TPS35-Q1: CRST Delay MIN/MAX

Aaron Klijn

Part Number: TPS35-Q1

Tool/software:

The Table "Reset Delay Time for Common Ideal Capacitor Values" shows a MAX/MIN of +/-20%. Does this timing performance apply to all part instances across the rated temperature range of the part? Does the ideal capacitor value remain the same for the +/-20% or is it accounting for temperature value drift of the capacitor as well?

Hi Aaron,

The values in table 8-1 take temperature variation of the part into account. Capacitor variation is not taken into account. The datasheet recommendation is to use low temperature coefficient C0G capacitors.

Thanks for confirming there could be an additional drift based on external capacitor change over temperature. I will assume the "temperature variation of the part" applies across all part instances such that we would never see more than +/-20% contribution strictly from the part.

Yes, the min and max specs are guaranteed to be met by all devices.
