Hello Team, SLG59M1717V obviously does not have reverse current protection. For a bidirectional charging application in a mobile product, can we leverage this to behave as an ideal diode so that a higher output voltage applied can be passed thru the mosfet channel rather than only the body diode?For example. VDD=2.5VVIN=3.3VVDD=open ckt -> 5V Applied. Secondly, how much current can safely pass through the body diode?BestDCM
Hi,
For reverse current blocking you can check :-SLG59M1714V
For bidirectional application , you can refer below application note :-AN-CM-268 Applying the GreenFET Load Switches in Bidirectional Applications (renesas.com)
Thanks

Hello,The SLG59M1717V lacks reverse current protection, so it cannot inherently function as an ideal diode for bidirectional charging. However, you can explore external circuit configurations, such as back-to-back MOSFETs, to achieve ideal diode behavior. Regarding the body diode, its safe current limit depends on thermal constraints and the specific application. Refer to the datasheet for precise current ratings and thermal considerations.
