Resolved! ST1S12 quiescent current is too high
We are using an ST1S12GR device and the input current is >2.5mA even with only the feedback loop connected and ENable pin connected to Vin. Feedback resistors values are 220k resp. 59k. According to Datasheet Table 8 (“Electrical Characteristics�?) Q...
Resolved! L6924U - how to connect IUSB pin in AC mode
We are considering to use L6924U for a new design for a battery charging circuit in our industrial wireless remote controller project. If we set up L6924U for AC input (MODE grounded), do we need to do anything with IUSB pin? Can we just ground it (w...
Resolved! L6470PD - motor speed vs. clock setting
We are using L6470PD driver IC for driving 2-phase stepping motor. Problem is related to external clock and internal clock setting in L6470.In fact, we noticed different motor rotation speed when we switch between external clock of 16MHz and internal...
Resolved! Over Current Protection (OCP) of VIPer06
We are building a 115kHz SMPS transformer that is being used in a circuit using a VIPER06HS. It is in the circuit with my transformer that is outputting 5 volts at 200mA the OCP is tripping off the VIPER unit. I would like to know how the OCP works. ...
Resolved! Stand-alone use of STM32 CPU in STSPIN32F0
We would like to use the embedded STM32 in the SPIN for calculation purposes if no Vm power supply voltage is available.But datasheet is mentioning that Vdd < Vm. And the circuit diagram shows connections between Vdd, Vdda and internal 3.3V.Question ...
RHFL4913 and RHFL7913
Datasheet, It is recommended to insert a capacitor between ADJ - Vo of RHFL7913 and RHFL4913. The capacitor value is 470 nF for RHFL7913. On the other hand, 47 nF is recommended for RHFL 4913. Does the value differ by one digit due to the difference ...
L6206 initial state (IHM04A1 board)
Hi everyone. I'm working on to drive 3 wheel omniwheel system for our project. I'm using parallel connection to have larger current. I realize that when i connect all the input and enable pins to ground (logic 0), all the leds connected to the outpu...
PWD13F60 Interference between MOSFET pairs in full-bridge frequency converter
Hello to everyone. I'm making a 200W frequency converter for motor driving with APFC (~85...265 AC input) at my own 2-layers PCB and have some questions about influence from one half-bridge to another half-bridge inside the IC. Parts are driven in u...
How to control Speed of Eval6229pd
Hi,I have Eval6229pd and I am having trouble in controlling of speed. It was controlling via arduino pwm. when vref is adjust there is no effect in terms of speed. So I was adjusting it by fwd/rev but the certain speed that I'd expect was not met. Is...
