Product details

Single comparator with a built-in voltage reference

The built-in ±3 mV hysteresis eliminates the need for external positive feedback resistors, simplifying the layout in noisy environments such as industrial sensor interfaces or battery-monitoring systems.

450 ns propagation delay — timing budget for loop control

The 450 ns maximum propagation delay sets the comparator's response in applications like overcurrent detection or zero-crossing circuits. The 8 mA typical output current drives logic inputs or small relays directly, though heavier loads will need a buffer.

SOT-23-6 package — footprint and sourcing

Housed in a 6-pin SOT-23-6 (SOT-6) package, the MAX9051AEUT+T occupies a compact footprint suited for space-constrained PCBs in portable or handheld equipment.

Active lifecycle — no imminent EOL concern

For dual-sourcing flexibility, the pin-compatible MAX9050 (without the internal reference) is a functional alternative when an external reference is already on the board.

Frequently asked questions

What is the closest pin-compatible alternative to MAX9051AEUT+T?

The MAX9050 is a pin-compatible comparator without the integrated voltage reference. If your design already has an external reference, the MAX9050 can serve as a drop-in substitute. For a direct replacement with the internal reference, no exact second-source is listed; the MAX9051AEUT+T is the sole variant with the reference.
