Maximum output current of SM72442

Other Parts Discussed in Thread: SM72442

Hello All,

My question is related to the voltage divider containing RB3 and RT3. This voltage divider is connected to PIN A4 of SM72442 and is used for output current limiting. According to voltage divider rule maximum voltage that can appear at PIN A4 is 5V since the supply is of this potential.

Question 1: What is the maximum output current that can be limited using PIN A4?

Question 2: Is additional current sensing amplifier needed to be attached as there is a box in Typical Application Note of SM72442 ?

Thanks

Regards,

Noman
