Part Number: TPS2663
Other Parts Discussed in Thread: TPS25944L, TPS25944A

Hi Sir 

As I know TPS25942 is I(LIMIT) with Thermal Shutdown and TPS25944 is 4 ms Fault Timer then Shutoff

May I know TPS2663x which part number OCP function is similar with TPS25944 or all of TPS2663 OCP function is the same with TPS25942 ?

    Hello Kai,

    TPS26630 device has OCP function similar to TPS25944.

    Are you looking for Auto-retry or Latched response with OCP? (TPS25944A or TPS25944L)

    In TPS26630 device the fault timer is equal to tCL_PLIM(dly) [=162ms typical]. If thermal shutdown temperature is reached before a time of tCL_PLIM(dly), the device shuts down.

    The auto-retry or latch response can be configured by MODE pin of the device. Please refer to Section 9.3.8.1 on Page 19 and Table 1 on Page 22 of TPS2663 datasheet.
