Applications
MAX811TEUS+T is used in microcontroller reset circuits for industrial PLCs, embedded computers, and handheld instruments where a reliable active-low reset signal is needed during power ramp-up and supply brownouts. Its manual reset input also makes it suitable for front-panel reset buttons in set-top boxes, routers, and medical devices that must reinitialize the processor on demand without additional logic.

Frequently Asked Questions
What supply voltage range does MAX811TEUS+T support for monitoring 1.8 V and 3.3 V processor rails?
The MAX811TEUS+T operates from 1.2 V to 5.5 V VCC, which covers common processor supply rails including 1.8 V, 2.5 V, 3.3 V, and 5 V. This wide range allows a single part to be designed into multiple product variants that use different logic supply voltages without changing the supervisor component.
How does the manual reset feature of MAX811TEUS+T benefit system designs with a front-panel reset button?
The manual reset input allows an external pushbutton to assert the active-low reset output immediately, pulling the processor RESET line low for a debounced period without requiring additional logic or firmware. This simplifies circuit design and eliminates bounce-related spurious resets in systems using 4-pin SOT-23 footprint constraints.
What is the body size of the 4-pin SOT-23 package used by MAX811TEUS+T and how does it fit into compact PCB layouts?
The SOT-23-4 package body measures approximately 2.9 mm x 1.6 mm with 0.95 mm pin pitch, one of the smallest surface-mount packages for supervisor ICs. This allows the MAX811TEUS+T to be placed within a 4 mm x 3 mm keep-out zone adjacent to the processor VCC decoupling capacitors on a densely routed 4-layer PCB.
Does MAX811TEUS+T carry REACH and RoHS compliance for restricted-substance procurement requirements?
Yes. The MAX811TEUS+T carries a REACH-compliant code and an e3 JESD-609 lead-free solderability rating, confirming it meets RoHS Directive 2011/65/EU requirements for restricted substances including lead below 1000 ppm. These certifications support CE marking and EU import compliance for industrial and consumer electronics assemblies.
