BTA16-800BW
Triac snubberless (bta-16-800bw) does not require a snubber in the circuit?Or would installing a snubber in the circuit have a good effect?The difference between BTA16-800BW and CW is the gate current difference.Will the current specification selecti...
Issue with ST1PS02 step-down converter
We are currently using the ST1PS02BQTR for powering a compact main board with BT connectivity (STM32WB5MMG), an IMU, and other ancillary blocks (LEDs, charge pump for LEDs, passives). The system is powered through two AAA batteries connected in serie...
Resolved! How to add the electronic load to the STEVAL-WLC38RX to simulate wireless charging of a smartphone
Hello everyone, to simulate wireless charging of a smartphone (I want to achieve 5W transmission to the load), I need to use an electronic load and add the load step by step. Since the wireless charging system cannot immediately absorb high current, ...
SMPS Pulsing in hiccup mode
Hello, I have designed and assembled a SMPS based on the EVAL-STCH03-45W evaluation board. What I have noticed, is that the power supply is outputting 1 Hz pulses with short buzzing sounds. These symptoms usually mean the hiccup mode is activated. Ho...
L4986 startup problems with external VCC supply
I am evaluating a PFC with the EVL4986-350W evaluation board.To be able to use Boost coils without the extra winding I want to supply the VCC voltage from a buck converter connected to the output voltage. The voltage from the buck is 17V.I have tried...
PowerSTEP01 - is the ResetDevice command conditional?
I have a PowerSTEP01 that is behaving unexpectedly when I send the ResetDevice command.If I send it when my system starts then everything is ok when I check the STATUS register.However, if I send ResetDevice after the motor has been moved (sequence e...
SPV1050 with low volatge PV cell and Supercap
Dear allI use an STEVAL-ISV019V1 (Boost Mode) with a KXOB25-05X3F PV cell.When I connect a 330mF supercap to BATT, working at low light (200Lux) Store is being charged withing 30s. Not the SPV1050 tries to switch to the Supercap and restarts because ...
L293D
Hi everyone, I'm just starting in this field and I'm designing my first product. I'm designing a device that will use the L293D microchip and I'd like clarification on the following issues:1) There is a maximum value for the high voltage input curren...
Disable L6924D maximum charging time
According to datasheet, L6924D has the possibility to set a maximum charging time, defined according to the capacitor connected in TPRG pin. But what should be done if the maximum charging time limit is undesirable? Can I short TPRG to GND to achieve...
