MAX6315US26D2-T

Supervisors Overview

The MAX6315US26D2-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It features an active-low open-drain reset output that asserts when the supply voltage falls below a preset threshold of 2.63V. The device includes a manual reset input for debounced user-initiated resets. It operates within a supply voltage range of 1V to 5.5V, with a typical quiescent current of 5µA. The reset timeout period is typically 280ms. The component is housed in a compact SOT-143-4 surface-mount package and supports an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset by monitoring supply voltage against a fixed threshold
• Includes a debounced manual reset input for direct user interface control
• Features an active-low open-drain output compatible with various logic families
• Designed for ultra-low power consumption suitable for battery-operated applications

Supervisors Applications

• Microprocessor (µP) power supply supervision
• Digital system voltage monitoring
• Battery-powered portable devices requiring low standby current
• Embedded systems needing manual reset capability

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status as some variants may differ. Check lead time and availability as this series may be subject to obsolescence or discontinuation notices from Analog Devices/Maxim Integrated. Ensure the operating temperature grade matches application requirements.

Supervisors Selection Notes

Select this part when a fixed 2.63V threshold is required for system supervision. Consider the open-drain output if external pull-up voltage levels differ from the monitored supply. Evaluate the 280ms reset delay against system startup timing requirements. Compare against other MAX6315 variants if different thresholds or faster reset times are needed.

Supervisors Part Context

The MAX6315 series consists of low-power µP reset circuits offering various factory-set thresholds. This specific model provides a 2.63V trip point. It belongs to a family of supervisory ICs designed to eliminate external components and adjustments, enhancing reliability while reducing cost in embedded designs.

Supervisors Replacement Considerations

Direct substitutes include other MAX6315 variants with similar packages but different voltage thresholds, such as MAX6315US29D2-T or MAX6315US30D2-T. Cross-reference with MAX6314 series if bidirectional reset outputs are acceptable.
