MAX16033PLB44+T

Supervisors Overview

The MAX16033PLB44+T is a low-power battery-backup supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 0 V to 5.5 V and features an undervoltage threshold of 2.85 V and an overvoltage threshold of 3 V. The device provides manual reset functionality with a reset delay time of 280 ms. It includes a battery backup switch for seamless power transition monitoring. The component is housed in a UDFN-10 surface-mount package and draws a typical operating supply current of 22 uA.

Supervisors Feature Summary

• Integrates battery backup switching capability to monitor power source transitions
• Provides manual reset input for system control flexibility
• Features active-low open-drain output for interface compatibility

Supervisors Applications

• Battery-powered portable electronic devices requiring power supervision
• Systems utilizing battery backup switches for uninterrupted operation
• Low-power embedded applications needing voltage monitoring

Supervisors Procurement Notes

Verify the exact suffix PLB44 against official datasheets to confirm specific threshold voltages, as variations exist within the MAX16033 family. Confirm RoHS compliance status through manufacturer documentation. Check current lifecycle status, as availability may be limited or discontinued depending on the region and distributor.

Supervisors Selection Notes

Select this component when a dedicated battery backup supervisor is required alongside standard voltage monitoring. Ensure the 2.85 V undervoltage and 3 V overvoltage thresholds align with the target power rails. Consider the UDFN-10 package size constraints and the 22 uA quiescent current requirement for battery life calculations.

Supervisors Part Context

This part belongs to the MAX16033 series of low-power battery-backup circuits designed for small DFN packages. It complements other Maxim Integrated supervisory solutions by offering combined undervoltage/overvoltage detection with battery swap monitoring capabilities in a compact form factor suitable for space-constrained designs.

Supervisors Replacement Considerations

Consult official substitution guides for compatible parts within the MAX16033 series or similar low-power supervisors. Verify pinout compatibility and electrical parameter alignment before considering alternative manufacturers.
