Product details
Overview
MAX16010TAC+ from Analog Devices is an ultra-small, low-power overvoltage/undervoltage protection IC with dual independent comparators, 5.5V–72V supply range, 7.5% threshold hysteresis, open-drain outputs rated to 72V, and fast 2µs propagation delay. It serves as a window voltage monitor in telecom power supplies and industrial battery-stack systems.
For engineers reviewing the MAX16010TAC+ datasheet, MAX16010TAC+ pinout, MAX16010TAC+ application, or MAX16010TAC+ equivalent, this page delivers verified circuit role, exact pin functions, real-world timing behavior, thermal performance across -40°C to +125°C, and validated alternatives for high-voltage transient protection design.
Technical Context
The MAX16010TAC+ implements two independent rail-to-rail input comparators with internal 1.245V threshold reference and user-adjustable hysteresis (7.5% for TAC variant). Its complementary enable inputs (EN/EN) provide robust control logic for fault-safe activation and forced output disable.
It features integrated undervoltage lockout (UVLO) at 4.75V–5.25V, supports direct connection of external resistor dividers to INA+ and INB- for precise trip-point setting, and maintains stable operation under high dv/dt transients common in 48V telecom and multicell battery systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5V to 72V - enables direct use in 48V telecom, server PSUs, and 12–60-cell Li-ion stacks without external regulators. |
| Threshold Voltage (VTH+) | 1.215V to 1.265V - sets precise overvoltage/undervoltage trip points via external resistive divider on INA+/INB-. |
| Hysteresis | 7.5% - prevents chatter during noisy voltage transitions near threshold; confirmed for MAX16010TAC variant per datasheet Table. |
| Propagation Delay | 2µs max - ensures rapid response to overvoltage faults, critical for protecting downstream DC-DC converters and FPGAs. |
| Operating Temperature | -40°C to +125°C - fully specified for industrial and telecom equipment operating in uncontrolled ambient environments. |
| Input Supply Current | 20–40µA - ultra-low quiescent current preserves battery life in always-on monitoring applications. |
| UVLO Threshold | 4.75V to 5.25V - disables outputs below safe operating voltage, preventing erratic comparator behavior during brownout. |
Pinout & Package
MAX16010TAC+ uses an 8-pin 3mm × 3mm TDFN-EP package with exposed pad (EP) connected to GND for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INA+ | Noninverting Input A | Undervoltage monitor input; OUTA asserts low when INA+ drops below VTH− (1.12–1.18V for TAC). |
| 2 OUTA | Open-Drain Output A | Active-low undervoltage flag; requires external pullup to VCC; sinks up to 3.2mA at 0.4V VOL. |
| 3 EN | Active-Low Enable | Forces both outputs low when high; internally pulled up to VCC; tie to GND if unused. |
| 4 INB- | Inverting Input B | Overvoltage monitor input; OUTB asserts low when INB- exceeds VTH+ (1.215–1.265V). |
| 5 VCC | Positive Supply Input | 5.5V–72V main power rail; absolute max 80V; bypass with ≥0.1µF capacitor to GND. |
| 6 GND | Ground Reference | System ground return; EP must be soldered to GND plane for thermal stability and noise immunity. |
| 7 EN | Active-High Enable | Complementary to Pin 3; drives outputs active when high; internally pulled down to GND. |
| 8 OUTB | Open-Drain Output B | Active-low overvoltage flag; same drive capability as OUTA; logic polarity fixed (no LOGIC pin). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitors | Simultaneous undervoltage (INA+) and overvoltage (INB-) detection with separate open-drain outputs for fault isolation. |
| 7.5% hysteresis (TAC variant) | Guaranteed noise margin against false triggering in high-dv/dt telecom bus environments; eliminates need for external RC filtering. |
| Ultra-low supply current | 20–40µA across full 5.5–72V range - enables multi-year operation on backup batteries in remote industrial sensors. |
| Wide temperature specification | Full electrical performance guaranteed from -40°C to +125°C - suitable for under-hood automotive auxiliary modules and outdoor telecom cabinets. |
| Robust 72V output rating | OUTA/OUTB tolerate up to 72V - allows direct interface with 48V system rails without level-shifting or clamping diodes. |
Applications
| Telecom Power Supervision | Industrial Battery Stack Monitoring |
|---|---|
|

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+ | Shares identical threshold, hysteresis, and timing specs but uses single active-high EN and selectable LOGIC pin for OUTB polarity inversion. | Lacks complementary EN/EN inputs; requires additional logic for safety-critical enable/disable sequences where dual-edge control is mandated. | Select MAX16011TAC+ only when system-level fault handling relies on configurable output polarity and simplified enable architecture. |
| TLV809E33DBZR | Single-channel 3.3V supervisor with 200ms reset timeout; no adjustable threshold, no hysteresis option, 6V max VCC. | Cannot replace dual-window function; limited to low-voltage microcontroller reset generation, not high-voltage rail supervision. | Use TLV809E33DBZR only for cost-sensitive, single-rail 3.3V systems where adjustable thresholds and fast response are unnecessary. |
Compared with MAX16011TAC+, MAX16010TAC+ provides deterministic dual-edge enable control essential for IEC 61508 functional safety architectures; compared with TLV809E33DBZR, it delivers scalable high-voltage supervision with precision hysteresis-neither offers drop-in replacement capability due to fundamental differences in channel count, voltage range, and configurability.

FAQ
What is the exact hysteresis value for MAX16010TAC+?
The MAX16010TAC+ has a guaranteed 7.5% threshold hysteresis, meaning VTH− is 7.5% lower than VTH+ (e.g., 1.245V nominal VTH+ yields ~1.15V VTH−). This value is explicitly assigned to the "C" suffix in the ordering code and confirmed in the Electrical Characteristics table of the MAX16010–MAX16014 datasheet Rev 6.
Can MAX16010TAC+ drive MOSFET gates directly?
No, MAX16010TAC+ does not include gate-driver outputs. It is a pure voltage-monitoring IC with open-drain comparator outputs (OUTA/OUTB). For MOSFET control, use MAX16013TTC+ or MAX16014TTC+, which integrate dedicated GATE1/GATE2 drivers. MAX16010TAC+ requires external logic or driver stages to interface with power FETs.
What is the maximum input voltage the INA+ and INB- pins can tolerate?
INA+ and INB- pins are rated for -0.3V to +12V per Absolute Maximum Ratings. They must be biased within this range using external resistor dividers when monitoring voltages above 12V - for example, a 10:1 divider reduces a 72V rail to 7.2V at the input pin, staying safely within spec.
Does MAX16010TAC+ include undervoltage lockout (UVLO)?
Yes, MAX16010TAC+ includes internal UVLO that disables both outputs when VCC falls below 4.75V (min) and re-enables them when VCC rises above 5.25V (max). This behavior is documented in Table 1 (UVLO State) and ensures clean startup and shutdown sequencing in battery-powered systems.
Is the exposed pad (EP) of MAX16010TAC+ required to be connected to GND?
Yes, the exposed pad (EP) must be soldered to a GND plane. It serves as the primary thermal path and contributes to EMI suppression. Leaving EP floating degrades thermal resistance by >50% and increases susceptibility to noise-induced false triggering, violating the recommended layout in the MAX16010–MAX16014 package documentation.
