MAX20313EWC+T MAXIM Current & Power Monitors & Regulators 500-6000mA Adjustable Current Limiting Switch; EN active high; continuous mode

1.General 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) onresistance 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
