TCAN1145-Q1: Wake pin

Ivy Jin

Part Number: TCAN1145-Q1

Tool/software:

Hi team,

May I ask if  the Wake pin of the TCAN1145-Q1 can be designed like this, does RC configuration meet the requirements? The customer wants to use this pin to achieve a wake-up on the edge.

LCH1_FSIDE_PSEC_SW is a switch. The requirement is a wake-up of the descent edge of the ground. Suspension voltage is 9-16V

Thanks.

Regards,

Ivy

    Ivy,

    The WAKE pin responds to a falling or rising edge to register a correct wake event. As long as the voltage meets the required thresholds for a logic high and logic low state when transitioning, which are defined in the datasheet, the WAKE event will be registered and wake the device.
