ADM6348-45ARTZ-R7

Supervisors Overview

The ADM6348-45ARTZ-R7 is an ultralow power microprocessor reset circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.5 V for monitoring input lines. The device provides an active-low open-drain output with a reset delay time of 185 ms. Designed for surface-mount installation, it utilizes a compact SOT-23-3 package. The component functions without manual reset or watchdog timer capabilities, ensuring reliable system supervision in applications requiring low quiescent current consumption.

Supervisors Feature Summary

• Ultralow power consumption suitable for battery-operated systems
• Fixed 4.5 V threshold voltage for precise power line monitoring
• Active-low open-drain output configuration for flexible interfacing
• Compact three-lead SOT-23 surface-mount packaging

Supervisors Applications

• Microprocessor system supervision
• Battery-powered portable electronics
• Handheld communication devices
• Industrial control system power monitoring

Supervisors Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the 4.5 V threshold matches the target supply rail requirements. Check RoHS compliance status against current regulatory standards. Ensure the open-drain output logic aligns with the downstream controller input specifications. Validate availability through authorized distributors as lifecycle status may vary.

Supervisors Selection Notes

Select this component when a fixed 4.5 V supervisory threshold is required for systems operating up to 5.5 V. The open-drain output necessitates an external pull-up resistor; ensure the resistor value supports the desired rise time and voltage level. Consider the 185 ms reset delay to verify compatibility with the target processor's startup sequence. The SOT-23-3 package limits thermal dissipation, so maintain operation within the specified -40°C to +85°C temperature range.

Supervisors Part Context

This part belongs to the ADM6348 series of ultralow power reset circuits from Analog Devices. The series offers various threshold voltages to accommodate different supply rails while maintaining consistent low-power characteristics. The ADM6348 variant specifically provides an open-drain output, distinguishing it from push-pull output counterparts like the ADM6346. This family is designed for cost-sensitive applications requiring minimal standby current.

Supervisors Replacement Considerations

Direct substitutes include other ADM6348 variants with different threshold voltages, such as ADM6348-33ARTZ-R7 for 3.3 V systems. Cross-family replacements like the ADM6346-45ARTZ-R7 offer similar electrical performance but feature a push-pull output instead of open-drain. Verify pinout compatibility and output drive requirements before substituting.
