Analog Devices Inc./Maxim Integrated MAX8211MTV

Overview

MAX8211MTV from Maxim Integrated is a CMOS micropower voltage detector IC designed to monitor supply rails and warn microprocessors of undervoltage conditions. It features a 1.15V internal bandgap reference, ±40mV threshold accuracy (±3.5%), 7mA current-limited open-drain output sink, and operates across a 2.0V to 16.5V supply range. Used in logic-supply undervoltage detection circuits with external resistor dividers.

For engineers reviewing the MAX8211MTV datasheet, MAX8211MTV pinout, MAX8211MTV application, or MAX8211MTV equivalent, this device serves as a precision, low-quiescent-current (5µA) replacement for bipolar ICL8211 in high-reliability industrial and military systems requiring -55°C to +125°C operation and TO-99 hermetic packaging.

Technical Context

The MAX8211MTV integrates a comparator, 1.15V bandgap reference, open-drain n-channel output transistor, and open-drain p-channel hysteresis output. Its THRESH pin detects input voltage relative to the internal reference: output sinks current when THRESH < 1.15V. Hysteresis is implemented via positive feedback through the HYST pin, enabling noise-immune switching.

Unlike the MAX8212 variant, the MAX8211MTV provides a current-limited 7mA (typical) output sink-sufficient to directly drive LEDs without series resistors. It supports programmable trip voltages using two external resistors and delivers ±0.1mV disparity between OUT and HYST switching thresholds to eliminate chatter.

FAQ

What is the function of the HYST pin on the MAX8211MTV?

The HYST pin on the MAX8211MTV is an open-drain p-channel output used to inject positive feedback into the THRESH node via an external resistor. This creates user-programmable hysteresis-preventing output chatter during slow or noisy voltage transitions. When THRESH exceeds 1.15V, HYST activates and raises the effective trip threshold, establishing a clean dead-band. The MAX8211MTV achieves just 0.1mV disparity between HYST and OUT switching points, ensuring precise, stable behavior.

Does the MAX8211MTV require external components to operate?

Yes-the MAX8211MTV requires at least two external resistors (R1 and R2) to form a voltage divider that sets the trip point at the THRESH pin relative to its 1.15V internal reference. A third resistor (R3) is optional but recommended to enable hysteresis via the HYST pin. No external capacitors or biasing networks are needed. The MAX8211MTV's 5µA quiescent current and high-impedance THRESH input allow use of MΩ-range resistors, minimizing system power draw.

What is the maximum output sink current of the MAX8211MTV?

The MAX8211MTV provides a current-limited open-drain output sink with a typical value of 7mA and a hard limit of 30mA under any condition (per datasheet Note 1). This built-in current limiting allows direct drive of LEDs, optocouplers, or logic inputs without series resistors-reducing BOM count and PCB area. The output saturation voltage remains ≤0.4V at 2mA, ensuring strong logic-low assertion even under load.

Can the MAX8211MTV be used for overvoltage detection?

No-the MAX8211MTV is configured exclusively for undervoltage detection: its OUT pin activates (pulls low) when the THRESH pin voltage falls below 1.15V. For overvoltage detection, the MAX8212MTV variant must be used, as it triggers when THRESH exceeds 1.15V. While both share identical pinouts and packages, their internal comparator polarity differs fundamentally; substituting one for the other without circuit redesign will invert detection logic and cause functional failure.

What does the "TV" suffix indicate in MAX8211MTV?

The "TV" suffix in MAX8211MTV denotes Maxim's TO-99 metal-can package with case connected to Pin 7, qualified for the -55°C to +125°C military temperature range. Unlike plastic or SO packages, the TO-99 provides hermetic sealing, superior thermal conductivity, and enhanced EMI shielding-critical for avionics, downhole tools, and space-qualified electronics. The "M" prefix confirms military-grade screening and testing per MIL-STD-883 requirements.
