Introduction

The MAX20330 is an overvoltage controller with the VBUS impedance detection function. The device drives an external low R_ON 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 R_ON (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 0.35 mm pitch, 1.77 mm × 1.03 mm wafer-level package (WLP) and operate over the -40 ℃ to +85 ℃ extended temperature range. The MAX20330 features the overvoltage protection to the charger input VBUS line when a travel adapter (TA) is used. The MAX20330 uses the external N-MOSFET with R_ON lower than 10 mΩ and V_DS rating at or higher than +30 V. The device protects the battery and low voltage sys
