S-8424AAHFT-TB-G

Power Supply Controllers, Monitors Overview

The S-8424AAHFT-TB-G is a CMOS integrated circuit designed for battery backup switching applications. It integrates two voltage regulators, three voltage detectors, and a power supply switch with controller on a single chip. The device operates within a temperature range of -40°C to +85°C and is housed in an 8-pin TSSOP package. Normal operation current consumption is specified at a maximum of 15 µA when the input voltage is 6 V.

Power Supply Controllers, Monitors Feature Summary

• Integrates dual voltage regulators, triple voltage detectors, and a power supply switch controller for unified backup system management
• Provides three distinct voltage detection output signals corresponding to the main power supply voltage levels
• Utilizes specialized sequence control logic to optimize the utilization efficiency of backup power resources

Power Supply Controllers, Monitors Applications

• Primary and backup power supply switching circuits
• Microcontroller system power management configurations
• Battery backup system architecture design

Power Supply Controllers, Monitors Procurement Notes

Verify that the suffix 'G' confirms RoHS compliance status as indicated by manufacturer documentation. Confirm the specific voltage detector thresholds and regulator outputs match the application requirements, as these are fixed parameters defined by the part number variant. Ensure the TSSOP-8 package dimensions align with the PCB footprint specifications before finalizing procurement orders.

Power Supply Controllers, Monitors Selection Notes

Select this component when designing systems requiring integrated primary-to-backup power switching with simultaneous voltage monitoring. The fixed threshold detectors eliminate the need for external comparator components. Consider the low quiescent current specification for battery-sensitive designs where standby power drain must be minimized across the operational temperature range.

Power Supply Controllers, Monitors Part Context

This part belongs to the S-8424A Series from ABLIC Inc., which specializes in CMOS ICs for power supply support functions. The series focuses on consolidating multiple power management tasks into a single compact package, reducing board space and component count for portable and embedded electronic devices requiring reliable backup power strategies.

Power Supply Controllers, Monitors Replacement Considerations

Check for other variants within the S-8424A family that may offer different voltage detector thresholds or regulator outputs while maintaining the same TSSOP-8 package and functional architecture.
