ADM803TAKSZ-REEL

Supervisors Overview

The ADM803TAKSZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply rails in electronic systems. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed threshold voltage of 2.32 V with an accuracy of 1.5%. The device provides a reset delay time of 240 ms and draws a typical operating supply current of 35 uA. It is housed in a compact SC-70-3 surface-mount package and supports an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset signals when monitored voltage drops below the specified threshold
• Features low quiescent current consumption suitable for battery-powered applications
• Includes a fixed reset delay timer to ensure stable power-up sequencing

Supervisors Applications

• Microprocessor power supply supervision
• Battery-operated portable devices
• Industrial control systems requiring voltage monitoring

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as 'REEL' indicates tape-and-reel packaging while specific letters like 'Z' denote lead-free status. Confirm availability through authorized distributors, as stock levels fluctuate. Ensure the component matches the required SC-70-3 package and 2.32 V threshold specifications for your design.

Supervisors Selection Notes

Select this component when a fixed 2.32 V threshold is required for single-channel voltage monitoring. Consider the 35 uA supply current and 240 ms reset delay for timing-sensitive designs. Verify that the SC-70-3 package fits the board space constraints and that the -40°C to +125°C temperature range meets environmental requirements.

Supervisors Part Context

This part belongs to the ADM803 series of microprocessor supervisors from Analog Devices. These circuits are designed to provide reset signals for digital logic and microcontrollers. The series offers various threshold voltages and packages to accommodate different system voltage levels and form factor requirements.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the ADM803 family with different threshold voltages if system voltage changes. Verify functional equivalence with other single-channel supervisors offering similar reset delays and low current consumption.
