Resolved! What should I do with STPMIC1 unused pins ?
Hello,I'm designing a board based on STM32MP1 and we decided to use the STPMIC1A to manage the power. The board is really simple and so we use only the bucks (1 for core, 2 for ddr, 3 for vdd and 4 for extra 3.3). All others (LDOs; boost and switches...
How can avoid overlapping of pwm from different channels?
I am writing a simple 6 step bldc motor control using Hall sensor(Complementary PWM).When I try to switch the pwm(example when HALL input changes from 110 to 101) channel 1 and channel 2 gets over lap.I have inserted Deadtime.One in red is channel 1...
Resolved! 16 Channel Adjustable Constant Current LED Driver
I'm looking for a drop in replacement for the TI TLC5926IPWPR LED driver.It's 16 channel constant current LED driver. Max current is set via an external resistor, but we can also adjust the current via the SPI interface.Does ST have this as well? I d...
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 ...
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,
