MIC803-40D2VC3-TR

Supervisors Overview

The MIC803-40D2VC3-TR is a voltage supervisory circuit manufactured by Microchip Technology, designed for monitoring single-input power rails. It operates within a supply voltage range of 1 V to 5.5 V and features a precise threshold voltage of 4 V with an accuracy of 2.5%. The device provides an open-drain reset output with a fixed reset delay time of 35 ms. It does not include manual reset, watchdog timer, or battery backup switching functions. The component is housed in a compact SC-70-3 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides open-drain reset output for microprocessor supervision
• Operates over a wide supply voltage range from 1 V to 5.5 V
• Ensures high threshold accuracy for reliable voltage monitoring

Supervisors Applications

• Microprocessor supervisor circuits
• Voltage monitoring in portable electronics

Supervisors Procurement Notes

Verify the specific suffix VC3 corresponds to the SC-70-3 package when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the open-drain output configuration matches the target system's pull-up requirements. Cross-reference the exact part number against current datasheets to validate pinout and electrical characteristics.

Supervisors Selection Notes

Select this component when a low-power, single-channel supervisor is required for voltages near 4 V. The SC-70-3 package offers space efficiency for dense layouts. Consider the 35 ms reset delay and lack of manual reset functionality during design. Verify that the 2.5% threshold accuracy meets the application's tolerance requirements.
