TL7700-SEP: Maximum current rate through the BJT in the RESET pin.

Moral Assraf

Part Number: TL7700-SEP

Hi,

I'm looking to use TL7700-SEP RESET pin as a switch for another circuit, but I need the current (from the RESET Pin to the GND) to be 8mA up to 25mA.

Is it possible?

Thanks,

Moral.

Hi Moral,

The current sinking capability of the RESET pin is listed in the TL7700-SEP datasheet under the name "I_OL" and has a maximum recommended value of 3 mA and an absolute maximum value of 5 mA.

Since your desired current is higher than the maximum recommended value, an additional transistor should be connected to the RESET pin for this load.

Thanks,

Andy
