MCP1319MT-24QI/OT

Supervisors Overview

The MCP1319MT-24QI/OT is a supervisory circuit from Microchip Technology housed in an SOT-23-5 package. It features an active low open-drain output with an internal 4.7k pull-up resistor and an active high push-pull manual reset input. The device monitors supply voltage with a trip point of 2.4V, providing a reset delay of 1600ms. It operates within a maximum supply voltage of 5.5V and supports an automotive temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides system supervision for microcontrollers and ASICs against brown-out conditions
• Features an active low open-drain output with integrated internal pull-up
• Includes an active high push-pull manual reset input for user-initiated resets

Supervisors Applications

• Embedded control applications requiring voltage monitoring
• Battery-powered operations needing reliable power management
• Automotive electronic systems requiring AEC-Q100 qualification

Supervisors Procurement Notes

Verify the specific suffix '24QI' corresponds to the 2.4V threshold and automotive grade requirements. Confirm the '/OT' designation matches the required reel packaging format. Ensure the SOT-23-5 footprint aligns with the target PCB design. Cross-reference the datasheet revision date to confirm current electrical specifications and pinout definitions before finalizing procurement.

Supervisors Selection Notes

Select this component when an active low open-drain output with an internal pull-up is required alongside a manual reset function. It is suitable for designs needing a 1600ms reset delay and a 2.4V trip point. Consider the SOT-23-5 package size and automotive temperature rating (-40°C to +125°C) as key selection criteria for space-constrained or harsh environment applications.

Supervisors Part Context

This part belongs to the MCP1319 series of system supervisors and reset circuits. The family offers various trip points and output configurations to support microcontrollers, DSPs, and custom chipsets. These devices protect systems from supply voltage drops below safe operating levels, ensuring stable operation in embedded control and instrumentation environments.

Supervisors Replacement Considerations

Check for other MCP1319 variants with different voltage thresholds or output types if the 2.4V trip point does not match the new design requirement. Verify that alternative parts maintain the same SOT-23-5 package and AEC-Q100 qualification if automotive compliance is mandatory.
