S-80134BLPF-JETTFG

Supervisors Overview

The S-80134BLPF-JETTFG is a voltage detector manufactured by ABLIC Inc., designed for power supply monitoring in portable electronic equipment. It operates within a supply voltage range of 0.95 V to 10.0 V and features a fixed detection threshold of 3.4 V with an accuracy of ±2.0%. The device incorporates a built-in delay timer, specifically the B-type configuration which provides a typical release delay of 100 ms without requiring external components. It utilizes a CMOS process technology and offers an N-channel open-drain output that activates low when the monitored voltage falls below the threshold. The component is housed in a compact SNT-4A package, suitable for surface-mount applications, and supports an operating temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Integrates a fixed internal detection threshold with high accuracy for reliable power supervision.
• Includes a built-in counter timer to delay signal release, eliminating the need for external timing components.
• Features an N-channel open-drain output structure compatible with various logic families.
• Designed for ultra-low power consumption to extend battery life in portable devices.

Supervisors Applications

• Power monitoring for notebook computers
• Voltage supervision in digital still cameras
• System reset control for personal digital assistants (PDAs)
• Battery backup switching circuits

Supervisors Procurement Notes

Verify the specific suffix JETTFG against the manufacturer's current obsolescence announcements, as ABLIC frequently updates packaging and plating specifications. Confirm availability through authorized distributors, noting that some variants may be subject to limited supply or end-of-life status. Ensure the ordering part number matches the required delay time and output type specified in the design requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 3.4 V threshold and a 100 ms delay are required for system reset functions. The SNT-4A package is appropriate for space-constrained designs. Compare the N-channel open-drain output capability with system input requirements to ensure proper interfacing. Consider the operating temperature range and supply voltage limits to ensure compatibility with the target application environment.

Supervisors Part Context

This device belongs to the S-801 series of voltage detectors from ABLIC, which are characterized by low current consumption and small package sizes. The series is widely used in portable electronics where power efficiency and board space are critical constraints. The S-801 series typically offers various threshold voltages and delay options to accommodate different system requirements.

Supervisors Replacement Considerations

Direct replacements must match the 3.4 V threshold, 100 ms delay, and SNT-4A package. Verify pinout compatibility and output drive capabilities. Check for any changes in electrical characteristics such as quiescent current or accuracy if substituting with other manufacturers' parts.
