ADM803ZAKS-REEL

Supervisors Overview

The ADM803ZAKS-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a microprocessor supervisor in an SC-70-3 surface-mount package. It features a fixed threshold voltage of 2.32 V and provides an open-drain output type. The device operates within a supply voltage range of 1 V to 5.5 V, with a reset delay time of 240 ms and accuracy of 1.5%. It draws a working supply current of 35 uA and functions across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable power supervision for microprocessor systems through a dedicated voltage monitoring input.
• Features an open-drain output configuration suitable for interfacing with various logic families.
• Operates efficiently with low quiescent current consumption to minimize power usage during standby.

Supervisors Applications

• Microprocessor system reset generation
• Battery-powered equipment power management
• Portable instrumentation supervision

Supervisors Procurement Notes

Verify the specific suffix REEL7 indicates tape and reel packaging when ordering. Confirm the SC-70-3 package compatibility with your PCB footprint. Ensure the 2.32 V threshold aligns with your target supply rail. Check RoHS compliance status if required by your manufacturing standards. Validate lead times as availability may vary by region.

Supervisors Selection Notes

Select this component when a fixed 2.32 V threshold is required for single-supply monitoring. Consider the SC-70-3 package size constraints for compact designs. Evaluate the 35 uA supply current against battery life requirements. Compare the 240 ms reset delay with system startup timing needs. Verify that the open-drain output meets interface requirements without external pull-ups.

Supervisors Part Context

This part belongs to the ADM803 series of supervisory circuits from Analog Devices. It is categorized under PMIC - Power Management ICs. The device serves as a standalone voltage monitor without manual reset or watchdog timer capabilities. It complements other ADM8xx series parts offering different thresholds or packages.

Supervisors Replacement Considerations

Check for ADM803 variants with different threshold voltages if 2.32 V is unsuitable. Consider ADM809 series for push-pull output options. Verify pinout compatibility before substituting with other SC-70-3 supervisors. Consult official cross-reference tools for parametrically similar devices.
