AAT4687IJQ-T1

Overview

The AAT4687IJQ-T1 is a power switch IC designed for power distribution and over-voltage protection. It features a single output capable of delivering up to 1.8 A of current with a maximum on-resistance of 130 mOhms. The device operates within a supply voltage range of 3 V to 14 V and dissipates up to 625 mW of power. It supports a maximum run time of 10 ms and an idle time of 9 ms. The component functions reliably across a temperature range of -40°C to +85°C and is housed in a 10-SC70JW surface-mount package.

Feature Summary

• Provides integrated over-voltage protection for power distribution applications
• Supports high current delivery with low on-resistance characteristics
• Configurable timing controls for run and idle states

Applications

• Battery protection circuits for lithium-ion systems
• Power distribution networks requiring over-voltage safeguards
• Electronic devices needing controlled power switching

Procurement Notes

This component has reached the end-of-life stage, as confirmed by manufacturer discontinuance notifications. Availability is restricted, and distributors may not stock this part in all regions. Engineers must verify current supply status through authorized channels before design finalization. Sourcing should focus on remaining inventory or approved alternative sources, considering the product's obsolete status and potential lead time constraints.

Selection Notes

Select this IC when designing circuits that require robust over-voltage protection combined with power switching capabilities. The 1.8 A output rating and 130 mOhm resistance suit moderate load applications. Ensure the input voltage stays within the 3 V to 14 V range. The SC70JW package offers space efficiency for compact designs. Verify thermal management requirements given the 625 mW power dissipation limit and operating temperature specifications.
