Product Description & Specifications

iProTxTM (pronounced “i-pro-tex”), is an ESD (Electrostatic Discharge) and Current-Limiting protection module for I2C Bus and SMBus circuit protection in testing and manufacturing environments.

It is estimated that up to a third of all electronic products are damaged by ESD. This is especially discouraging when you consider that a significant percentage of this damage can occur in test fixtures on a production line.

iProTx brings ESD and current-limiting protection to devices connected to an I2C or SMBus. Based on transient voltage suppression (TVS) technology created for hot-plug USB devices, and automatic resetting fuses for over-current protection, the iProTx gives I2C or SMBus devices protection in automatic insertion applications typically found in factory automation, testing, and plug-and-play environments.

PRODUCT HIGHLIGHTS

* Protects I2C and SMBus devices in Lab or Factory Environments.
* Inserts In-Line between I2C Systems.
* Protection for SCL, SDA, Interrupt, Power, and Ground.
* 5 Volt Tolerant.
* Transient Voltage Suppression and Auto-Resetting Fuses.
* Compatible with bus speeds up to 400 kHz.
* Plug-Compatible with MCC I2C Products and Connectors.

iProTx provides I2C and SMBus devices with up to 15 kV of ESD protection, and current-limiting protection of 400 mA for signals and 1 A for power. Supporting bus speeds up to 400 kHz, the iProTx generates only 40 pF of bus loading capacitance.
