UCC15241-Q1: PG maximum Sink Current

Steve S

Part Number: UCC15241-Q1

Dear TI,

I've seen in the datasheet that the PG voltage is 0.5V (when driven low) under a 5mA load, however, I can't see any information regarding the maximum current that the PG pin can sink?

Best regards,

Steve

    Steve,

    /PG is an open drain output and we do not test for max sink current. From the description shown in the parametric test condition VSAT=500mV and ISINK=5mA. This implies a pullup resistor R_pu=(5V-0.5V)/5mA=900Ω bur it's more typical to use something near 10kΩ. 

    Regards,
