Count
• 20-Pin, 4mm x 4mm, TQFN-EP Package
• Integrated Back-to-Back nFETs
• Tight Current Limit Accuracy
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.

Key Applications
• 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.
