Power management

STM32MP1 not recovering on variable power SUPPLY, start from 0v to and rise to 5V and vice versa.

STPMIC1APQR is a PMIC, how to recover from lock state, as the STM32MP1 RTSn pin is not going to HIGH , and this situation on power variable supply decrease down to 1 v and then back to 5 v1. no log is observed on console during not power up variable ...

I plan to use an STPMIC1 to power a STM32MP157A with DDR3L. The only PMIC in stock is the STPMIC1E. For this particular case, will we have to pre-program the STPMIC1E before on a JIG tester or can it initially power the MPU which then programs the PMIC

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...

Hello, is the USB Power Switch STMPS2252TTR UL recognized? Regards, Torsten

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...

On the EVALMASTERGAN1, what's the fastest rise time for the Vgs? Is it programmable on the eval board?

Hello, We use evaluation board PM8805-EVM that support power over Ethernet. We want also allow Rear AUX, but this is not possible There is another evaluation board that support PoE and Rear AUX? Thanks, Anat

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...
