SM74611 : time of recharge?

Part Number: SM74611

Hi I am now using this part instead of a diode to block reverse current. Our voltage is 3.3V and the current is about 100mA. Seen from another thread, there will be no problem. The biggest problem is the recharge time of TR. Can you tell if the recharge time is ms or us??

  • Hi,

    As you can see in the waveform  snapshot from datasheet, the internal FET is turned ON for ~100ms and is turned OFF (during which the internal charge pump will be recharged) for ~4ms.

    So, for 4ms the current will flow through the body diode of the FET.
