MAX6312UK43D3

Supervisors Overview

The MAX6312UK43D3+T is a CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a fixed reset threshold of 4.3 V with an accuracy of 2.5%. The device monitors one input, provides an active low open drain output, and includes manual reset capability alongside a watchdog timer. It exhibits a reset delay time of 225 ms and consumes only 7 uA of operating supply current. The component is housed in a SOT-23-5 package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates manual reset functionality with a built-in watchdog timer for comprehensive system protection.
• Features ultra-low power consumption suitable for battery-operated portable applications.
• Provides precise factory-set voltage supervision with immunity to short transients on monitored supplies.

Supervisors Applications

• Monitoring power supplies in personal computer systems
• Supervisory circuits for portable electronic devices
• Embedded system power management

Supervisors Procurement Notes

Verify the specific suffix (e.g., +T) for packaging configuration such as cut tape or reel. Confirm RoHS compliance status through official documentation. Check lifecycle status as availability may be limited or discontinued. Ensure the manufacturer part number matches exactly before ordering.

Supervisors Selection Notes

Select this component when a single-channel supervisor with both manual reset and watchdog timer is required. Compare against similar models like MAX6854 which lacks a watchdog timer. Verify that the 4.3 V threshold aligns with the target system voltage requirements. Consider the SOT-23-5 package size constraints for PCB layout.

Supervisors Part Context

This part belongs to the MAX63xx series of 5-pin multiple-input programmable reset ICs designed by Maxim Integrated. These circuits are engineered to monitor power supplies and assert a system reset if voltages fall outside programmed thresholds. The series is characterized by low supply current and small package dimensions, making it ideal for space-constrained portable applications.

Supervisors Replacement Considerations

MAX6854UK43D3+T: Similar threshold but lacks watchdog timer and has push-pull output.
