ADM1816-20AKSZ-RL

Supervisors Overview

The ADM1816-20AKSZ-RL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and monitors a single input channel with a threshold of 2.55 V. The device provides an active low reset signal with a minimum timeout of 100 ms. It features push-pull or open-drain output types and is housed in a compact SC70-3 package measuring 2.00 x 1.25 mm. The component supports surface mount installation and functions reliably across an operating temperature range of -40°C to +105°C.

Supervisors Feature Summary

• Provides reliable system reset generation for microprocessors under varying power conditions
• Offers flexible output configuration supporting both push-pull and open-drain modes
• Ensures stable operation across extended industrial temperature ranges

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Power supply monitoring in portable electronic devices
• Industrial control system supervision

Supervisors Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when ordering. Confirm the exact threshold voltage variant matches the design requirement, as the series includes multiple voltage options. Ensure the SC70-3 package footprint aligns with the PCB layout. Check current availability status as supply may be limited for certain variants.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a 2.55 V threshold is required. Consider the 100 ms minimum reset delay for timing-sensitive applications. The SC70-3 package is suitable for space-constrained designs. Verify compatibility with the target microprocessor's reset input requirements regarding active low polarity and drive capability.

Supervisors Part Context

This part belongs to the ADM1816 family of microprocessor reset circuits from Analog Devices. It shares functional similarities with other members like the ADM1815 and ADM1818 but differs in specific threshold voltages and package options. The family is designed for general-purpose power supervision in digital systems requiring reliable reset sequencing.

Supervisors Replacement Considerations

ADM1816-20AKSZ-RL7 is a confirmed substitute with identical electrical characteristics and pinout. Other ADM1816 variants with different threshold voltages are not direct replacements unless the voltage level matches the application needs.
