MAX20330 Programmable OVP Controller with VBUS Short Detection General Description Benefits and Features The MAX20330 is an overvoltage controller with the VBUS Protects High-Power Portable Devices impedance detection function. The device drives an exter- Wide Operating Input Voltage Protection Range: nal low R path for the device that requires a flexible 2.7V to 36V ON Ultra-Fast Turn-Off Time: 100nsec and adjustable OVLO threshold. The VBUS impedance detection can detect the soft short on VBUS and warn the Built-In Charge Pump to Drive External N-MOSFET user about the potential connector overheating. Flexible Overvoltage Protection Design 2 I C Adjustable Overvoltage Protection Trip Level The MAX20330 is designed to drive a single or dual back- to-back external N-channel MOSFET with a low R Wide Adjustable OVLO Threshold Range from 4V ON to 24V (168 steps) (10m max). An external TVS can be used to protect the device from a high energy surge if necessary. Preset Internal Accurate OVLO Thresholds: 6.8V2% The device is available in an 8-bump (0.35mm pitch, Additional Protection Features Increase System 1.77mm x 1.03mm) wafer-level package (WLP) and oper- ate over the -40C to +85C extended temperature range.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Note 1: The external TVS clamp voltage should be below the abs max of MAX20330. Package Information PACKAGE TYPE: 8 WLP Package Code W81B1+1 Outline Number 21-100229 Land Pattern Number Refer to Application Note 1891 THERMAL RESISTANCE, FOUR-LAYER BOARD Junction to Ambient ( ) 91.72C/W JA For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a +, , or - in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing per- tains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
