MCP1319T-29LE/OT

Supervisors Overview

The MCP1319T-29LE/OT is a single-channel voltage supervisory circuit manufactured by Microchip Technology. It operates within a supply voltage range of 1V to 5.5V and features a fixed threshold voltage of 2.9V with an overvoltage threshold of 2.944V. The device provides active high, active low, open drain, and push-pull outputs with a reset delay time of 200ms. It consumes only 10µA of operating current and functions reliably across a temperature range of -40°C to +125°C. Packaged in SOT-23-5, it supports manual reset inputs without watchdog or battery backup switching capabilities.

Supervisors Feature Summary

• Provides multiple output configurations including active high, active low, open drain, and push-pull modes for flexible system integration
• Maintains microcontroller reset until supply voltage stabilizes above the safe operating level to prevent brown-out conditions
• Supports manual reset functionality allowing external control over the reset state independent of voltage monitoring

Supervisors Applications

• Embedded control applications requiring reliable power supervision
• Battery-powered operations needing low quiescent current consumption
• Hand-held instrumentation systems demanding compact surface-mount packaging

Supervisors Procurement Notes

Verify the specific suffix codes against official Microchip documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering information matches the required output type and package variant. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and current production status before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a single-channel supervisor with versatile output options is required. The fixed 2.9V threshold suits systems operating near this voltage level. Consider the 10µA current draw for battery-sensitive designs. Verify that the SOT-23-5 package fits the board layout constraints and that the absence of watchdog timer meets the application safety requirements.

Supervisors Part Context

This device belongs to the MCP131X family of precision system supervisors designed for microcontrollers and ASICs. The family offers various trip points and packages to address diverse embedded control needs. These circuits protect against supply voltage drops below safe operating levels, ensuring system reliability in portable and industrial environments where power stability is critical.

Supervisors Replacement Considerations

MIC2788-XYMT-TR is listed as a discontinued alternative; however, it is a dual-channel device in an 8-TMLF package, requiring significant design changes. No direct single-channel pin-compatible substitutes are confirmed in the provided data.
