S-80146ALMC-JA7T2G

Supervisors Overview

The S-80146ALMC-JA7T2G is a single-channel voltage detector manufactured by ABLIC Inc. It operates within a supply voltage range of 1.4V to 5.5V and features a fixed detection threshold of 4.6V. The device provides an active-low reset output with a minimum delay time of 32.5ms. It supports both push-pull/totem pole and open-drain/open-collector output configurations, selectable via external pins. Operating temperatures range from -40°C to +85°C in a compact SOT-23-5 package.

Supervisors Feature Summary

• Configurable output structure supporting both push-pull and open-drain modes
• Integrated reset delay timer for stable power-on sequencing
• Low current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor system supervision
• Battery voltage monitoring
• Portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix JA7T2G against official datasheets to confirm the exact output configuration and tolerance. Ensure compatibility with the target PCB footprint and thermal requirements. Confirm RoHS compliance status for the specific manufacturing batch before integration into final assemblies.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for system supervision. The choice between push-pull and open-drain outputs should align with the downstream logic interface requirements. Verify that the 32.5ms minimum delay meets the system's startup timing constraints.

Supervisors Part Context

This part belongs to the S-801 series of voltage detectors designed for portable equipment. It complements other ABLIC PMICs by providing essential power management supervision functions in a minimal footprint.
