MAX20334

OverVoltage 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 MAX20334 is a 2 x SPDT switch with overvoltage protection intended for use with portable devices. In highvoltage charging solutions, a data line short event to the high-voltage VBUS can result in either charger misdetection or permanent damage to the portable device. The MAX20334 is 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 MAX20334 features internal positive overvoltage, negative overvoltage, and surge protection. The device handles USB low/full/high-speed signaling and operates from a 2.7V to 5.5V supply.

The MAX20334 is available in a 12-bump (1.23mm x 1.63mm) wafer-level package (WLP) and operates over the -40°C to +85°C extended temperature range.
