MAX16020LTET+

Supervisors Overview

The MAX16020LTET+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.53 V 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 push-pull 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, with a typical operating supply current of 1.2 uA. It supports power failure detection and includes a chip enable signal for gating functionality.

Supervisors Feature Summary

• Integrates a watchdog timer and battery backup switch for comprehensive system supervision
• Features chip-enable gating to minimize power consumption during inactive states
• Provides multiple output configurations including active high, active low, and push-pull types

Supervisors Applications

• Low-power microprocessor systems requiring reliable voltage supervision
• Battery-operated devices utilizing backup power switching mechanisms
• Industrial control applications needing watchdog timer protection

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific package marking details against official datasheets. Check for restricted availability or limited stock conditions as indicated by supplier listings. Ensure the ordering suffix matches the required pin configuration and temperature grade specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing systems that require ultra-low quiescent current alongside robust supervisory functions. The inclusion of a watchdog timer and battery backup switch makes it suitable for critical applications where data integrity must be maintained during power transitions. Evaluate the need for chip-enable gating if extended battery life is a primary design constraint compared to standard supervisory circuits.

Supervisors Part Context

This part belongs to the MAX16020 series of low-power microprocessor supervisory circuits. It is designed to monitor voltage levels and provide reset signals to protect microprocessors from improper system operation. The LTET+ designation indicates a specific thermal pad variant in a TQFN-EP-16 package, optimized for surface-mount assembly and efficient heat dissipation in compact electronic designs.
