L6924D: How to Derive ICHG from Current Injected in REND?
Posted on August 30, 2016 at 21:00Hello,The datasheet of the L6924D mentions on Page 19 that the the current injected in REND is proportional to ICHG. It also states that the voltage across REND can be used by a microcontroller to check the charge s...
No stabilization of output voltage | SPV1040
Posted on August 30, 2016 at 19:21Hi. I designed the power converter which is supply from the photovoltaic cell ( Umax = 5.5 V / 1 W) on a SPV1040. The problem is that the system did not stabilize the output voltage.The output voltage is proportiona...
PowerSTEP01 Manufacturing Delays
Posted on August 18, 2016 at 14:44Hi all.I recently developed a system that uses the PowerSTEP01 devices. I had great trouble getting hold of the devices when I originally prototyped the design. Now I've come to order another batch and no body seems...
SPV1020 SPI extract data
Posted on August 12, 2016 at 00:39Hi, I design a battery charger with SPV1020 and DN0023. It's works ok. So I connect trought SPI with a uC. I read the different registers succefully. But I want to know what is the scale for register 0x04 (Read Curr...
A6986F current consumption is more
Posted on August 02, 2016 at 08:37Hi All, We are using A6986 ic our board to convert 12V to 5V, but ic itlsef taking more current, its 3.50 mA. Here i am attaching the my part of schematic. Kindly look at it and let me know what may be the problem.
Interfacing STLED316 with Atmega
Posted on August 01, 2016 at 22:00Hello! With Atmega regular hardware SPI, data transfer is 8-bit. Hence, when asserting commands, followed by receiving/transmitting data from/to STLED, each transmission will look like 2 8-bit packets separated by h...
High voltage input to 7805
Posted on July 29, 2016 at 15:00Hello,We are using L78M05CDT-TR in our design since few years. We are satisfied with the result of product. However we are making new design (PFA) and we considering to use design suggested in datasheet for high volta...
L6920D breaks after battery insertion
Posted on July 27, 2016 at 11:44Dear all,I'm using an L6920d to generate a 3V3 voltage to power up a circuit from 2 alkaline battery. However it happens that sometimes the component breaks after inserting the batteries (its imput impedance go down t...
