S-80146BLPF-JE7TFU

Supervisors Overview

The S-80146BLPF-JE7TFU is a supervisory circuit manufactured by ABLIC, designed for voltage monitoring applications. It operates within a supply voltage range of 0.95 V to 10.0 V and features a fixed detection threshold voltage of 4.632 V with an accuracy of ±2.0%. The device incorporates a built-in delay timer set to 100 ms typ., eliminating the need for external timing components. It consumes a typical operating current of 1.3 μA at 2.5 V. The output is configured as an N-channel open-drain type providing an active-low signal. The component is housed in a compact SNT-4A-4 package suitable for surface mount technology.

Supervisors Feature Summary

• Integrates a built-in delay timer to prevent false resets without requiring external components
• Provides high-accuracy voltage detection with a fixed internal threshold
• Features ultra-low power consumption suitable for battery-operated systems

Supervisors Applications

• Power monitoring for portable equipment such as notebook computers
• Voltage supervision for digital still cameras
• System reset control for PDA devices

Supervisors Procurement Notes

Verify the specific suffix JE7TFU to confirm the 100 ms delay time and 4.632 V threshold voltage, as these parameters vary across the S-801 series. Ensure compatibility with the SNT-4A-4 footprint during PCB layout. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Supervisors Selection Notes

Select this part when a fixed 4.632 V threshold and 100 ms release delay are required. Compare against other series suffixes if different delay times (50 ms or 200 ms) or threshold voltages are needed. Consider the S-801 series family for alternative pinouts or output types if the open-drain configuration does not meet system requirements.

Supervisors Part Context

This component belongs to the S-801 series of supervisory circuits from ABLIC. The series is characterized by CMOS construction, low operating current, and various delay options. The S-80146 variant specifically denotes the 4.632 V detection threshold, while the BLPF suffix indicates the package type and delay characteristics within the product line.

Supervisors Replacement Considerations

Check for direct substitutes within the S-801 series that share the same threshold voltage but offer different delay times, such as those with suffixes corresponding to 50 ms or 200 ms delays. Verify package compatibility with the SNT-4A-4 form factor before considering cross-series replacements.
