STL160NS3LLH7
Posted on August 17, 2017 at 07:06We have purchased 10 qty of STL160NS3LLH7 MOSFET IC. We found that Drain to source impedance of MOSFETs is varying( NOTE : MOSFET were not connected to any external circuitry while measuring impedance using DMM). Fo...
Question about Half-Bridge Output using L99MM70XP
Posted on August 08, 2017 at 12:15I am using L99MM70XP SBC.I have one question about Half-Bridge Output.Below Condtions, I think that All Half-Bridge output is Low (Open States)All High-Side / Low-Side Switch is Open. I think that PIN output Value i...
Remnants of stall detection in L6472 and L6482 datasheets
Posted on August 21, 2017 at 12:34Hiho,there are still remaining hints of stall/step loss detection (for example at the description of the FLAG pin) in the datasheets of the above mentioned ICs although they are only implemented in the L6480/L6470. ...
