Product details
Overview
MAX16010TAA+T from Analog Devices is an ultra-small, low-power overvoltage/undervoltage protection IC with dual independent comparators, 5.5V–72V supply range, 2µs max propagation delay, 0.5% hysteresis, and open-drain outputs rated to 72V. It operates from –40°C to +125°C in telecom power supervision and battery-stack monitoring systems.
For engineers reviewing the MAX16010TAA+T datasheet, MAX16010TAA+T pinout, MAX16010TAA+T application, or MAX16010TAA+T equivalent, this page delivers verified functional identity, exact pin roles, thermal and electrical specifications, real-world use cases, and two validated alternative parts for window-detection overvoltage/undervoltage protection circuits.
Technical Context
The MAX16010TAA+T implements a dual-comparator architecture with complementary enable inputs (EN/EN) and separate INA+/INB- threshold inputs. Its internal 1.245V reference (±1.5mV over temperature) sets precise trip points for undervoltage (OUTA) and overvoltage (OUTB) detection.
Each comparator features open-drain outputs capable of sinking up to 3.2mA at ≤0.4V low-level voltage, with UVLO activation at 5.0V (±0.25V) and startup response under 100µs. The device uses BiCMOS process technology and integrates internal hysteresis control via factory-trimmed 0.5% hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5V to 72V - supports direct connection to 48V telecom rails, multicell Li-ion stacks, and industrial 24V/48V systems without external regulators. |
| Propagation Delay | 2µs max - enables fast fault response in transient-prone environments like server PSUs and battery management. |
| Threshold Accuracy | 1.245V ±3mV (TYP) - ensures precise window detection with minimal calibration overhead in high-reliability systems. |
| Hysteresis | 0.5% - provides noise immunity against supply ripple and EMI in noisy industrial or telecom backplanes. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive auxiliary modules, base station power supplies, and industrial controllers. |
| Supply Current | 20–40µA - enables always-on monitoring in battery-backed systems with multi-year runtime requirements. |
| UVLO Threshold | 5.0V ±0.25V - prevents false triggering during brown-out conditions while ensuring reliable startup above nominal 5.5V operation. |
Pinout & Package
MAX16010TAA+T is housed in an 8-pin TDFN package (3mm × 3mm, 0.5mm pitch) with exposed pad (EP) connected to GND for thermal and EMI performance. Pin 1 is INA+, pin 2 is OUTA, pin 3 is EN (active-low), pin 4 is INB-, pin 5 is VCC, pin 6 is GND, pin 7 is EN (active-high), and pin 8 is OUTB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA+ | Noninverting input for undervoltage comparator | Monitors falling voltage; asserts OUTA low when input drops below VTH− (1.223V typical) |
| OUTA | Open-drain undervoltage output | Sinks up to 3.2mA; requires external pullup to VCC; used to disable DC-DC converters during brown-out |
| EN | Active-low enable input | Internally pulled up to VCC; drives both outputs low when high; enables monitoring when low |
| INB- | Inverting input for overvoltage comparator | Monitors rising voltage; asserts OUTB low when input exceeds VTH+ (1.245V typical) |
| VCC | Main supply input | Accepts 5.5V–72V; includes internal UVLO and regulator; bypass with ≥0.1µF capacitor recommended |
| GND | Ground reference | Common return for all analog and digital circuitry; must be tied to EP for thermal stability |
| EN | Active-high enable input | Internally pulled down to GND; complements EN for flexible system-level control logic |
| OUTB | Open-drain overvoltage output | Sinks up to 3.2mA; logic polarity fixed unless used with MAX16011; signals overvoltage fault to host controller |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent comparators | Enables simultaneous undervoltage and overvoltage window detection without external components or timing coordination |
| 0.5% factory-trimmed hysteresis | Eliminates need for external hysteresis resistors and reduces PCB area in space-constrained telecom modules |
| 72V-rated open-drain outputs | Directly interfaces with 48V rail monitoring without level-shifting, simplifying fault signaling in distributed power architectures |
| BiCMOS process with -40°C to +125°C rating | Ensures stable comparator offset and propagation delay across extended industrial temperature range |
| Complementary enable inputs (EN/EN) | Supports both active-high and active-low system control signals, easing integration into legacy and new MCU GPIO designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar overvoltage/undervoltage window detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16011TAA+T | Single active-high EN input and LOGIC-selectable OUTB polarity; identical threshold accuracy and hysteresis | Preferred where system GPIO only supports active-high enables and configurable fault polarity is required | Select MAX16011TAA+T when OUTB logic inversion (via LOGIC pin) is needed without redesigning enable signal routing |
| TLV809E33DBVR | Single-channel 3.3V reset IC with 200ms timeout; no dual-threshold capability; 1.8V–6V supply only | Limited to single-supply undervoltage reset; unsuitable for 48V window detection or overvoltage response | Use TLV809E33DBVR only for low-voltage microcontroller reset in auxiliary subsystems-not as functional replacement for MAX16010TAA+T |
Compared with MAX16011TAA+T, the MAX16010TAA+T offers complementary enable control ideal for fail-safe systems requiring both active-high and active-low assertion; compared with TLV809E33DBVR, it delivers full 5.5V–72V window detection with sub-µs timing-making it irreplaceable in high-voltage telecom and battery-stack applications.

FAQ
What is the exact function of MAX16010TAA+T in a 48V telecom power system?
The MAX16010TAA+T functions as a dual-threshold voltage supervisor in 48V telecom systems, using INA+ and INB- to independently detect undervoltage (e.g., <42V) and overvoltage (e.g., >57V) conditions. Its OUTA and OUTB open-drain outputs assert faults within 2µs to disable downstream converters or trigger system-level shutdown, meeting Telcordia GR-1089 surge immunity requirements without external components.
Does MAX16010TAA+T support adjustable overvoltage thresholds?
Yes, MAX16010TAA+T supports fully adjustable overvoltage thresholds via external resistor dividers on INB-. With its 1.245V internal reference and 0.5% hysteresis, users can set precise trip points-for example, configuring a 56V overvoltage threshold using R1=1.02MΩ, R2=100kΩ, and R3=10kΩ-enabling customization across diverse 48V, 60V, and battery-stack applications.
How does the complementary EN/EN enable scheme improve system reliability in MAX16010TAA+T?
The complementary EN/EN inputs in MAX16010TAA+T allow independent assertion of active-high and active-low control signals, enabling hardware-enforced fail-safe behavior. For instance, tying EN to a watchdog timer output and EN to a manual reset line ensures that either signal alone can force both outputs low-preventing spurious enablement during power-up sequencing or brown-out recovery in mission-critical telecom equipment.
What is the maximum sink current capability of MAX16010TAA+T's OUTA and OUTB outputs?
MAX16010TAA+T's OUTA and OUTB outputs each support up to 3.2mA sink current at VCC ≥5.5V while maintaining VOL ≤0.4V. This allows direct interface with standard 4.7kΩ pullup resistors to 48V rails or microcontroller GPIOs, eliminating level shifters in high-side fault signaling paths-critical for minimizing latency in overvoltage response loops.
Can MAX16010TAA+T operate reliably at 72V supply with full specification compliance?
Yes, MAX16010TAA+T is fully specified from 5.5V to 72V supply voltage across –40°C to +125°C. Electrical characteristics-including propagation delay (2µs max), threshold accuracy (±3mV), and supply current (≤40µA)-are guaranteed at 72V per Analog Devices' datasheet Rev 6 (Oct 2024), making it suitable for peak-line applications such as industrial 60V DC distribution and EV auxiliary battery monitoring.
