L9305 SPI example
Hello There, Where can I find the example code for interfacing L9305 through SPI? Please suggest some sample Code.
Resolved! STEF033AJR usage
From Figure 12.STEF033 cannot be used for the case Ilim=1A?Rlimit is valid when the value is more than 120 ohm?
Resolved! PM8805 PoE Classification issues
Hi everyone, I'm working on a prototype, which is using a PM8805 to classify connected PoE types. However we are running into an issue, where neither T0, T1 or T2 are giving us any signals (giving always 1 on their open drain signals, making .the LED...
New L6470 / powerSTEP01 successor with better sensorless detection?
Hello,We are currently looking ahead at future options for stepper-motor control and are interested in ST’s longer-term direction beyond L6470 and powerSTEP01.For our application, sensorless detection of stall, obstruction/collision, and increased fr...
L6591 PWM controller
Hi ST team,We are going to design variable programable power supply based on PFC + half bridge PWM controller (with fixed transformer turns ratio). Below is the requirementFor Model 1 Vout (Half bridge converter): 3V-63V/5A (180W maximum with auto ra...
Resolved! STPMIC1 BSTOUT Continous output current
Hello,In the STPMIC datasheet, the BSTOUT continous current is specified as being greater than 1.1 A when 3.3 V < VIn < 5.5 V.If the voltage Vin is greater than 4.5 V, does the BSTOUT continous current increase?I assume so, since the inductor's pe...
Resolved! SPV1050 sample time
The Tsample value doesn't reach the published value (between 0.3 and 0.5 s, and from my measurements between 0.3 and 0.35 s) until Vstore reaches the EOC threshold. Before, it is just around 80 ms. Once EOC is reached and when Vstore decreases again ...
Resolved! Wide output range with L6598D
Hi ST team,We are going to use L6598D PWM controller (Half bridge topology) followed by PFC IC L4985B for our variable power supply design.We need two models for variable (programable) power supply (Model 1 & Model 2) as below specifications. So, can...
Reflow and Pin-in-Paste Compatibility for VNP Series TO-220
Hi, We are currently using the parts listed below and would like to confirm if they are reflow compatible. We plan to use a paste-in-hole (pin-in-paste) process for these through-hole components during SMT assembly. Could you please advise if the fol...
