MCP1316MT-33LE/OT

Supervisors Overview

The MCP1316MT-33LE/OT is a single-channel voltage supervisory circuit manufactured by Microchip Technology. It operates within a supply voltage range of 1 V to 5.5 V and features an active low push-pull output. The device includes a manual reset input and a watchdog timer with a timeout interval of 1600 ms. The reset delay time is specified at 200 ms, and the trip point voltage is set at 3.3 V. It is housed in a SOT-23-5 package and supports surface mount installation across an operating temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer with a fixed timeout interval for automated system recovery from software faults.
• Provides a manual reset input pin allowing external control over the system reset state.
• Delivers an active low push-pull output signal for direct interfacing with digital logic inputs.

Supervisors Applications

• Microcontroller system supervision
• Embedded control applications
• Battery-powered operations

Supervisors Procurement Notes

Verify the specific suffix codes against official Microchip documentation to confirm package type and temperature grade. Ensure the selected variant matches the required threshold voltage and output configuration for the target design. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and compliance status.

Supervisors Selection Notes

Select this component when a fixed 3.3 V monitoring threshold is required for systems powered between 1 V and 5.5 V. The integrated watchdog and manual reset features make it suitable for designs needing robust fault protection without additional discrete components. Consider the SOT-23-5 package size for space-constrained PCB layouts.

Supervisors Part Context

This device belongs to the MCP131x family of system supervisors and reset circuits from Microchip Technology. The family provides precision monitoring solutions for microcontrollers, ASICs, and DSPs. These circuits protect systems from brown-out conditions caused by supply voltage drops below safe operating levels.

Supervisors Replacement Considerations

Consult official Microchip documentation for verified substitute part numbers within the MCP131x series that match the required voltage threshold and package specifications.
