Small Total Solution Size (Sensor Systems)
Increased need for integrating more functionality in
smaller form factors limits board space allocated for
power and protection circuitry in factory automation
and building automation applications. By integrating
both forward and reverse MOSFETs, current sense,
input/output reverse polarity protection, forward and
reverse overcurrent protection, and UVLO/OVLO all
into a single chip, the MAX17615 needs only 1/8th of
the total solution size compared to solutions that use
discrete components to implement the same
protection features.

Output Reverse Polarity Protection (Process
Instrumentation, PLC, Network Modules)
Factory automation applications that provide a 24V
output to remote equipment are liable to experience
a reverse polarity voltage applied across their output
terminals due to cable wiring error. The MAX17615
offers robust protection for such scenarios and
prevents expensive equipment failure and service
costs.
•
Tight Current Limit Accuracy (Condition Monitoring,
Battery Operated Modules)
Battery operated electronics as well as battery
chargers need tight current limit accuracy to protect
against overcurrent faults. The MAX17615 with its
±5% tight current limit accuracy provides robust
overcurrent protection in these applications.
