250mA to 1.5A, Adjustable

Current-Limit Switches

LB/MAX14523C

General Description

Features

The MAX14523A/MAX14523AL/MAX14523B/MAX14523C

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 70mΩ on-resistance and operate from a

+1.7V to +5.5V input voltage range. The current limit is

adjustable from 250mA to 1.5A, making these devices

ideal for SDIO (secure digital input/output) and other

load-switching applications.

Each device in the family handles an overcurrent event

differently depending on the option selected. The

MAX14523A/MAX14523AL go into an autoretry mode,

the MAX14523B latches off the switch, and the

MAX14523C features a continuous current-limit mode.

Additional safety features include thermal shutdown to

prevent overheating and reverse-current blocking to

prevent current from being driven back into the source.

are available in a tiny 8-pin, 3mm x 3mm, TDFN pack-

age and operate over the -40°C to +125°C automotive

temperature range.
