I want to know how much time delay there will be between the comparative output matching and the pin output. Is the delay fixed?
Using STM32F407 comparative output function, we generate 57600Hz square wave. I find that there are some fluctuations in square wave. Observed by oscilloscope, the rising and falling edges of square wave have several ns fluctuations. So I want to kno...
L6470PD - Isolate Power Line
I am designing stepper driever using L6470PD.Is it possible to isolate system power and motor driver power?I wonder L6470PD internal connection. Is there related document?I want to design power line like the picture below
How to calculate the right Capacitor for Qi charging coil?
Dear Forum,currently I'm implementing a design with the STWLC33 and in the datasheet is a reference design for a coil with L = 8 uH and a C = 3.9 nF. I calculated the resulting resonance frequency and got about f = 90 kHz (with Cser and Cpar). Shoul...
Overcurrent protection function of L6470h
Hi,I designed a board with L6470h and tested it. I am confused with the Overcurrent protection function. It is shown that the capability of L6470h is 7.0 A peak current (3.0 A r.m.s.), but the MAX overcurrent threshold can be set to 6A in register...
STEVAL-IPFC01V1 capacitor bank problem
Dear all,we are evaluating STEVAL-IPFC01V1 board which is a PFC converter and we are experiences problems when we change capacitor bank to larger value. At default board is equipped with4x470uF, which we later changed to 4x1000uF plus 4x470uF. If we ...
STPM34 Minimum measurement time for U/I RMS values
Hi.I have a load switched by Triac, on which I perform a measurement with STPM34.I need to perform a very quick U/I RMS measurement (load is switched on/off)RMS computation is said to be performed on a 200ms window.But it seems I need to perform a ùe...
Resolved! Is there any package information on STPMIC1?
I can just get WFQFN 5X6X0.8 P0.4Much limitted!Thanks for any help.
Resolved! Diode Capacitance
I am looking at using the STTH112RL diode in a gate drive circuit. I was trying to find the capacitance of the diode but it is not in the data sheet. Can you please send me that information?NOTE: This question and answer originated from a customer su...
