•

Tight Current Limit Accuracy

Product Highlights

Battery-operated electronics as well as battery

chargers need tight current limit accuracy to protect

against overcurrent faults. The MAX17614 with its

±3.3% tight current limit accuracy provides robust

overcurrent protection in these applications.

•

Ideal Diode Operation

• Fast Reverse Current-Blocking Protection(140ns)

• Seamless Power Source Switchover

•

Robust Protection Reduces System Downtime

• Wide Input Supply Range: +4.5V to +60V

• Hot Plug-in Tolerant without transient voltage

suppressor (TVS) up to 35V Input Supply

• Negative Input Tolerance to -65V

Small Total Solution Size

The MAX17614 with its integrated nFETs enables up

to 40% smaller solution size in space-constrained

equipment. Applications include ideal diode

implementations and power source selectors where

the end equipment needs to supply the load from

more than one power source.

Faster Response Times

Faster fault exit response times enable the

MAX17614 to reduce output hold-up capacitor size

up to 50% in Priority Power Source Selector

applications, where the end equipment input supply

transitions between a higher priority power source

and a backup power source.
