TC1271ATCVCTTR

Supervisors Overview

The TC1271ATCVCTTR is a single-channel voltage supervisory circuit manufactured by Microchip Technology, designed for power-on reset and monitoring applications. It operates within a supply voltage range of 1V to 5.5V and features a fixed reset threshold of 3.08V. The device provides an active low push-pull output with a manual reset input capability. It includes a typical reset delay time of 17.5ms to ensure stable power sequencing. The component is qualified under AEC-Q100 standards for automotive reliability and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable power supervision with a fixed 3.08V reset threshold for precise voltage monitoring
• Features an active low push-pull output driver compatible with various digital logic families
• Includes a manual reset input pin allowing external control over the reset state
• Qualified for automotive applications meeting AEC-Q100 stress test requirements

Supervisors Applications

• Microcontroller power-on reset generation in embedded systems
• Voltage monitoring for battery-powered portable devices
• Automotive electronic control unit (ECU) power supervision
• Industrial equipment power management and fault detection

Supervisors Procurement Notes

Verify the exact suffix 'TC' corresponds to the active low output configuration before procurement. Confirm that the SOT-23-5 package variant matches your PCB footprint requirements. Ensure the AEC-Q100 qualification status meets your specific automotive or industrial reliability standards. Cross-reference the 3.08V threshold against your system's minimum operating voltage to prevent false resets during normal operation.

Supervisors Selection Notes

Select this component when a fixed low-voltage threshold near 3.08V is required for microcontroller supervision. The active low output makes it suitable for systems where a low signal indicates a valid power state. Consider the 17.5ms reset delay for timing-sensitive applications requiring quick recovery after power stabilization. The wide operating temperature range supports deployment in harsh environmental conditions without derating concerns.

Supervisors Part Context

This part belongs to the TC1271A series of voltage supervisors from Microchip Technology. The series offers various threshold voltages and output polarities to suit different system architectures. The TC1271ATCVCTTR specifically denotes the active low output version in a tape-and-reel SOT-23-5 package. It complements other variants like the TC1271AMVCTTR which features an active high output.

Supervisors Replacement Considerations

Public confirmed substitute: TC1270ATCVCTTR. Note that while functionally similar, verify threshold voltage compatibility as the TC1270ATCVCTTR also utilizes a 3.08V threshold but may have different electrical characteristics.
