MPM3530
What is the voltage rating of the Enable pin? 60V? 6V? 4V?
In the typical application diagram on page 1 of the datasheet, it is pulled up to the supply.
Hi yoshinori.kodama,
Thank you for posting to the MPS Forums! The enable pin on the MPM3530 is internally clamped using a 6.5V Zener diode. The pin can connected directly to a voltage source with an amplitude <= 6V without damaging the Zener diode. It is also possible to drive it with a higher voltage (such as connecting it to Vin) using a pull-up resistor to limit its sink current below 150uA. More details on the enable pin can be found on page 12 of the datasheet:
Hi Isabella,
Thank you for your reply. I understand.
