Hi there guys,
I've recently come across a PCF8655 LCD driver IC that I am trying to control my LCD with. It is not a cascaded application and the PCB-setup is a direct copy of Figure 4 on pg. 7 in the datasheet provided ( http://www.nxp.com/documents/data_sheet/PCF8566.pdf )
VDD: 3.3V
VLCD: 0V...
Hi there,
I am currently working with a system that we are going to make portable for the first time. Hence, are we in need of a battery and a battery charging system. Can you give advise on an IC for charging, a battery and charger?
Requirements: Lithium Ion battery (4.2 V), about 1500 mAh or...
Hi, this is probably a simple question but i need a supply voltage of 70+ V. The "start voltage" is a battery with 9V. I am currently using MC34063 from ST electronics (dc-dc step-up converter). This circuit delivers 38V output.
How can i step up the voltage further? Can I invert the 38+ (to...
Hi all!
I currently work with electrical muscle stimulation and need some advice on electrical safety and indications.
I will be working with opto-couplers with an output of maximum 40 mA, I therefore need an electrical component that indicates if the current is higher than the maximum allowed...
Hi,
Im currently involved in a product development. The product is comprised of several vibration nodes. Each node shall be controlled with respect to frequency and intensity.
The requirements are:
---------------------------
Frequency range: 5-400 Hz (might be modified to ~100-250 Hz)...
