MAX20313MAX20316 500mA to 6A Adjustable 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 Amplifiers 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.

Package Information PACKAGE TYPE: 12 WLP Package Code W121K1+1 Outline Number 21-100118 Land Pattern Number Refer to Application Note 1891 THERMAL RESISTANCE, FOUR-LAYER BOARD Junction to Ambient ( ) 72.82C/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 pertains 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.
