S-80142CNPF-JK3TFU

Supervisors Overview

The S-80142CNPF-JK3TFU is a supervisory circuit manufactured by ABLIC Inc., designed for voltage detection with an external delay function. It operates within a supply voltage range of 950 mV to 10 V and features a threshold voltage of 4.2 V. The device provides one monitored input with an active low, open-drain output type. It includes a reset delay time of 27 ms and lacks manual reset or watchdog timer capabilities. The component supports surface mount installation in an SNT-4A-4 package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides voltage monitoring with an external delay function for precise timing control
• Features an active low, open-drain output configuration for flexible interfacing
• Operates with low current consumption suitable for battery-powered applications

Supervisors Applications

• Microcontroller system supervision
• Battery-operated electronic devices
• Portable consumer electronics

Supervisors Procurement Notes

Verify the specific suffix JK3TFU against official ABLIC documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint, specifically the SNT-4A-4 package dimensions. Cross-reference the 4.2 V threshold requirement with system design specifications. Confirm environmental compliance status such as RoHS directives before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.2 V threshold is required for power management. The external delay feature allows customization of reset timing relative to other system events. Consider the open-drain output for level shifting needs. Evaluate the SNT-4A-4 package size constraints against available board space. Verify that the 10 V maximum operating voltage aligns with the highest expected supply rail.

Supervisors Part Context

This part belongs to the S-801 series of supervisory circuits from ABLIC. The series offers various threshold voltages and packages. The S-80142 variant specifically targets applications requiring a 4.2 V detection point. The CNPF suffix indicates specific packaging and marking options. This family is commonly used in portable devices where power efficiency and compact size are critical design factors.

Supervisors Replacement Considerations

Check for parameter-equivalent alternatives like the S-80142CNPF-JK3T2G if availability is constrained. Verify that substitute parts maintain the same 4.2 V threshold and SNT-4A-4 package. Ensure functional compatibility regarding the external delay pin configuration.
