1.1 Overview
The STEVAL-IFP046V1 embeds the IPS1025HQ-32 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 an optical isolation implemented through three optocouplers (ISO1,
ISO2, and ISO3) for signal forward to the device and FLT pins for feedback diagnostic signals.
The expansion board features:
•
Based on the IPS1025HQ-32 single high-side switch, which features:
– Operating range up to 60 V
– Low-power dissipation (R
ON(MAX)
= 25 mΩ)
– Fast decay for inductive loads
– Smart driving of capacitive loads
– Undervoltage lock-out
– Overload and overtemperature protections
– QFN48L 8x6 mm package
• Application board operating range: 8 to 33 V/0 to 5.7 A
• Extended voltage operating range (J3 open) up to 60 V
• Green LED for output on/off status
• Red LEDs for overload and overheating diagnostics
• 5 kV galvanic isolation
• Supply rail reverse polarity protection
• Compatible with STM32 Nucleo development boards
• Equipped with Arduino UNO R3 connectors
• CE certified
• RoHS and China RoHS compliant
• Not FCC approved for resale
