Dear allI have built up the circuit of STEVAL-ISV019V1. I want to conserve power over one night in a supercap connected to VSTORE. With the 3V3 LDO enabled but no load present, the SPV1050 seems to draw about 7-8uA.Is it possible to bring it down to ...
Hello,I created a custom board using the TCPP03-M20, based mostly on the NUCLEO H7S3 schematic.The only differences are:* My uC is using 1.8V, so the EN pin only gets 1.8V* VCC_VCONN is supplied with 5V instead of 3.3V* I use a single power path (usi...
Hi all,I have a board designed using the STWLC38 as the Qi Rx. An ESP32 is the host controller using I2C to configure the STWLC38. The communication works OK and I can set and read various registers.I have two questions on this configuration:The STWL...
Hi,I am looking to use the STM6710DWB6F as a quad-channel voltage supervisor, specifically for 3.3V, 5V, 6V and 12V rails. The datasheet specifies V1IN = 5V, V2IN = 3.3V, V3IN = 1.8V, and V4IN = adjustable. It seems obvious use V1IN and V2IN direct...
From what I can read on this diode it is from ST for sure, and it says G beside the logo, the next line is BEX, and the last line is GP048. Any help would be appreciated
Hi ST teams,I am currently planning to develop a project using the STWBC2 series. However, I have found that the technical resources available on the official website are very limited. Could you please provide or recommend a more comprehensive set of...
Dear Forum members. Could you please help me with a .PDF version of the suggested PCB footprint for the LDLL16EN (QFN32L 5x5 mm package) not the Ultra librarian or Samac Sys options. The plane original pdf version. Thank you
Dear Forum members. Could you please help me with a .PDF version of the suggested PCB footprint for the L99LDLH32TR (QFN48L 7x7 package) not the Ultra librarian or Samac Sys options. The plane original pdf version. Thank you
Hi everybodyI need some help to identify this ST micro diode , can anybody point me in the right direction please?I have tried searching for the numbers on the diode with no luck.regardswasim
Hi, I am trying to configure the L9026 through SPI communication, but I am confused about configuring the CFG_1 and CFG_2 registers. In section 7.4.1 (PWM Generator), it is mentioned as CFG_1.PWM_DIV_GEN, but in the CFG_1 register there is no fie...
