MAX14523A/MAX14523AL/

MAX14523B/MAX14523C

250mA to 1.5A, Adjustable

Current-Limit Switches

General Description

Beneﬁts and Features

The MAX14523A/MAX14523AL/MAX14523B/MAX14523C

programmable current-limit switches feature internal cur-

rent 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.

● Accurate (±10%) Overload Current Limit

● Adjustable Current-Limit Threshold

● Low-Dropout Voltage (70mV at 1A Load Current)

● Short-Circuit Protection

● Thermal-Shutdown Protection

● Reverse-Current Protection

● 170μA (typ) Supply Current

● Shutdown Reverse Current, 0.6μA (max)

● +1.7V to +5.5V Supply Voltage Range

● Tiny 8-Pin, 3mm x 3mm, TDFN Package

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 safe-

ty features include thermal shutdown to prevent overheat-

ing and reverse-current blocking to prevent current from

being driven back into the source.

perature range.
