TPL5010: The time I set for 5 minutes takes 9 minutes.

Adam Austin

Part Number: TPL5010

Hello, I am using the TPL501010DDCR integration, but the timing I set for 5 minutes resets after 9 minutes at the earliest. I use 43k as timing resistor.

Hi Adam,

Could you add a shunt resistor (10kΩ) to the DONE pin? That is probably the only reason why you did not get correct timing.

Should I do something like that?

Hi Adam,

Like this, a shunt resistor to GND.
