MAX16020LTER+

Supervisors Overview

The MAX16020LTER+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. 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 provides manual reset capability, includes a watchdog timer, and supports battery backup switching. It utilizes a TQFN-16 package with an active high, active low, and open drain output configuration. The reset delay time is specified at 215 ms, and the quiescent current is 3.4 uA. It functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports battery backup switching for continuous operation during power transitions
• Provides manual reset functionality for user-initiated control

Supervisors Applications

• Microprocessor supervisory circuits in embedded systems
• Low-power portable electronic devices requiring voltage monitoring
• Battery-operated equipment needing backup power management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check for obsolescence notices or lifecycle changes as availability may be restricted. Ensure packaging specifications match design integration needs.

Supervisors Selection Notes

Select this component when low quiescent current and integrated watchdog functionality are required. Verify that the 3.1 V threshold aligns with the monitored rail voltage. Ensure the TQFN-16 package fits the PCB layout constraints. Confirm compatibility with the system's operating temperature range and reset timing requirements.

Supervisors Part Context

This part belongs to the MAX16020 series of supervisory circuits designed for low-power applications. It complements other Maxim Integrated PMIC solutions by providing essential voltage monitoring and reset generation capabilities.
