MCP130T-485I/TT

Supervisors Overview

The MCP130T-485I/TT is a voltage supervisory circuit manufactured by Microchip Technology, designed to monitor system power integrity. It operates within a supply voltage range of 1 V to 5.5 V and features an active low, open-drain output. The device includes a fixed reset delay time of 350 ms and draws a typical operating current of 60 µA. It is housed in a SOT-23-3 package and is qualified under the AEC-Q100 standard for automotive applications. The component functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Provides reliable voltage supervision with an active low open-drain output interface
• Includes a built-in 350 ms reset delay to ensure stable power-up sequences
• Qualified for automotive environments under the AEC-Q100 reliability standard

Supervisors Applications

• Microcontroller reset circuits in automotive electronic control units
• Power management monitoring in industrial embedded systems
• Voltage supervision for battery-powered portable devices

Supervisors Procurement Notes

Verify the specific suffix 'I/TT' corresponds to the industrial temperature grade and tape-and-reel packaging format. Confirm that the AEC-Q100 qualification aligns with your target application's environmental requirements. Ensure the open-drain output configuration matches your system's pull-up resistor design. Cross-reference the datasheet revision date to confirm compatibility with your design specifications.

Supervisors Selection Notes

Select this component when a simple, low-power voltage supervisor with an active-low output is required. The fixed 350 ms delay suits applications where immediate reset upon voltage drop is not critical. Consider the SOT-23-3 footprint for space-constrained designs. Verify that the 1 V minimum operating voltage covers your lowest expected supply rail during operation.

Supervisors Part Context

This part belongs to the MCP130 series of supervisory circuits from Microchip Technology. The series offers various threshold voltages and output configurations to suit different power monitoring needs. The 'T' indicates tape-and-reel packaging, while 'I' denotes the industrial temperature range. This family is commonly used in consumer, industrial, and automotive electronics for basic power management tasks.

Supervisors Replacement Considerations

Check for other MCP130 variants with compatible threshold voltages if the 4.85 V trigger point does not match the new design requirements. Verify pinout compatibility when substituting with similar open-drain supervisors from other manufacturers.
