MIC6315-30D4UY-TR

Supervisors Overview

The MIC6315-30D4UY-TR is a voltage supervisory circuit manufactured by Microchip Technology, designed to monitor power supplies in microprocessor-based systems. It features an active low, open-drain reset output and includes a manual reset input for system control. The device asserts a reset signal when the monitored supply voltage drops below a designated threshold of 3.00V or when the manual reset pin is forced low. It guarantees a minimum reset pulse width of 1.5 seconds after the supply voltage rises above the threshold. The component operates within a supply voltage range up to 5.5V and supports surface-mount installation in a compact SOT-143-4 package.

Supervisors Feature Summary

• Monitors single-channel power supply voltage with a fixed 3.00V threshold
• Provides active low, open-drain reset output for system integration
• Includes manual reset input capability for external control
• Ensures a minimum 1.5-second reset delay after voltage recovery

Supervisors Applications

• Microprocessor-based system power supply monitoring
• Embedded controller reset generation
• Voltage supervision for 3V logic circuits

Supervisors Procurement Notes

Verify that the specific suffix D4UY corresponds to the required 1.5-second reset delay characteristic, as other variants in the MIC6315 family offer different timing options such as 20ms or 140ms. Confirm that the 3.00V threshold aligns with the target application's voltage requirements. Ensure the SOT-143-4 package footprint matches the PCB design constraints. Cross-reference the manufacturer part number with official Microchip documentation to confirm current production status and environmental compliance details before finalizing procurement.

Supervisors Selection Notes

Select this component when a precise 3.00V threshold is required for voltage supervision in 3V-powered systems. The 1.5-second reset delay makes it suitable for applications requiring extended stabilization time after power restoration. Consider the open-drain output configuration for compatibility with various logic levels. Evaluate the manual reset feature if external system control over the reset state is necessary. Compare against other MIC6315 variants to ensure the specific timing and voltage parameters match the design specifications without unnecessary complexity.

Supervisors Part Context

The MIC6315 series comprises inexpensive reset generator circuits designed for monitoring power supplies in microprocessor systems. This specific variant belongs to the broader MIC6315 family, which offers multiple threshold voltages and reset delay options to accommodate different system requirements. Manufactured by Microchip Technology, these devices are part of the PMIC - Power Management ICs category. The series is known for providing reliable voltage supervision in a compact surface-mount package, supporting both simple reset and power-on reset functions for embedded applications.
