MAX6315US26D2+T

Supervisors Overview

The MAX6315US26D2+T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single power supply input with a fixed threshold voltage of 2.63V and an overvoltage threshold of 2.68V. The device features an active-low, open-drain reset output and supports manual reset functionality. It operates within a supply voltage range up to 5.5V and maintains a typical quiescent current of 5µA. The reset timeout period is specified at 140ms minimum. The component is housed in a compact SOT-143-4 surface-mount package and is rated for operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset assertion when monitored supply voltage falls below the preset threshold
• Features an active-low open-drain output compatible with standard digital logic interfaces
• Includes a debounced manual reset input for user-initiated system control
• Designed for ultra-low power consumption suitable for battery-operated portable applications

Supervisors Applications

• Monitoring power supplies in microprocessor and digital systems
• Portable electronic devices requiring low standby current
• Battery-powered equipment needing voltage supervision
• Industrial control systems operating in extended temperature environments

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and lead-free specifications prior to integration. Check for obsolete status or end-of-life notifications as manufacturing transitions may affect long-term supply stability. Ensure packaging details match design requirements for surface-mount assembly processes.

Supervisors Selection Notes

Select this component when a fixed 2.63V threshold is required for single-supervision applications. Consider the SOT-143-4 package size for space-constrained designs. Evaluate the 5µA quiescent current against system power budgets. Verify that the open-drain output configuration aligns with the target microprocessor's reset input requirements. Compare alternative thresholds if the 2.63V level does not match the specific rail being monitored.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits, designed for monitoring power supplies in microprocessor systems. The series offers various threshold voltages and package options to suit different application needs. The MAX6315 family emphasizes low power consumption and small form factors, making it suitable for portable and industrial electronics where reliability and efficiency are critical.

Supervisors Replacement Considerations
