EVALUATION KIT AVAILABLE MAX14653/MAX14654/ High-Current Overvoltage Protectors MAX14655/MAX14717 with Adjustable OVLO General Description Benefits and Features Protect High-Power Portable Devices The MAX14653/MAX14654/MAX14655/MAX14717 over- Wide Operating Input Voltage Protection from voltage protection devices feature a low 38m (typ) R ON internal FET and protect low-voltage systems against +2.5V to +28V voltage faults up to +28V . An internal clamp also pro- Integrated 38m (typ) n-Channel MOSFET Switch DC tects the devices from surges up to +80V. When the input Flexible Overvoltage Protection Design voltage exceeds the overvoltage threshold, the internal Adjustable Overvoltage Protection Trip Level FET is turned off to prevent damage to the protected Wide Adjustable OVLO Threshold Range from downstream components. +4V to +20V The overvoltage protection threshold can be adjusted with Preset Internal Accurate OVLO Thresholds: optional external resistors to any voltage between 4V and 15.5V 3.3% (MAX14653) 20V. With the OVLO input set below the external OVLO 6.8V 2.9% (MAX14654/MAX14717) select voltage, the MAX14653/MAX14654/MAX14655/ MAX14717 automatically choose the accurate internal trip 5.825V 3% (MAX14655) thresholds. The internal overvoltage thresholds (OVLO) Additional Protection Features Increase System are preset to 15.5V typical (MAX14653), 6.8V typical Reliability (MAX14654/MAX14717), or 5.825V typical (MAX14655).

The MAX14653/MAX14654/MAX14655/ OVLO Thermal-Shutdown Protection MAX14717 are also protected against overcurrent events by an internal thermal shutdown. Minimize PCB Area The MAX14653/MAX14654/MAX14655/MAX14717 are 12-Bump WLP (1.29mm x 1.83mm) Package offered in a small 12-bump WLP package and operate -40C to +85C Operating Temperature Range over the -40C to +85C extended temperature range.
