The 12V protected switch board comes with BTS50010-1TAE, an ultra-low ohmic smart high-side power switch from the Power PROFET™ family used as Solid State Relay (SSR) to drive the starter motor of a scooter or a motorcycle with an engine smaller than 150 cc and cabling length of up to 3 meter. Its typical RDS(ON) is 1.0mΩ and it can drive a nominal DC current of up to 40A, with an outstanding inrush capability up to 250 A. The demo board is designed in a very compact form (44.5 mm x 26.5 mm) to provide a space-optimized solution. On this demo board version, D2 and R1 are not assembled. We offer an additionalboard versionwhere D2 and R2 are assembled. Further information for this board is available in the productapplication note
