Dear All,I've a problem with my step-down regulator L7985A.On power up, the DC / DC is activated when the ENABLE pin reaches about 880mV, while on the datashhet it is reported 1.2V as the ON threshold.Can you explain to me what this difference is due...
HI Sir, May I ask you for the help due to the quality issue of TIP147, functional fail,Customer would like to known what the problems and want to get analysis report,Attached is the picture for the component, what the information needed to provide th...
Hello, we have a L9907 evaluation kit and we are trying implement the software to get L9907 to run. We have some problems we need support for:we supply the board at 24V and are using the VBAT_Scal circuitry to scale down the voltage on the VB pin, bu...
Our BLDS motor becomes warm/hot at no load, at room temperature. In our application the surrounding temperature is more then ambient up until 55°C. Any addition heat that we generate inside the motor will cause the motor to quickly overheat, with pos...
I am using an STS10N3LH5 on the low side of a half bridge circuit. I have a schottky diode across the motor. For lighting applications we PWM the ground and everything is fine. However, during motor applications we PWM the high side and will somet...
I want to design a Li-ion battery charger.Q1. How charge will know that it should work in constant current or constant voltage mode?Q2. How same charger can be configured for constant voltage and constant current operation?Regards,Vivek
HiI have been testing the following circuit (which apparently works). I am finding that the TRIAC (BTA16-600BW) does not turn off with an inductive load (induction motor at 240V, 3A. 50Hz) yet with a simple house lamp the circuit works switching the ...
I recently faced an issue regarding my evaluation board STSW-SPIN3202. I was uploading the firmware to my board but unable to upload due to update issues. So, I have connected the ST-Link V2 to the board and connected it with the utility software pro...
