MAX16020PTET+T

Supervisors Overview

The MAX16020PTET+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 3.1 V. The device monitors one input and provides active high, active low, and open drain outputs. Key functional parameters include a manual reset capability, an integrated watchdog timer, and a battery backup switch. The reset delay time is specified at 215 ms, while the quiescent current is 3.4 uA. It supports chip enable signaling and power failure detection. The component is housed in a TQFN-16 package and functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited stock or restricted supply conditions. Confirm that the specific suffix denotes tape-and-reel packaging if required for automated assembly. Ensure compatibility with existing board designs regarding the TQFN-16 footprint and thermal requirements. Cross-reference the manufacturer's latest documentation for any updates on lead times or end-of-life notifications before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with integrated watchdog and battery backup capabilities is required. The low quiescent current makes it suitable for battery-operated applications. Verify that the 3.1 V threshold aligns with the monitored rail voltage. Consider the TQFN-16 package size relative to available PCB space. Ensure the operating temperature range meets the environmental specifications of the target application.
