MAX14743

Over Voltage and Surge Protected Dual SPDT Data Line Switch

Protect the data line from a high-voltage short or surge event


Please check latest availability status for a specific part variant.

Description

The MAX14743/MAX14743A are 2 x SPDT switches with overvoltage protection intended for use with portable devices. As the high-voltage charging solution starts to spread out, a data line short event to the high-voltage VBUS can result in either charger misdetection or permanent damage to the portable device. The MAX14743/MAX14743A are designed to protect the downstream data line from a high-voltage short or surge event.

The device combines low on-capacitance (CON) and low on-resistance (RON) necessary for high-performance switching applications in portable electronics.The MAX14743/MAX14743A feature internal positive overvoltage, negative overvoltage, and surge protection. The devices handle USB low/full/high-speed signaling and operate from a 2.7V to 5.5V supply.

The MAX14743/MAX14743A are available in a 12-bump (1.22mm x 1.62mm) wafer-level package (WLP) and operates over the -40°C to +85°C extended temperature range.
