Product details
Overview
MAX16010TAC+T from Analog Devices is an ultra-small, low-power overvoltage/undervoltage window detector IC for high-voltage systems. It features two independent comparators (INA+, INB-) with open-drain outputs (OUTA, OUTB) rated to 72V, 7.5% hysteresis, 2µs max propagation delay, and operates from 5.5V to 72V supply across –40°C to +125°C - used in telecom power supervision and multicell battery-stack protection.
For engineers reviewing the MAX16010TAC+T datasheet, MAX16010TAC+T pinout, MAX16010TAC+T application, or MAX16010TAC+T equivalent, this page delivers verified circuit role, exact hysteresis value, dual-threshold behavior, UVLO threshold (5.0V), and functional distinction from MAX16011/MAX16014 variants - critical for 48V server rail monitoring and reverse-battery-protected industrial modules.
Technical Context
The MAX16010TAC+T implements a dual-comparator window detection architecture with fixed internal reference (1.245V typ) and user-adjustable thresholds via external resistor dividers on INA+ and INB-. Its complementary enable inputs (EN/EN) provide fail-safe control: EN low or EN high forces both outputs low, while simultaneous EN=high and EN=low enables normal window monitoring.
It integrates internal undervoltage lockout (VUVLO = 5.0V) and supports fast transient response (2µs propagation delay) with open-drain outputs capable of sinking 3.2mA at 0.4V VOL. The 7.5% hysteresis (TAC suffix) is factory-trimmed and applies to both thresholds, ensuring noise immunity in high-dV/dt telecom and industrial bus environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5V to 72V - powers directly from 48V telecom or 60V battery stacks without external regulators. |
| Threshold Voltage (VTH+) | 1.245V (typ) - sets upper trip point when referenced via resistive divider; enables precise 28V overvoltage detection at VCC=48V. |
| Hysteresis | 7.5% - fixed factory-trimmed hysteresis (TAC suffix) prevents chatter during slow-rising/falling input transients. |
| Propagation Delay | 2µs (max) - ensures rapid fault response for protecting downstream DC-DC converters and FPGAs. |
| UVLO Threshold | 5.0V (typ) - disables outputs below safe operating voltage, preventing erratic behavior during brownout. |
| Output Type | Open-drain (OUTA/OUTB) - allows level-shifting up to 72V and wired-OR configuration with other supervisors. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood industrial and telecom equipment with no derating. |
Pinout & Package
MAX16010TAC+T uses an 8-pin 3mm × 3mm TDFN-EP package 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; OUTA asserts low when INA+ drops below VTH− (1.15V typ for TAC). |
| OUTA | Open-drain undervoltage output | Sinks current when undervoltage condition occurs; requires external pullup to VCC or system rail. |
| EN | Active-low enable input | Internally pulled up to VCC; drives OUTA/OUTB low when asserted - used for system-level disable. |
| INB- | Inverting input for overvoltage comparator | Monitors rising voltage; OUTB asserts low when INB- exceeds VTH+ (1.245V typ). |
| VCC | Positive supply input | Accepts 5.5V–72V; includes internal UVLO and bypass capacitor recommendation (≥0.1µF). |
| GND | Ground reference | Return path for all analog and digital functions; EP must be soldered to GND plane. |
| EN | Active-high enable input | Internally pulled down to GND; complements EN for robust enable logic - both must be controlled. |
| OUTB | Open-drain overvoltage output | Asserts low during overvoltage; shares same timing and drive strength as OUTA (2µs, 3.2mA sink). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent comparators | Enables true window detection with separate UV/OV thresholds - eliminates need for external op-amps or logic. |
| 7.5% factory-trimmed hysteresis | Guarantees stable switching without external RC networks - critical for noisy 48V telecom backplanes. |
| Complementary enable inputs (EN/EN) | Supports redundant enable schemes and failsafe shutdown - both pins must be valid for normal operation. |
| 72V-tolerant open-drain outputs | Directly interfaces with 48V or 60V system rails without level shifters - reduces BOM count and layout area. |
| Ultra-low quiescent current (30µA typ) | Minimizes standby power in always-on battery-stack monitors - extends runtime in remote sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar overvoltage/undervoltage detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16011TAC+T | Single active-high EN input; LOGIC pin selects OUTB polarity; identical thresholds/hysteresis. | Lacks complementary enable - less suitable for safety-critical dual-redundant enable paths. | Select MAX16011TAC+T only if system uses single-enable logic and requires configurable OUTB polarity. |
| TLV809EC26DBVR | Single-channel 2.63V reset IC; no window detection; 3.6V max VCC; SOT-23-3 package. | Cannot monitor both UV and OV simultaneously; limited to low-voltage microcontroller reset. | Use TLV809EC26DBVR only for simple MCU reset in sub-5V domains - not a functional substitute for MAX16010TAC+T. |
Compared with MAX16011TAC+T, the MAX16010TAC+T provides superior fault containment via dual-enable logic; compared with TLV809EC26DBVR, it delivers full window supervision at high voltage with integrated hysteresis - essential for telecom and industrial power integrity.

FAQ
What is the exact hysteresis value for MAX16010TAC+T?
The MAX16010TAC+T has a factory-trimmed 7.5% hysteresis, confirmed by the "C" suffix in its part number per Maxim/Analog Devices ordering nomenclature. This applies to both INA+ and INB- thresholds, yielding VTH+ = 1.245V (typ) and VTH− = 1.15V (typ) at 25°C. Hysteresis remains stable across –40°C to +125°C per datasheet Figure 5.
How does the complementary enable logic (EN/EN) function in MAX16010TAC+T?
In MAX16010TAC+T, EN is active-low and internally pulled up to VCC, while EN is active-high and internally pulled down to GND. Driving either EN low or EN high forces both OUTA and OUTB low. Normal window detection requires EN = high AND EN = low simultaneously - providing hardware-enforced dual-input safety for critical power systems.
Can MAX16010TAC+T monitor voltages above 72V?
No. MAX16010TAC+T has an absolute maximum VCC rating of 80V and specified operation only from 5.5V to 72V. Inputs INA+, INB-, and outputs OUTA/OUTB tolerate up to 72V, but exceeding 72V violates operational specifications and risks permanent damage. For >72V systems, external voltage scaling or dedicated high-voltage supervisors are required.
What is the purpose of the exposed pad (EP) on MAX16010TAC+T?
The exposed pad (EP) on MAX16010TAC+T must be soldered to a GND plane to ensure proper thermal dissipation and EMI suppression. It is electrically connected to GND internally and improves thermal resistance by ~30°C/W versus non-EP variants. Failure to connect EP to GND may cause overheating or false fault triggering in high-ambient industrial environments.
Does MAX16010TAC+T include an internal voltage reference?
Yes. MAX16010TAC+T contains an internal 1.245V (typ) precision reference used for both INA+ and INB- comparators. This reference is trimmed and temperature-compensated, enabling accurate threshold setting without external references. Its stability is guaranteed across –40°C to +125°C per Electrical Characteristics table (VTH+ min/max).
