Hi Ti experts,

Please help me review the TLIN1021A-Q1 CIRCUIT:

TLIN1021ADRBRQ1.pptx

NOTE:  P_5V_KA and P_VBAT_FIL are always ON power sources

My requirements include:LIN is an wake up source and it should consume minimum current in sleep.

Could also clarify what would be the current be in sleep when the typical case of 25C temperature as the below table only signifies max sleep current.

    Hi Vinyas,

    The schematic looks good overall. Would recommend 100 nF on VSUP similar to figure 12-1 and for the 220 pF bus cap placed closer to the device while the TVS diode closer to the connector.

    Also, ~ 9 uA is typical for 25 C, thanks.

    Best Regards,

    Michael.
