MAX16039PLA46+T

Supervisors Overview

The MAX16039PLA46+T is a voltage supervisory circuit designed for low-power battery-backup applications. It operates within a supply voltage range of 0 V to 5.5 V and features a 2.93 V threshold voltage with a 280 ms reset delay time. The device provides an active low, open-drain output and includes a dedicated backup switch function. It consumes only 22 uA of operating power current and supports overvoltage detection at a 3 V threshold. The component is housed in a compact UDFN-8 package and functions reliably across an industrial temperature range from -40 C to +85 C.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and threshold specifications. Confirm RoHS compliance status through the manufacturer datasheet. Check current availability as distribution channels may list limited stock or end-of-life status. Ensure the UDFN-8 package footprint matches your PCB design requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a low-profile supervisory circuit with integrated battery backup switching is required. The 2.93 V threshold suits specific logic level monitoring needs. Consider the 22 uA current draw for battery-operated designs. Verify that the UDFN-8 package dimensions fit the available board space constraints compared to larger packages like SOT-23.
