S-80131BNPF-JGQTFU

Supervisors Overview

The S-80131BNPF-JGQTFU 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 2.2 V to 6.0 V with a fixed detection threshold of 3.1 V and an accuracy of ±2.0%. The device features a typical operating current of 1.3 μA at 3.0 V, ensuring low power consumption. It utilizes an internal oscillator and counter timer to provide a reset delay time of 100 ms without external components. The output is configured as an N-channel open-drain type (Active Low). It is housed in a compact SNT-4A-4 package and supports an operating temperature range from -40 °C to +85 °C.

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to confirm threshold voltage, delay time, and output type. Ensure compatibility with required operating temperatures and package dimensions. Cross-reference manufacturer part numbers to avoid confusion with similar series variants that may differ in electrical characteristics or pin configurations.

Supervisors Selection Notes

Select this component when a fixed 3.1 V threshold is required for systems operating between 2.2 V and 6.0 V. Consider the 100 ms delay time for noise immunity requirements. The N-ch open-drain output is suitable for interfacing with microcontrollers or other logic circuits requiring active-low reset signals. Verify package availability if space constraints are critical.
