Overview

Description

Introduction to MAX3491ESD
- The MAX3491ESD is a Maxim/Analog Devices multi-channel ESD protection diode array designed to guard high‑speed data lines from electrostatic discharge and transients.
- It provides multiple protection channels (e.g., 4 channels) with ultra-low input capacitance to minimize signal distortion on interfaces like USB, HDMI, MIPI (CSI/DSI), LVDS, CAN, etc.
- Each channel clamps surges to the system rails (Vcc and GND), diverting ESD away from protected ICs.
- Benefits: enhances device reliability, reduces ESD‑induced errors, small footprint, low leakage, and suitable for wide operating temperatures.
- How to use: place the device close to the protected connector; connect to the host’s Vcc and GND rails; protect target data lines through the channels.
- Notes: refer to the datasheet for exact channel count, working voltage, per-channel capacitance, ESD ratings (HBM/CDM), package options, and layout guidelines.

Package

The MAX3491ESD is packaged in a 20-pin package, typically TSSOP-20 (SO-20 variants also appear in listings). Check the datasheet for exact package options.

Pinout

- Pin count: 8 pins (MSOP-8/SOIC-8)
- Function: ESD protection diode array for multiple I/O lines (typically four bidirectional data lines); clamps ESD/transient events to Vcc and GND to protect downstream circuitry. No active signaling or logic.

Manufacturer

MAX3491ESD is manufactured by Maxim Integrated, a fabless semiconductor company that designs and markets analog and mixed-signal integrated circuits. Maxim is now a subsidiary of Analog Devices, Inc.

Application

Applications: ESD protection for high-speed differential data lines (LVDS, RS-422/485) in consumer, industrial, and automotive electronics; protects connectors, backplanes, displays, cameras, printers, and networking equipment.
