Hi, Request help technical consult: We search doing solution for dock hub station with interface out ( HDMI + USB 3.0) + power-bank functionally(with support powered/charged through VBUS simultaneously battery pack... I have two questions on TJA1145. 1.In TJA1145 Under voltage detection time 54µs(mentioned on Datasheet) and under voltage detection to sleep mode time 200mS(as mentioned on datasheet), What will happen if TJA11... In chapter 5 of PF8200D2 configuration report <https://www.nxp.com/docs/en/supporting-information/R_PF8200D2.PDF>. It shows SW7/LDO1~4/PGOOD are OFF when power up. Is that means LDO1~4 are keep OFF when PF8200... Hi, We are using the PF8200DB and PF8200ES in a new design and were looking for a signal to monitor to check that the PMICs had turned on successfully (closed loop boot process). In the OTP reports for each chip, it ... In one of our application i need to use this MCU with 100u Ohms shunt on positive side of the battery . When i tried the same with load , I am not getting the proper values of voltage and current . Please confirm. Hi ? Question : Airfast RF Power GaN Transistor, A3G20S250-01S 1. How much is the price of above part ? ... Hi , I need the reference manual and power consumption for MC33FS6523CAE. It will be better if you could share the power consumption sheet. currently my activity is to test the power rails of board so I... About the problem of mmpf0100npaep power chip, the attachment is the schematic diagram. The order of power on is 1v-> 1.8v-> 1.5v-> 3.3v-> 0.75v. Use RAM to burn into my script, and sw4 output 1.5v every t... Hi what is the value of VSYS on MC32BC3770CSR2 during boost mode? I have written code to talk to the MC33771 part. After initialization of the INIT register I can read registers and get what appears to be good data with valid CRCs without fail for what appears to be exactly 1 second... Do you have the solution about digital power by MC56F8xxxx ? Where I can find all of digital power solution disign ahout MC56F8xxxx ? Is there some solution in Solar Inverters by MC56F8xxxx? Hi, I am using TEA1792, a synchronous rectifier controller, as the controller for MOSFET in a three-phase rectifier. The simplified schematic is as illustrated: The schematic of the two right-most TEA1792s is shown... Hello, I now use the low power VLLS3 mode of KV10Z32, using the wakeup function of the LLWU, but the program will not wake up using the PTC3 (LLWU _ P7) and request help. thanks you the following is the code void BO... Hi， I use The Resonant SMPS Design Tool for a powersupply design with an input of 90V-264Vac and output of 57Vdc/9A.But I can't understand something about the transformer.Please see the attached file. There is ... During brownout testing of a PF1550 design, it was observed that the VBUS_LIN_ILIM setting was resetting to the default value (0x68 400mA) after it was previously set to the desired value of (0xA0 1500mA). Whe... Once I program the SBC(to normal mode) it seems that the watchdog turns off the microcontroller power supply, and this causes that I can't flash my microcontroller anymore, I don't know if there is a way to avoid this... I am using FS6513 with an input of 24V. Only portion upto Vpre is populated. The Vcore portion is disconnected. Every Time the power supply is turned on the Voltage on Vpre rises upto 6.5V but dies down to zero exactl... Hi On a custom board design, I'm using the PF3000A1 for the power supply of an IMX7D. The VDD_ARM voltage is connected to SW1A (1.1V), the VDD_SOC is connected to SW1B (1V). I'm measuring the current through t... Latest spec for i.MX8QM has VDD_MEMC Maximum Supply Currents (Table 10) increased from 2.5A (supported by PF8x00 BUCK5) to 3.2A. What is the recommendation to provide this extra current?
