AP4405AENMH

Overview

The AP4405AENMH is a single-channel voltage detector manufactured by Asahi Kasei Microdevices. It features an adjustable or selectable voltage threshold for precise monitoring. The device utilizes a push-pull/totem pole output configuration and supports both high-active and low-active reset signals. It is housed in a 16-HWQFN (3x3) package with exposed pads, designed for surface-mount installation. The component operates within a temperature range of -40°C to +85°C.

Feature Summary

• Single-channel voltage supervision with adjustable or selectable threshold levels
• Push-pull output driver supporting active-high and active-low reset configurations
• Compact 16-pin HWQFN package with exposed thermal pad for efficient heat dissipation

Applications

• Monitoring power supply rails in portable electronic devices
• System reset generation in embedded microcontroller applications
• Voltage supervision in industrial control modules

Procurement Notes

Verify the specific ordering suffix to confirm the exact threshold voltage selection and reset polarity options required for the design. Confirm that the 16-HWQFN footprint matches the PCB layout, particularly the exposed pad dimensions. Check current availability status as the part may be subject to end-of-life notices or limited stock conditions from distributors.

Selection Notes

Select this component when a single-supervision channel with flexible threshold settings is required. Ensure the operating temperature range meets the environmental specifications of the target application. Consider the push-pull output capability if driving loads directly without additional buffering is necessary. Verify compatibility with the system's logic levels for the reset signal.

Part Context

This part belongs to the AP4405 series of voltage supervisors from Asahi Kasei Microdevices. The series offers various packages and threshold options to suit different board space and performance requirements. It serves as a critical component for ensuring system stability by detecting under-voltage conditions.

Replacement Considerations

Check for direct pin-to-pin replacements within the same AP4405 family with different suffixes for varied thresholds. Evaluate other single-channel supervisors from AKM or competitors with similar HWQFN packaging and adjustable threshold capabilities.
