MAX16035LLB46+T

Supervisors Overview

The MAX16035LLB46+T is a low-power battery backup circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 0 V to 5.5 V and features an undervoltage threshold of 4.25 V and an overvoltage threshold of 4.5 V. The device monitors a single input and provides an active-low reset signal with a minimum timeout of 140 ms. It draws 22 uA of operating current and dissipates up to 402.8 mW. The component is housed in a 10-UDFN (2x2 mm) package and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides continuous monitoring for battery backup applications with dedicated undervoltage and overvoltage detection thresholds.
• Generates an active-low push-pull reset output to ensure system integrity during power anomalies.
• Designed for minimal power consumption, suitable for energy-constrained portable and battery-operated devices.

Supervisors Applications

• Battery backup systems requiring voltage supervision
• Portable electronic devices with limited power budgets
• Embedded systems needing reliable power-on reset signals

Supervisors Procurement Notes

Verify the specific suffix LLB46+T against the official Maxim Integrated datasheet to confirm the exact voltage thresholds and package type. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices, as availability may vary. Ensure the ordering part number matches the required electrical specifications for your design.

Supervisors Selection Notes

Select this component when a single-channel supervisor with precise 4.25 V/4.5 V thresholds is required. Consider the 10-UDFN package size for space-constrained PCB layouts. Evaluate the 22 uA quiescent current against system power requirements. Verify that the active-low reset polarity and 140 ms timeout meet the target microcontroller or logic interface timing constraints.

Supervisors Part Context

This part belongs to the MAX16035 series of low-power battery backup circuits. The series offers various threshold voltages and package options to suit different monitoring needs. The MAX16035LLB46+T specifically targets applications requiring supervision around the 4.5 V level, commonly associated with lithium-ion or similar battery chemistries.

Supervisors Replacement Considerations

Consult the official MAX16035 datasheet for pin-compatible alternatives within the same family. Verify that any substitute maintains the 10-UDFN footprint and matching voltage thresholds. Cross-reference with other Maxim Integrated supervisors if higher precision or additional channels are needed.
