Overview
The
intelligent power switch (IPS), featuring overcurrent and
overtemperature protection for safe output load control.
The board is designed to meet application requirements in terms of galvanic isolation between user and power
interfaces. This requirement is satisfied by optical isolation implemented through four optocouplers (ISO1, ISO2,
ISO3 and ISO4) for signal forward to the device and FLT pins for feedback diagnostic signals.
The
features:
•
Based on
dual high-side switch, which features:
–
Operating range up to 60 V/2.5 A
–
Low power dissipation (R
ON(MAX)
= 50 mΩ)
–
Fast decay for inductive loads
–
Smart driving of capacitive load
–
Under-voltage lock-out
–
Per-channel overload and over-temperature protections
–
