ADM6348-33ARTZ-R7

Supervisors Overview

The ADM6348-33ARTZ-R7 is a supervisory voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.3 V for power supply monitoring. The device provides an active-low open-drain reset output with a typical reset delay time of 185 ms. Designed for surface-mount installation, it is housed in a compact SOT-23-3 package. The component functions without manual reset capabilities or integrated watchdog timers, ensuring reliable system supervision under varying thermal conditions.

Supervisors Feature Summary

• Provides continuous monitoring of the main power supply rail to detect undervoltage conditions
• Generates a reset signal via an active-low open-drain output interface
• Operates with ultra-low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Portable electronic devices requiring low standby current
• Industrial control systems needing reliable voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix ARTZ-R7 against official Analog Devices documentation to confirm pinout compatibility and temperature grade. Confirm that the open-drain output configuration matches the target circuit design requirements. Check for obsolescence status as distribution availability may be limited for this specific revision.

Supervisors Selection Notes

Select this component when a fixed 3.3 V threshold is required for system supervision. Ensure the application can accommodate the 185 ms reset delay time during power-up sequences. Verify that the open-drain output architecture aligns with the pull-up resistor strategy used in the host system design.

Supervisors Part Context

This part belongs to the ADM6348 series of ultralow power reset circuits from Analog Devices. The series offers various threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V options. All variants share similar packaging and functional characteristics but differ in their specific trip points for different logic families.

Supervisors Replacement Considerations

Other parts in the ADM6348 family with different threshold voltages may serve as functional substitutes if the voltage level is adjusted accordingly. Cross-reference with ADM6348-30ARTZ-R7 or ADM6348-25ARTZ-R7 for alternative thresholds.
