MCP1316T-29LE/OT

Supervisors Overview

The MCP1316T-29LE/OT is a voltage supervisor IC from Microchip Technology, designed to maintain microcontrollers in reset until system voltage stabilizes. It features an active low push-pull output and a manual reset input. The device monitors a single voltage channel with a threshold of 2.9V. Operating parameters include a supply voltage range of 1V to 5.5V and a maximum supply current of 0.01mA. It supports an operating temperature range from -40°C to +125°C and is housed in a SOT-23-5 package.

Supervisors Feature Summary

• Maintains microcontroller reset state until supply voltage reaches stable operational levels
• Provides active low push-pull output for direct interface with digital logic
• Includes manual reset input capability for external control

Supervisors Applications

• Embedded control systems requiring brown-out protection
• Battery-powered handheld instrumentation
• Telephone handsets and portable devices

Supervisors Procurement Notes

Verify the specific suffix LE/OT against official Microchip documentation to confirm package type and tape/reel specifications. Ensure the 29 threshold designation matches the required trip point for the target application. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 2.9V threshold is required for single-channel monitoring. Consider the active low push-pull output configuration for compatibility with downstream logic. Evaluate the wide operating temperature range for suitability in harsh environments. Compare against other MCP1316 variants if different thresholds or output types are needed.

Supervisors Part Context

This part belongs to the MCP131X/2X family of precision system supervisors. These devices protect microcontrollers, ASICs, and DSPs from supply voltage drops below safe operating levels. The family offers various reset trip points and package options to support diverse embedded control applications.

Supervisors Replacement Considerations

Compatible substitutes within the same family include MCP1316T-27LE/OT (2.7V threshold) and MCP1316T-30CE/OT (3.0V threshold). Verify that the replacement maintains the active low push-pull output and manual reset functionality required by the design.
