TPS61170: Thermal Shutdown Befavior

Part Number: TPS61170

Hello team,

Can you check information regarding the below questions?

1. Thermal Shutdown condition on datasheet: Do we have rough min/max value?

2. Behavior during Thermal Shutdown: What behavior can we use to determine thermal shutdown behavior?

3. Thermal Shutdown hysteresis: Does the thermal shutdown completely shut down until the temperature has dropped by 15C? Or does TPS61170 operate for a moment on a cycle-by-cycle, like over-current protection?

Best regards,


  • Hi Shotaro,

    Here are the comments regarding the three questions:

    1. I need to check and give you the feedback tomorrow.
    2. A typical behavior after thermal shutdown triggered is no SW switching.
    3. When thermal shutdown is triggered, the device shutdown completely until the temperature has dropped by around 15C.



  • Hi Shotaro,

    Regarding the first question, a rough estimation of the thermal shutdown threshold will be min 145C and max 175C.
