Part Number: TPL0102-100
I had used TPL0102-100 as the current limit controller and my application is TOF camera. My schematic is below:
On the same PCB, I had SMT the old part before 2 years ago by sample from Avnet and can work fine. But recently, I buy new item from Mouser and it is not work after SMT on the same PCB.
Below is parameter when module operation with Voxel viewer:
Voltage of RVar = 388mV
Voltage of WB pin in TPL0102:
Work fine item: 130mV~188mV (can control by Illumination Power in Voxel viewer(100%~50%) )
Work NG item: 193mV (can't control by Illumination Power in Voxel viewer )
Below is scope capture the I2C pic, Red line=I2C_SLV_SCL_3V3, Green line=I2C_SLV_SDA_3V3:
Could you kindly give me support to clarify if the device defective?
In reply to Uttam Sahu:
I think your concern is the red arrow in below image,right? (UP is working device, DOWN is non-working device)
I think they are ACK from device and data return from device, so is it the issue for I2C tool ?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
