Mystery IC number ?
Hello allI don't know if this is the right sub-forum, I chose the one that seemed the closest.I've been spending a bunch of time trying to find the part number of a seemingly simple IC, but just hitting walls. I've Googled using the manufacturers nam...
L9916 Programming Mode
We are evaluating the L9916 IC and need to test it with different settings. We are following the information in the Datasheet and the Programming App Note. We keep the IGN, PHASE and LAMP pins at 0V right until the moment we send the ignition sequenc...
Precision voltage reference with low 1/f noise
Hi all, I am looking for two voltage references to produce two rails ( positive and negative) with low frequency noise.The voltage reference does not need to have a tight output voltage accuracy and long term precision. It needs to be stable over a 1...
LM317 adjustable voltage setting question
I'm reviewing the datasheet for the LM317 linear regulator, and it lists the equation for calculating voltage as:VO = VREF (1 + R2/R1) + IADJ R2If I plug in the numbers from my circuit (and neglect the error calculation), I get:1.25 * (1+(1400/400)) ...
About High Side Driver Selection
Hello everyone,I am finding to drive for 4 cabin lock. For this, VNxxx or VNQxxx series help me. I don't need high current. It is 1 amper per channel(per output. I'm looking for a chip that will not cause any supply problems and will be produced con...

SPV1040 IC Burns
@TDK , @Peter BENSCH we are facing SPV1040 IC failure (burns) in the field, after around 3 months of installation, attached schematic and our solar Panel speciation Voc:4.55V, Vm:3.85V, ISC:1026mA, Im:950mA.Battery spec - 9000mAh, 4.2V Lithium ion.
Explain RC filter of STGIB8CH60TS-E Smart Shutdown Circuit?
Hi everyone,I’m using the STGIB8CH60TS-E IPM in my motor drive design and trying to configure the smart shutdown (overcurrent protection) function using the CIN pin.As per the datasheet, the internal comparator reference voltage (Vref) is typically 5...
powerstep01 (stepper motor skipping steps after few hours of operation)
Which alarm to read if our motor skips steps while moving? The motor works fine for a period of time like for 4hours and then randomly starts to skip step while moving in forward direction whereas in backward direction it moves fine. We are using 1/4...
