Product details

The Maxim Integrated MAX44269EWL+T is a dual general-purpose comparator with open-drain outputs, supplied in a 9-bump WLP measuring 1.29 x 1.29 mm. It operates from a single supply between 1.8 V and 5.5 V, drawing a maximum quiescent current of 1 µA. Built-in 6 mV hysteresis eliminates output oscillation near the trip point. This part is suited for battery-powered threshold detection, zero-crossing detectors, and level-shifting circuits where board space is at a premium and power budget is tight.

1 µA quiescent current — the spec that drives the BOM decision

At 1 µA max quiescent current, this comparator is designed for always-on or duty-cycled portable and IoT applications. The open-drain outputs allow wired-OR configurations and level translation to a higher pull-up voltage, which is useful when the comparator output must drive a logic input at a different supply rail.

Package and footprint — what to expect for assembly

The 9-WLP (Wafer-Level Package) is a 1.29 x 1.29 mm array of solder bumps. It is a surface-mount device intended for direct PCB attach. The small footprint means the board layout must accommodate fine-pitch routing and a solder-mask-defined pad pattern.

Frequently asked questions

Is MAX44269EWL+T compatible with 1.8V logic?

Yes, the supply range of 1.8 V to 5.5 V covers 1.8 V logic rails directly. The open-drain outputs can be pulled up to any voltage within that range, making it compatible with 1.8 V, 2.5 V, 3.3 V, or 5 V logic families.

What is the footprint of MAX44269EWL+T?

The device is supplied in a 9-bump WLP (Wafer-Level Package) with a body size of 1.29 x 1.29 mm. The exact bump pitch and pad layout are defined in the datasheet; the footprint is a 3x3 array of solder bumps.

What is an equivalent for MAX44269EWL+T?

No direct pin-compatible equivalent is listed in the available records. The MAX44269EWL+T is distinguished by its combination of ultra-low 1 µA quiescent current, 6 mV built-in hysteresis, and tiny 9-WLP package. For a different package or higher drive, consider other dual open-drain comparators in the Maxim portfolio, but verify pin compatibility.
