MAX9038BABT+T

Overview

The MAX9038BABT+T is a micropower, single-supply analog comparator integrated with a precision voltage reference. It operates within a supply voltage range of 2.5V to 5.5V and consumes only 40μA of quiescent current. The device features rail-to-rail inputs and outputs, with an open-drain output stage capable of sinking and sourcing up to 8mA. It includes internal hysteresis of ±3mV and exhibits a propagation delay of 400ns. The integrated reference provides a fixed output voltage of 1.23V with an initial accuracy of ±0.4%.

Feature Summary

• Integrates a low-power comparator with a precision voltage reference in a compact UCSP package.
• Features rail-to-rail input and output stages for compatibility with various logic levels.
• Includes internal hysteresis to ensure clean switching transitions even with slow-moving signals.
• Open-drain output design minimizes supply current surges during switching events.

Applications

• Precision battery management systems
• Window comparator circuits
• IR receivers
• Level translators

Procurement Notes

Verify the specific suffix 'B' indicates the B grade with 1% initial accuracy and 100ppm/°C temperature coefficient, distinct from the A grade. Confirm the '+T' designation corresponds to the reel packaging format. Ensure the component matches the UCSP-6 pinout configuration before integration into the design.

Selection Notes

Select this component when a single-channel comparator with an integrated reference is required in space-constrained designs. It is suitable for applications needing rail-to-rail operation and low power consumption. Consider the open-drain output capability if level translation or wired-OR configurations are necessary within the system architecture.

Part Context

This part belongs to the MAX9038–MAX9043/MAX9050–MAX9053 family of micropower comparators. These devices combine low-voltage comparators with precision references, designed for both 3V and 5V systems. The MAX9038 specifically offers a single comparator with a 1.23V reference in a 6-bump UCSP package.

Replacement Considerations

The MAX9039BEBT+T serves as a functional substitute within the same series, sharing identical electrical characteristics and package dimensions while maintaining the 1.23V reference output.
