Analog Devices / Maxim Integrated MAX20330 Programmable OVP Control PMIC

Analog Devices MAX20330 Programmable Overvoltage (OVP) Control Power Management IC (PMIC) is a controller with the V_BUS impedance detection function. The V_BUS impedance detection can detect the soft short and warn the user about the potential connector overheating. The MAX20330 PMIC drives an external low R_ON path for the device that requires a flexible and adjustable OVLO threshold. This overvoltage controller is designed with a built-in charge pump to drive a single or dual back-to-back external N-channel MOSFET with a low R_ON (10mΩ max). The MAX20330 OVP controller features 100ns ultra-fast turn-off time and thermal shutdown protection.

The Analog Devices MAX20330 Programmable Overvoltage PMIC input voltage ranges from 2.7V to 36V and operates within -40ºC to 85°C extended temperature range. This PMIC is available in an 8-bump (0.35mm pitch, 1.77mm x 1.03mm) Wafer-Level Package (WLP) and is ideal for smartphones, tablets, phablets, and desktops.
