Modifying the voltage setting for one of the voltage regulators in the PMIC entry in the device tree causes the boot up to fail.
hi,we are going to use the STPMIC1E in our design but bc the part is not available we are going to use the STPMIC1B for the initial boards we produce and then change to the desired part.however, the buck4 regulator needs to be changed to 1.2 volts fr...
STPM33: UART is not responding.
Hello,I have design power monitor section using STPM33.I have taken its reference from STPM33 EVK board and its datasheet.I have attached our design schematic. Sensing the current with the shunt resisters.Below are Test point voltages for debug:VREF1...
Resolved! Notched TVS diode
Hi there,I have a blown TVS diode, with code: G30 P436, see attached. Looking at one of the other threads, suggests its SMAJ5.0A-TR. Is there anyway to confirm this? Any help identifying the component will be great. Cheers,
Pulse width Modulation, BEMF and BEMF induced current
Hey guys,I would appreciate your thoughts on this. I have presently implemented 6 PWM schemes to modulate the 2-level 3 phase inverter I am using to control my BLDC motor in a simulation. Those PWM schemes are shown in the figure below I observed tha...
Resolved! Hi, We are planning to use L6491D in our application.
We had the following queries:1.Pins LIN is mentioned as active low.Will the low side PWM output from driver be high when input to LIN pin is low?2.VCC is mentioned to be between 10-20V.But all input pins(SD,HIN,LIN) are operating at 5V level.Is there...
Resolved! TORQUE-SPEED RELATIONSHIP?
I have a question, I am presently working with a bldc motor. And I also did a simulation on matlab.So I observed this:1. when I applied a certain load torque (let’s say 0.4Nm), then I give my controller a set point speed (400RPM) the controller is no...
