Product Details

The MAX20330 is an overvoltage controller with the VBUS impedance detection function. The device drives an external low RON path for the device that requires a flexible and adjustable OVLO threshold. The VBUS impedance detection can detect the soft short on VBUS and warn the user about the potential connector overheating.

The MAX20330 is designed to drive a single or dual back-to-back external N-channel MOSFET with a low RON (10mΩ max). An external TVS can be used to protect the device from a high energy surge if necessary.

The device is available in an 8-bump (0.35mm pitch, 1.77mm x 1.03mm) wafer-level package (WLP) and operate over the -40ºC to +85°C extended temperature range.
