MAX6315US26D2

Supervisors Overview

The MAX6315US26D2 is a voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold voltage of 2.6 V. The device provides an active-low, open-drain reset output with a manual reset input capability. It consumes only 5 µA of supply current and offers high accuracy of 1.8%. The component supports a minimum reset timeout delay of 140 ms and functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors power-supply voltages and asserts reset when voltage falls below the factory-set threshold
• Provides manual reset functionality via dedicated input pin
• Features low-power consumption suitable for battery-operated applications
• Delivers active-low open-drain reset output compatible with various logic families

Supervisors Applications

• Microprocessor (µP) reset circuits in embedded systems
• Portable instrumentation requiring low standby current
• Battery-powered consumer electronics
• Industrial control systems operating in harsh environments

Supervisors Procurement Notes

Verify the exact suffix D2 against official datasheets to confirm the specific reset timeout value, as variations exist within the MAX6315 family. Confirm RoHS compliance status and lead-free packaging details with the manufacturer or authorized distributors before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 2.6 V threshold is required for system supervision. Consider the 1.8% accuracy and 5 µA quiescent current for precision and efficiency needs. Ensure the SOT-143-4 package fits the PCB layout constraints and that the active-low open-drain output aligns with the target microcontroller's reset input requirements.

Supervisors Part Context

The MAX6315 series belongs to Maxim Integrated's line of low-voltage, low-power microprocessor reset circuits. These devices are designed to monitor single power supplies and provide reliable reset signals to ensure proper system startup and operation under varying voltage conditions.

Supervisors Replacement Considerations

Check for direct cross-references such as MIC6315 variants from Microchip Technology. Verify pinout compatibility and electrical parameter alignment, particularly threshold voltage and reset timeout, before substituting.
