ADM6346-33ARTZ-R7

Supervisors Overview

The ADM6346-33ARTZ-R7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply voltages in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 3.3 V to detect under-voltage conditions. The device utilizes an SOT-23-3 surface-mount package, ensuring compact integration into space-constrained designs. It provides a push-pull output type for driving reset lines directly without additional components. The reset delay time is specified at 20 us, facilitating rapid response to power anomalies. The component supports a minimum operating temperature range extending down to -40 C, suitable for industrial applications.

• Push-pull output capability eliminates need for external pull-up resistors

Supervisors Applications

• Microprocessor system reset circuits
• Battery-powered portable electronics
• Industrial control board power supervision

Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprint requirements for the SOT-23-3 package. Confirm that the fixed 3.3 V threshold aligns with the target system's logic levels and reset requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a low-power, single-channel voltage monitor with a precise 3.3 V threshold is required. Consider the push-pull output feature if minimizing external passive components is a priority. Evaluate the 20 us reset delay against the specific timing constraints of the target microprocessor or FPGA to ensure reliable system initialization during power-up events.

Supervisors Part Context

This component belongs to the ADM6346 series of ultra-low power reset circuits from Analog Devices. The series offers various threshold options to accommodate different voltage rails. The ARTZ suffix indicates a specific tape and reel packaging format compatible with automated surface-mount assembly processes, distinguishing it from tube or bulk packaging variants within the same functional family.
