MN1381-N

Supervisors Overview

The MN1381-N is a CMOS voltage detection IC designed for simple reset and power-on reset applications. It features a threshold voltage of 3.4V and provides an active high reset signal via a push-pull, totem pole output. The component operates within a supply voltage range of 1.5V to 6V and supports through-hole mounting in a TO-226-3 package. It monitors one voltage channel with a standard reset timeout of 35µs.

Supervisors Feature Summary

• Provides active high reset signal for power management
• Utilizes push-pull totem pole output structure
• Designed for simple reset and power-on reset functions

Supervisors Applications

• Microcontroller system reset circuits
• Power-on reset generation for digital logic
• Voltage monitoring in embedded systems

Supervisors Procurement Notes

Verify the specific suffix 'N' indicates the TO-226-3 through-hole package variant distinct from surface-mount versions like the SQP series. Confirm availability status as Panasonic may have discontinued related metal film resistor lines or updated PMIC portfolios. Ensure the 3.4V threshold aligns with target system voltage requirements before procurement.

Supervisors Selection Notes

Select this component when a through-hole solution is required for voltage supervision. The 3.4V threshold suits 3.3V logic families. Compare against the MN13821 series if surface mount space is constrained. Verify that the push-pull output capability meets the driving requirements of the downstream reset input without additional pull-up components.

Supervisors Part Context

The MN1381-N belongs to the MN1380 series of CMOS LSIs for voltage detection manufactured by Panasonic Electronic Components. This family includes various threshold voltages and package options to support diverse reset requirements in consumer and industrial electronics. The N suffix specifically denotes the through-hole configuration.

Supervisors Replacement Considerations

Public confirmed substitutes are not explicitly listed in the provided documentation. Consider checking Panasonic's current PMIC lineup for equivalent threshold voltages in different packages. Cross-reference with other manufacturers offering 3.4V threshold reset ICs in TO-92/TO-226-3 packages if discontinuation is confirmed.
