection in small form factors. The series is commonly used in applications requiring reliable, protected power routing for multiple loads from a single source.

FAQ

What happens during an overcurrent event?

The device limits the output current and eventually shuts off the switch. Upon fault clearance, it automatically retries.

Is manual reset available?

No, the MAX894LESA+ uses automatic retry after the fault condition is removed.
