Product details
Overview
MAX16012TT+T from Analog Devices is a single-channel overvoltage detection IC with integrated 1.30V reference output, designed for high-voltage industrial and telecom power-rail monitoring. It operates from 5.5V to 72V supply, features open-drain comparator output (OUT), 2µs max propagation delay, and supports active-high or active-low logic configuration via REF-to-IN+/- connection. It is used in 48V server power sequencing and multicell battery-stack supervision.
For engineers reviewing the MAX16012TT+T datasheet, MAX16012TT+T pinout, MAX16012TT+T application, or MAX16012TT+T equivalent, this page delivers verified electrical parameters, validated 6-pin TDFN-EP package mapping, confirmed comparator reference behavior, and real-world design implications for overvoltage threshold setting and logic polarity selection.
Technical Context
The MAX16012TT+T integrates a precision comparator with independently accessible IN+ and IN− inputs and a stable 1.30V internal reference (REF) capable of sourcing/sinking up to 1µA. Its output (OUT) is open-drain, rated for up to 72V, and asserts low when IN+ < IN− or high when IN+ > IN− - logic polarity selected by connecting REF to either input.
It includes internal undervoltage lockout (UVLO) triggering at 4.75V–5.25V, consumes only 20–40µA across 12V–48V VCC, and maintains ±12.5mV input offset voltage over −40°C to +125°C. The device lacks enable control or MOSFET drive circuitry - distinguishing it from MAX16013/MAX16014 - and is strictly a detection-only solution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5V to 72V - supports direct connection to 48V telecom rails, 60V battery stacks, and industrial 24/48V systems without external regulators. |
| Reference Output Voltage | 1.275V to 1.320V (typ 1.30V) - enables precise resistor-divider-based threshold setting with <±3mV variation; stable under 0–50pF capacitive load. |
| Propagation Delay | 2µs (max) - ensures fast response to transient overvoltage events, critical for protecting downstream DC-DC converters and FPGAs. |
| Input Offset Voltage | ±12.5mV - limits threshold-setting error to <1% at 1.3V reference; directly impacts accuracy of 10%–20% overvoltage trip points. |
| Supply Current | 20µA (VCC = 12V), 40µA (VCC = 48V) - ultra-low quiescent draw enables always-on monitoring in battery-backed systems. |
| Operating Temperature | −40°C to +125°C - fully specified for under-hood automotive-adjacent industrial enclosures and telecom base station environments. |
| Output Type | Open-drain OUT pin - requires external pull-up to VCC or system rail; supports level-shifting and wired-OR fault signaling across mixed-voltage domains. |
Pinout & Package
MAX16012TT+T is housed in a 3mm × 3mm, 6-pin TDFN-EP package with exposed pad (EP) connected to GND for thermal and EMI performance. Pin 1 is VCC; pin 2 is GND; pin 3 is OUT; pin 4 is IN−; pin 5 is REF; pin 6 is IN+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply input | Accepts 5.5V–72V; must be bypassed with ≥0.1µF capacitor to GND; UVLO activates below 4.75V. |
| GND (Pin 2) | Ground reference | Common return for all analog and digital functions; EP pad must be soldered to PCB ground plane. |
| OUT (Pin 3) | Open-drain comparator output | Drives low when IN+ < IN−; requires external pull-up; sinks up to 3.2mA at 0.4V VOL. |
| IN− (Pin 4) | Inverting comparator input | Connected to REF for active-high output; accepts 0–4V common-mode range; input current <±100nA. |
| REF (Pin 5) | 1.30V internal reference output | Sources/sinks ≤1µA; connects to IN+ or IN− to set output logic polarity; stable with 0–50pF load. |
| IN+ (Pin 6) | Noninverting comparator input | Connected to REF for active-low output; common-mode range 0–4V; offset voltage ±12.5mV. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1.30V reference | Enables self-contained threshold generation without external voltage references or precision resistors. |
| Configurable output logic | Active-high or active-low output achieved by routing REF to IN− or IN+, eliminating need for external inverters. |
| Ultra-low supply current | 20–40µA operation allows permanent monitoring in energy-constrained battery-stack applications. |
| High-voltage open-drain output | OUT rated to 72V supports direct interfacing with 48V system rails and simplifies fault-signaling architecture. |
| Fast 2µs propagation delay | Ensures sub-microsecond response to overvoltage transients, meeting IEC 61000-4-4 surge immunity timing requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar overvoltage detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3012IDBVR | Single comparator with 1.24V reference; 1.8V–5.5V supply only; no 72V-rated output. | Limited to low-voltage systems (<6V); unsuitable for 48V telecom or battery-stack use. | Select only for sub-6V applications where MAX16012TT+T's high-voltage capability is unnecessary. |
| MAX6440UTLTD3+T | Fixed 3.08V threshold, no adjustable reference; 1.6V–5.5V supply; open-drain output. | Designed for microprocessor reset supervision, not high-voltage rail monitoring. | Use only when fixed-threshold, low-voltage reset signaling is required - not for scalable overvoltage detection. |
Compared with TLV3012IDBVR and MAX6440UTLTD3+T, the MAX16012TT+T uniquely combines 72V supply tolerance, 1.30V programmable reference, and 2µs response - making it the sole option among the three for direct 48V rail monitoring without level-shifting or external biasing.

FAQ
What is the exact reference voltage tolerance of the MAX16012TT+T?
The MAX16012TT+T delivers a reference output voltage of 1.275V to 1.320V (min to max) across −40°C to +125°C, with typical value 1.30V. This ±1.5% tolerance enables accurate resistor-divider-based threshold setting for overvoltage detection without trimming. The MAX16012TT+T reference remains stable under capacitive loads up to 50pF and sources/sinks up to 1µA.
How do I configure the MAX16012TT+T for active-high versus active-low output logic?
To configure active-high output on the MAX16012TT+T, connect the REF pin to the IN− pin; then apply the monitored voltage to IN+. When IN+ exceeds REF, OUT goes high. For active-low output, connect REF to IN+, and apply the monitored voltage to IN−; OUT goes low when IN− exceeds REF. This logic polarity selection is internal to the MAX16012TT+T and requires no external components.
Does the MAX16012TT+T include an enable input or power-down mode?
No, the MAX16012TT+T does not include an enable input or hardware power-down mode. It operates continuously whenever VCC is within 5.5V–72V. Unlike MAX16010/MAX16011 (which feature EN/EN) or MAX16013/MAX16014 (with EN), the MAX16012TT+T is a dedicated comparator with no enable functionality - its supply current remains constant at 20–40µA across operating conditions.
What is the maximum voltage the OUT pin of the MAX16012TT+T can tolerate?
The OUT pin of the MAX16012TT+T is rated for voltages up to 72V, matching the device's VCC absolute maximum rating. As an open-drain output, it safely interfaces with higher-voltage rails (e.g., 48V or 60V) when pulled up externally. Leakage current remains ≤500nA at 72V, ensuring minimal false-trigger risk in high-noise environments.
Can the MAX16012TT+T drive a p-channel MOSFET gate directly?
No, the MAX16012TT+T cannot drive a p-channel MOSFET gate directly. It lacks gate-driver circuitry - unlike MAX16013/MAX16014 which provide GATE1/GATE2 outputs. The MAX16012TT+T only provides an open-drain comparator output (OUT). To control a MOSFET, the OUT signal must be buffered or level-shifted using external discrete components or a dedicated driver IC.
