Protected 5–34 V high-side outputs for 12/24 V loads
The ET-MD17 is built around the 2 × Infineon BSP452 — protected high-side switch, 5–34V, 0.5A, 160mΩ, internal inductive clamp. It runs from VBB 5–34V (12V / 24V industrial).
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Valves and solenoids on 24 V
- Automotive 12 V loads
- PLC-style outputs
