MAX20313/MAX20314/ 500mA to 6A Adjustable MAX20315/MAX20316 Current-Limit Switches General Description Benefits and Features The MAX20313MAX20316 programmable current-limit Reliable Protection switches feature internal current-limiting to prevent damage Adjustable Current Limit (500mA to 6A) to host devices due to faulty load conditions. These Accurate 5% Overload Current Limit (2A to 6A) Current Monitoring current-limit switches feature a low, 10m (typ) on- resistance and operate from a +2.5V to +5.5V input voltage Low R 10m (typ) ON Reverse Current Protection range. The current limit is adjustable from 500mA to 6A, making these devices ideal for charging a large load Short-Circuit Protection Thermal Shutdown Protection capacitor and for high-current load-switching applications. Space Saving The MAX20313 and MAX20315 feature a continuous current-limit mode during an overcurrent event. The 12 Bump 0.4mm Pitch 1.68mm x 1.48mm WLP MAX20314 and MAX20316 feature a latchoff mode during Applications an overcurrent event. Additional safety features include RF Power Amplifier in Cell Phones thermal shutdown protection to prevent overheating and USB Ports reverse current blocking to prevent current from being Data Modem Cards driven back into the source. Portable Media Players The devices are available in a 12-bump (0.4mm pitch, UTCA/ATCA Platforms 1.68mm x 1.48mm) wafer-level package (WLP) and operate SDXC Card Power Supply Protection over the -40C to +85C extended temperature range.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. 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. Electrical Characteristics (V = 2.5V to 5.5V, T = -40C to +85C, unless otherwise noted.
