FTL7522L6X

Supervisors Overview

The FTL7522L6X is a low current consumption reset timer supervisor integrated circuit manufactured by Fairchild Semiconductor, now part of onsemi. It provides a configurable delay timer specifically designed for resetting mobile devices that require extended reset durations. The device operates within a supply voltage range of 1.8 V to 5 V and functions reliably across an industrial temperature range from -40°C to +85°C. It utilizes a 6-pin MicroPak package and features an open-drain output configuration.

Supervisors Feature Summary

• Configurable delay timer functionality tailored for mobile device reset applications
• Low current consumption design optimized for power-sensitive systems
• Open-drain output interface for flexible logic integration

Supervisors Applications

• Mobile device system resets requiring long delay times
• Embedded systems needing reliable power supervision
• Consumer electronics with strict power management requirements

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels due to obsolete status. Confirm RoHS compliance and package integrity upon receipt. Cross-reference datasheets for pinout and electrical specifications before integration. Check for alternative sources if original stock is unavailable.

Supervisors Selection Notes

Select this component when a fixed-delay reset timer with low quiescent current is required for mobile or embedded applications. Ensure the 1.8V to 5V supply range matches the target system voltage. Consider the open-drain output compatibility with downstream logic levels. Evaluate the 6-MicroPak package constraints against PCB layout requirements.

Supervisors Part Context

This supervisor IC belongs to the family of reset timers designed for portable electronics. It addresses scenarios where standard watchdogs are insufficient due to prolonged boot or recovery sequences. The device simplifies system reliability by automating reset pulses after a defined timeout period triggered by power anomalies.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the part status is listed as obsolete, consult manufacturer archives or authorized distributors for direct replacements or functional equivalents with compatible pinouts and electrical characteristics.
