ADM1166ASUZ-REEL

Overview

The ADM1166ASUZ-REEL is a programmable supervisor sequencer integrated circuit manufactured by Analog Devices Inc. It operates within an input voltage range of 3V to 14.4V and draws a supply current of 4.2 mA. The device monitors up to ten inputs and features output types including open collector/drain and push-pull configurations. It includes manual reset functionality, a watchdog timer, and a chip enable signal. The component is housed in a 48-TQFP package with dimensions of 7x7 mm and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Programmable sequencing for complex power-up and power-down sequences
• Integrated watchdog timer for system reliability monitoring
• Supports multiple output drive styles including open drain and push-pull

Applications

• Power management systems requiring precise sequence control
• Industrial equipment supervisory circuits
• Embedded systems needing multi-rail power supervision

Procurement Notes

Verify the specific suffix REEL indicates reel packaging when ordering. Confirm the 48-TQFP package type matches your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for RoHS compliance status prior to integration. Validate that the 14.4V maximum input rating aligns with your supply rails.

Selection Notes

Select this component when designing systems requiring independent monitoring of multiple voltage rails. The programmable nature allows customization of delay times and thresholds. Consider the 4.2 mA supply current impact on overall system efficiency. The TQFP package offers surface mount convenience for automated assembly processes.
