ADM810SAKS-REEL7

Supervisors Overview

The ADM810SAKS-REEL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single voltage input. It operates within a supply voltage range of 1 V to 5.5 V and features a push-pull output driver with high-level active reset functionality. The device provides threshold voltages of 2.5 V, 3 V, 3.3 V, and 5 V, with specific variants like the SAKS suffix indicating a 3.0 V threshold (min 2.93 V, max 3.05 V). Key electrical parameters include a maximum reset delay time of 840 ms, an operating current of 60 uA, and an overvoltage threshold of 4.45 V. It supports a wide operating temperature range from -40°C to +125°C and is housed in a compact SC-70-3 surface-mount package.

Supervisors Feature Summary

• Provides reliable power supervision for microprocessors and digital systems through continuous voltage monitoring.
• Features a push-pull output driver capable of sourcing and sinking current for robust reset signal generation.
• Offers manual reset capability to allow external control over the reset state when required.
• Designed for low-power applications with minimal operating current consumption during normal operation.

Supervisors Applications

• Microprocessor system reset generation
• Battery-powered device power management
• Embedded system voltage supervision
• Industrial control unit power monitoring

Supervisors Procurement Notes

Verify the exact threshold voltage variant required, as the ADM810 series includes multiple options (2.5V, 3V, 3.3V, 5V). Confirm the package type matches the design footprint, specifically the SC-70-3 configuration. Check component availability status, as some variants may be discontinued or have limited stock. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the datasheet specifications for reset delay times and accuracy to ensure compatibility with system timing constraints.

Supervisors Selection Notes

Select this component based on the specific supply voltage level of the monitored rail, choosing the appropriate threshold variant (e.g., 3.0 V for 3.3 V systems). Consider the reset delay time requirements; if faster response is needed, other models in the series with shorter delays may be more suitable. Evaluate the package size constraints, as the SC-70-3 form factor is ideal for space-limited designs. Assess the operating temperature range to ensure reliability in extreme environments. Compare the operating current against power budget constraints, especially for battery-operated devices where low quiescent current is critical.

Supervisors Part Context

The ADM810 series belongs to Analog Devices' portfolio of voltage supervisory circuits, widely used in consumer electronics, industrial equipment, and communication systems. These components are part of the broader PMIC category, focusing on simple reset and power-fail detection functions. The ADM810SAKS-REEL7 specifically represents a reel-packaged version of the SC-70-3 variant, optimized for automated surface-mount assembly processes. This series is known for its simplicity, low cost, and reliability in basic power monitoring tasks without complex watchdog or backup switch functionalities.

Supervisors Replacement Considerations

Direct substitutes within the same family include ADM810SAKSZ-REEL7 and ADM810MAKSZ-REEL7, which share similar pinouts and functionalities but may differ in threshold voltages or package types. For alternative packages, consider ADM810TARTZ-REEL7 (SOT-23-3) or ADM810RART-REEL7 (SOT-23-3), ensuring threshold and delay specifications match. Always verify electrical parameters and mechanical dimensions before substitution to maintain system integrity.
