Other Parts Discussed in Thread: TPS3890, TPS3808
Dear All,
I am using TLC7701IPW device in our current program. We have connected 22uF, X7R capacitor to CT pin to provide 462ms delay as per the formula 2.1 x 10000*Ct. But I have tested at Ambient this circuit on 5 boards, I got delay around 690ms which is not supposed to be. Even if I consider 20% of capacitance tolerance (X7R is 10%) also, delay much not exceed 554ms. Please advise whether is there anything else needs to be considered for delay calculation. Immediate response is great appreciated.
