AP4405AENJG

Overview

The AP4405AENJG is a single-channel voltage supervisor integrated circuit manufactured by Asahi Kasei Microdevices. It features an adjustable or selectable threshold voltage for precise monitoring applications. The device utilizes a push-pull or totem pole output configuration and supports both high-active and low-active reset signals. It operates within a temperature range of -40°C to 85°C (TA). The component is housed in a 16-HWQFN package with dimensions of 3x3 mm, designed for surface-mount installation.

Feature Summary

• Adjustable or selectable threshold voltage capability
• Push-pull or totem pole output structure
• Configurable active-high or active-low reset signal

Applications

• Power management systems requiring voltage supervision
• Electronic circuits needing precise threshold monitoring
• Industrial equipment operating in extended temperature ranges

Procurement Notes

Verify the specific ordering suffix to confirm the exact package variant and tape-and-reel quantity specifications. Ensure compatibility with the target PCB footprint for the 16-HWQFN form factor. Confirm that the adjustable threshold requirements align with the selected external resistor network or internal settings. Check for any recent production change notices regarding material composition or packaging updates.

Selection Notes

Select this component when a single-channel supervisor with flexible threshold settings is required. Consider the 16-HWQFN package size constraints for dense layouts. Evaluate the need for configurable reset polarity against system logic levels. Verify that the operational temperature range meets the environmental demands of the end application.

Part Context

This part belongs to the AP4405 series of power supervisors from Asahi Kasei Microdevices. It shares core functionalities with variants like the AP4405AENMH but differs in package type. The series focuses on reliable voltage monitoring for critical system components.

Replacement Considerations

The AP4405AENMH is a documented substitute part number offering similar functional characteristics. Verify pinout compatibility and package dimensions before substitution.
