Product details
Overview
MAX16011TAB+T from Analog Devices is an ultra-small, low-power dual-comparator overvoltage/undervoltage protection IC for high-voltage systems. It features independent INA+/INB- inputs, open-drain OUTA/OUTB outputs rated to 72V, active-high EN input, and LOGIC-selectable OUTB polarity. Designed for telecom 48V power rails and multicell battery stacks, it delivers window detection with 5% hysteresis and operates across -40°C to +125°C.
For engineers reviewing the MAX16011TAB+T datasheet, MAX16011TAB+T pinout, MAX16011TAB+T application, or MAX16011TAB+T equivalent, this page provides verified functional context, validated pin roles, confirmed thermal and electrical specs, and real-world selection guidance for industrial and telecom overvoltage monitoring circuits.
Technical Context
The MAX16011TAB+T implements two independent voltage comparators with internal 1.245V threshold reference (±0.015V), 5% hysteresis, and fast 2μs propagation delay. Its EN input enables both comparators simultaneously, while the LOGIC pin configures OUTB logic polarity-low when INB- exceeds VTH+ (LOGIC = GND) or high when INB- exceeds VTH+ (LOGIC = VCC).
It integrates undervoltage lockout (UVLO) at 5.0V (±0.25V), supports supply voltages from 5.5V to 72V, and drives open-drain outputs capable of sinking 3.2mA at VOL ≤ 0.4V. All inputs (INA+, INB-, EN, LOGIC) tolerate up to +12V, and outputs (OUTA, OUTB) withstand up to +80V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5V to 72V - Enables direct monitoring of 48V telecom rails, 60V battery stacks, and server PSUs without external regulators. |
| Threshold Voltage (VTH+) | 1.245V ±0.015V - Precision internal reference used with external resistor dividers to set custom UV/OV trip points. |
| Hysteresis | 5.0% - Configured by part suffix 'B'; prevents chatter during noisy transients near trip thresholds in industrial environments. |
| Propagation Delay | 2μs max - Ensures rapid fault response for protecting downstream DC-DC converters and FPGAs from overvoltage events. |
| UVLO Threshold | 5.0V ±0.25V - Disables outputs below safe operating voltage, preventing false triggers during brownout or startup. |
| Output Drive Capability | Open-drain, 72V tolerant, 3.2mA sink - Allows direct interface to 24V/48V PLC I/O lines or optocoupler inputs without level-shifting. |
| Operating Temperature | -40°C to +125°C - Fully specified for under-hood automotive auxiliary modules and industrial control cabinets. |
Pinout & Package
MAX16011TAB+T is housed in a thermally enhanced 8-pin TDFN package (3mm × 3mm, 0.5mm pitch) with exposed pad (EP) for improved heat dissipation and EMI performance. The package is RoHS-compliant and lead(Pb)-free.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INA+ | Noninverting input for undervoltage comparator; tied to resistor divider to detect VCC drop below lower threshold. |
| 2 | OUTA | Open-drain undervoltage output; pulled low when INA+ falls below VTH− (1.18V), signaling brownout condition. |
| 3 | EN | Active-high enable input; must be ≥1.4V to activate comparators; internally pulled down to GND if unused. |
| 4 | OUTB | Open-drain overvoltage output; polarity selectable via LOGIC pin; asserts on INB- > VTH+ (1.245V). |
| 5 | INB- | Inverting input for overvoltage comparator; connected to resistor divider to monitor rising VCC or battery voltage. |
| 6 | VCC | Main supply input (5.5V–72V); powers internal regulator and logic; requires 0.1µF bypass to GND. |
| 7 | GND | Analog/digital ground reference; EP must be soldered to PCB ground plane for thermal and noise integrity. |
| 8 | LOGIC | OUTB logic select input; GND = active-low OUTB, VCC = active-high OUTB; enables flexible system-level fault signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent comparators | Enables simultaneous undervoltage (OUTA) and overvoltage (OUTB) monitoring on same rail - eliminates need for two discrete supervisors. |
| 5% hysteresis (suffix B) | Provides robust noise immunity in electrically noisy telecom and industrial settings without external RC networks. |
| 72V-tolerant open-drain outputs | Directly interfaces with 24V/48V control logic or optocouplers - no external level shifters or clamping diodes required. |
| LOGIC-selectable OUTB polarity | Supports both active-low and active-high fault reporting in same design - simplifies integration with legacy or new MCU GPIOs. |
| Ultra-low quiescent current | 25–40µA across 12–48V supply range - extends battery life in always-on monitoring applications like remote sensors. |
Applications
| 48V Telecom Power Monitoring | Industrial PLC Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-threshold voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16010TAB+T | Complementary EN/EN enable inputs instead of single EN; no LOGIC pin - fixed active-low OUTB polarity. | Suitable where system-level enable logic uses push-pull drivers or requires guaranteed low-state disable behavior. | Select MAX16010TAB+T only if complementary enable signals exist; otherwise MAX16011TAB+T offers greater flexibility with single EN and configurable OUTB. |
| TLV809E33DBZR | Single-channel 3.3V reset IC with 200ms delay; no adjustable threshold, no hysteresis selection, no 72V tolerance. | Limited to low-voltage microcontroller reset; cannot replace MAX16011TAB+T in high-voltage monitoring roles. | TLV809E33DBZR is not functionally equivalent - use only for basic 3.3V supply monitoring; MAX16011TAB+T remains required for 5.5–72V window detection. |
Compared with MAX16010TAB+T, MAX16011TAB+T trades complementary enable for LOGIC-configurable output polarity - simplifying control logic in new designs. Compared with TLV809E33DBZR, it delivers full high-voltage window detection capability, making it irreplaceable in telecom and industrial power supervision.

FAQ
What is the exact hysteresis value for MAX16011TAB+T?
The 'B' suffix in MAX16011TAB+T specifies 5.0% hysteresis, corresponding to a threshold spread of approximately 62mV around the 1.245V nominal VTH+. This is confirmed in the Electrical Characteristics table under "Threshold-Voltage Hysteresis" and applies across the full -40°C to +125°C operating range. The hysteresis is factory-trimmed and does not require external components.
Can MAX16011TAB+T monitor both overvoltage and undervoltage on the same input rail?
Yes, MAX16011TAB+T performs true window detection using INA+ for undervoltage and INB- for overvoltage on the same monitored rail. By connecting both inputs to the same resistor divider network, it generates independent OUTA (low on UV) and OUTB (configurable on OV) signals - enabling precise band-based supervision without additional ICs.
What is the maximum voltage the OUTA and OUTB pins can safely withstand?
Per Absolute Maximum Ratings, OUTA and OUTB pins tolerate -0.3V to +80V relative to GND. This 72V operational rating (with 8V margin) allows direct connection to 48V telecom buses and 60V battery systems without external clamping. The 2μs propagation delay ensures fast response even during fast-rising transients.
How does the LOGIC pin affect MAX16011TAB+T behavior?
The LOGIC pin selects OUTB polarity: when tied to GND, OUTB goes low on overvoltage (active-low); when tied to VCC, OUTB goes high on overvoltage (active-high). This is documented in Table 2 ("MAX16011 Output Logic") and enables compatibility with both legacy interrupt controllers expecting low-active faults and modern MCUs preferring high-active signaling.
Is MAX16011TAB+T pin-compatible with other devices in the MAX16010–MAX16014 family?
MAX16011TAB+T shares the same 8-pin TDFN package and pinout as MAX16010TAB+T (pins 1–8 identical), but differs from MAX16012–MAX16014 which use 6-pin packages. Pin compatibility with MAX16010TAB+T allows drop-in substitution where complementary enable is not required - however, LOGIC functionality is unique to MAX16011TAB+T.
