Analog Devices Inc./Maxim Integrated MAX13047EEVB+T

Overview

The MAX13047EEVB+T from Maxim Integrated is a dual-channel, bidirectional, ±15kV ESD-protected level translator IC designed for voltage-level shifting between low-voltage (VL = +1.1V to +3.6V) and higher-voltage (VCC = +1.65V to +5.5V) domains in multivoltage systems. It supports guaranteed 8Mbps push-pull data rates, features shutdown mode with <1μA supply current, and uses transmission-gate architecture for true bidirectional translation on each channel. It is commonly used in I²C and 1-Wire interface bridging between low-power ASICs/PLDs and 3.3V/5V peripherals.

For engineers reviewing the MAX13047EEVB+T datasheet, MAX13047EEVB+T pinout, MAX13047EEVB+T application, or MAX13047EEVB+T equivalent, key selection considerations include its dual-channel UTQFN-10 package, VL/VCC supply flexibility, ±15kV HBM ESD rating on VCC-side I/Os, thermal short-circuit protection, and compatibility with rail-to-rail or open-drain driving topologies.

Technical Context

The MAX13047EEVB+T implements a transmission-gate-based bidirectional level-shifting architecture with integrated rise-time accelerators on both VL and VCC sides, enabling up to 16Mbps operation under +1.8V ≤ VL ≤ VCC ≤ +3.3V conditions. Its internal 10kΩ pullup resistors on I/O VL and I/O VCC lines support open-drain configurations without external components.

Shutdown is controlled via the SHDN pin, which disconnects internal pullups and forces I/Os into high-impedance state while limiting total supply current to <1μA. The device incorporates thermal-overload detection that triggers automatic shutdown at TJ > +150°C and resumes operation below +140°C.

Key Specifications

Pinout & Package

The MAX13047EEVB+T is housed in a 10-pin UTQFN package (1.4mm × 1.8mm, 0.5mm pitch) with wettable flanks for automated optical inspection. Thermal resistance θJA = 20.1°C/W enables reliable operation at full speed without heatsinking in compact layouts.

FAQ

What is the minimum VL supply voltage supported by the MAX13047EEVB+T?

The MAX13047EEVB+T supports VL as low as +1.1V, enabling direct interfacing with advanced low-power logic families such as 1.2V and 1.1V ASICs and PLDs. This specification is guaranteed over the full –40°C to +85°C operating temperature range and is validated in the Electrical Characteristics table under "VL Supply Range" with MIN = 1.1V.

Does the MAX13047EEVB+T require external pullup resistors for I²C operation?

No - the MAX13047EEVB+T integrates 10kΩ pullup resistors on both I/O VL and I/O VCC lines, eliminating the need for external pullups in standard open-drain I²C configurations. These internal resistors are automatically disconnected during shutdown mode to maintain high-impedance I/O states.

Can the MAX13047EEVB+T operate with VCC disconnected while VL remains powered?

Yes - the MAX13047EEVB+T enters shutdown mode when VCC is disconnected or grounded while VL is active. In this state, I/O VL remains functional and undamaged, though translation to I/O VCC is disabled. This feature enables selective power gating in battery-operated systems without risking device damage.

What ESD protection standards does the MAX13047EEVB+T meet on its VCC-side I/Os?

The MAX13047EEVB+T provides ±15kV Human Body Model (HBM), ±15kV IEC61000-4-2 air-gap discharge, and ±8kV IEC61000-4-2 contact discharge protection on I/O VCC pins. This exceeds Level 4 IEC61000-4-2 system-level immunity requirements and removes the need for external ESD suppression components in most end-equipment designs.

How does the MAX13047EEVB+T handle thermal overload conditions?

The MAX13047EEVB+T incorporates thermal-overload detection that triggers automatic shutdown when junction temperature exceeds +150°C. Once cooled below +140°C, the device autonomously resumes normal operation - providing self-protecting behavior during sustained I/O short-circuit events without requiring external monitoring circuitry.
