ADM6316BX30ARJZ-R7

Supervisors Overview

The ADM6316BX30ARJZ-R7 is a supervisory circuit from Analog Devices Inc. housed in a 5-lead SOT-23 package. It monitors power supply voltage with a fixed reset threshold of 3.0V, selected from 26 options ranging from 2.5V to 5V in 100mV increments. The device features a manual reset input and offers four configurable reset timeout options: 1ms, 20ms, 140ms, and 1120ms (minimum). It includes a watchdog timer with typical timeout options of 6.3ms, 102ms, 1600ms, and 25.6s. The part operates within an industrial temperature range of -40°C to +85°C, consumes low power (5μA), and guarantees valid reset output down to VCC = 1V.

Supervisors Feature Summary

• Integrates power-on reset generation with a watchdog timer for code execution integrity monitoring
• Includes a dedicated manual reset input allowing external assertion of the reset signal
• Provides glitch immunity against power supply transients during operation

Supervisors Applications

• Microprocessor systems requiring reliable power supervision
• Controllers needing watchdog functionality for fault recovery
• Portable equipment demanding low power consumption
• Intelligent instruments operating in industrial environments

Supervisors Procurement Notes

Verify the specific suffix 'BX30' corresponds to the 3.0V threshold and required output stage configuration before procurement. Confirm the 'RJZ-R7' designation matches the intended tape-and-reel packaging requirements. Ensure the component meets RoHS compliance standards as indicated by the manufacturer documentation. Cross-reference the exact part number with official Analog Devices catalogs to avoid substitution errors due to similar family members.

Supervisors Selection Notes

Select this component when a fixed 3.0V reset threshold is required alongside manual reset capability. Consider the available watchdog timeout options if system timing constraints demand specific detection periods. Evaluate the push-pull or open-drain output stage needs against load requirements. Verify that the 5μA quiescent current fits within the system's power budget constraints.

Supervisors Part Context

This part belongs to the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322 family of supervisory circuits. These devices share common architectural features including integrated watchdog timers and manual reset inputs. Variations within the family differ primarily in reset threshold voltages, output stage configurations, and the presence or absence of specific inputs like the watchdog strobe pin.
