MAX1922ESA+T

Overview

The MAX1922ESA+T is a single-channel, high-side power switch IC designed for USB port distribution. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of up to 1 A. The device features a typical on-resistance of 70 mΩ and includes integrated fault protection mechanisms such as fixed current limiting at 1.75 A, over-temperature shutdown, and under-voltage lockout (UVLO). It utilizes a non-inverting control interface and is housed in an 8-SOIC surface-mount package.

Feature Summary

Integrates fixed current limiting and thermal shutdown for robust fault protection
Features low on-resistance for efficient power distribution
Supports non-inverting logic control for simple interface integration

Applications

USB port power switching and distribution
Portable electronic device power management
Battery-powered system load switching

Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status with the manufacturer. Ensure the SOIC-8 footprint matches your PCB design. Check for regional availability restrictions as some distributors may limit sales. Validate that the 1A continuous current rating meets your specific load requirements.

Selection Notes

Select this component for applications requiring a single-channel high-side switch with built-in protection. It is suitable for USB peripherals where current limiting prevents bus damage. Consider the 70 mΩ on-resistance for efficiency needs. The wide operating temperature range supports industrial environments. Verify compatibility with the host controller's logic levels.

Part Context

This part belongs to the MAX1922 series of USB power switches from Maxim Integrated. It is specifically engineered for portable devices needing reliable power distribution. The series offers various packages including tube and reel options. It complements other Maxim PMIC solutions for complete power management systems.
