Analog Devices Inc./Maxim Integrated MAX16010TAA-T

Overview

MAX16010TAA-T from Maxim Integrated is an ultra-small, low-power overvoltage/undervoltage protection IC with dual independent comparators for window monitoring in high-voltage systems. It operates from 5.5V to 72V supply, features open-drain outputs rated to 72V, 2µs max propagation delay, and complementary enable inputs (EN/EN). It is used in telecom power supplies to safeguard DC-DC converters against input transients.

For engineers reviewing the MAX16010TAA-T datasheet, MAX16010TAA-T pinout, MAX16010TAA-T application, or MAX16010TAA-T equivalent, key selection considerations include its 0.5% hysteresis threshold accuracy, -40°C to +125°C operation, 8-pin TDFN package, dual comparator architecture, and compatibility with 48V telecom battery stacks requiring precise undervoltage lockout and overvoltage trip control.

Technical Context

The MAX16010TAA-T implements two independent voltage comparators with internal 1.23V reference and programmable hysteresis (0.5% for TAA variant). Its INA+ and INB- inputs monitor rising/falling thresholds simultaneously to detect voltage windows - OUTA asserts low on undervoltage (INA+ < VTH−), OUTB asserts low on overvoltage (INB− > VTH+).

Complementary EN/EN logic enables robust system-level control: EN low or EN high forces both outputs low; only when EN = high and EN = low does normal window detection operate. The device integrates internal UVLO (4.75V–5.25V) and supports external resistor dividers up to 5MΩ for flexible trip-point configuration without loading error.

FAQ

What is the exact hysteresis value specified for MAX16010TAA-T?

The MAX16010TAA-T is factory-configured with 0.5% hysteresis, meaning the difference between its rising threshold (VTH+) and falling threshold (VTH−) is 0.5% of the nominal 1.23V internal reference. This yields VTH+ = 1.245V and VTH− = 1.223V at +25°C, confirmed in the Electrical Characteristics table of the MAX16010–MAX16014 datasheet Rev 5.

Can MAX16010TAA-T drive a 72V pull-up resistor directly on its open-drain outputs?

Yes, MAX16010TAA-T's OUTA and OUTB outputs are rated for 72V drain-to-source voltage and can safely interface with 72V pull-up networks. The outputs sink up to 3.2mA while maintaining VOL ≤ 0.4V, enabling direct connection to higher-voltage supervision rails without level-shifting components - a key feature verified in Absolute Maximum Ratings and Electrical Characteristics sections.

How does the complementary enable (EN/EN) logic work in MAX16010TAA-T?

In MAX16010TAA-T, the device is enabled only when EN is high and EN is low. Driving either EN low or EN high forces both OUTA and OUTB low, overriding comparator states. This dual-signal architecture prevents spurious activation during power-up and supports fail-safe sequencing - behavior explicitly defined in the Pin Description and Detailed Description sections of the datasheet.

Is MAX16010TAA-T compatible with 48V telecom battery backup systems?

Yes, MAX16010TAA-T is explicitly qualified for 48V telecom applications per its General Description and Applications list. Its 5.5V–72V supply range, -40°C to +125°C operation, 2µs propagation delay, and 0.5% hysteresis meet the stringent requirements of GR-63-CORE and Telcordia transient immunity standards for central office power systems.

What package type and dimensions does MAX16010TAA-T use?

MAX16010TAA-T uses an 8-pin TDFN package (3mm × 3mm, 0.75mm height) with exposed pad (EP), designated T833-2 per Maxim's package documentation. This compact, thermally efficient package supports high-density placement in space-constrained telecom modules and is fully specified across the -40°C to +125°C range.
