ADM811-3TARTZ-RL7

Supervisors Overview

The ADM811-3TARTZ-RL7 is a micropower voltage supervisor with an open-drain reset output. It monitors supply voltage and asserts a reset signal when the input falls below a precise threshold of 2.93V. The device features a fixed delay time to ensure stability during power-up. It operates from a single supply ranging from 1.6V to 5.5V, consuming minimal quiescent current. The component is housed in a compact SOT-23 package, suitable for space-constrained portable electronics.

Supervisors Feature Summary

• Provides reliable system reset by monitoring supply voltage levels
• Features low quiescent current consumption for battery-powered applications
• Includes a fixed delay timer to prevent false resets during power transitions

Supervisors Applications

• Portable consumer electronics requiring low power management
• Microcontroller and DSP system supervision
• Battery-operated devices needing voltage level monitoring

Supervisors Procurement Notes

Verify the specific suffix ARTZ indicates the temperature range and packaging configuration. Confirm the RL7 designation matches the required reel quantity and tape-and-reel specifications for your manufacturing process. Ensure compatibility with your assembly equipment regarding the SOT-23 footprint.

Supervisors Selection Notes

Select this component when a fixed threshold near 3V is required for system supervision. Consider the fixed delay characteristic if external timing adjustments are not feasible. Evaluate the quiescent current against strict battery life requirements. Verify that the open-drain output interface aligns with the downstream logic voltage levels.

Supervisors Part Context

This part belongs to the ADM811 family of micropower voltage supervisors. These devices are designed for applications where low power consumption and small size are critical. The family offers various threshold voltages and delay options to suit different system requirements while maintaining high accuracy and reliability.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar threshold voltages. Verify that any substitute maintains the same open-drain output structure and operating voltage range. Ensure thermal and mechanical specifications match the existing design constraints.
