MAX20314

500mA to 6A Adjustable Current-Limit Switches

Adjustable Current Limit with high-accuracy and low-Ron up to 6A


Please check latest availability status for a specific part variant.

Description

The MAX20313–MAX20316 programmable current-limit switches feature internal current limiting to prevent damage to host devices due to faulty load conditions. These current-limit switches feature a low, 10mΩ (typ) on-resistance and operate from a +2.5V to +5.5V input voltage range. The current limit is adjustable from 500mA to 6A, making these devices ideal for charging a large load capacitor and for high-current load-switching applications.

The MAX20313 and MAX20315 feature a continuous current-limit mode during an overcurrent event. The MAX20314 and MAX20316 feature a latchoff mode during an overcurrent event. Additional safety features include thermal shutdown protection to prevent overheating and reverse current blocking to prevent current from being driven back into the source.

The devices are available in a 12-bump (0.4mm pitch, 1.68mm x 1.48mm) wafer-level package (WLP) and operate over the -40°C to +85°C extended temperature range.
