Original question:

TPS2HB16-Q1: normal operation of channel 1 while channel 2 is open due to over current

TPS2HB16-Q1: Dual channel in ASIL-C

Part Number: TPS2HB16-Q1


Hello,

my customer wants to understand if he can switch two domains with each channel in his design and be ASIl-C compliant.

One channel is supplying a heater the other an MCU.

Its clear that on the TPS2HB16-Q1 fault handling is performed on a channel by channel basis. So if one channel is in the fault state it does not mean both channels will turn off.

my customers concern is if one channels (e.g heater) of the Component failed as a Physical Damage due to over heat, The other channel (MCU) portion is Protected?

 

Can we ensure that? Because if any issue happed at one channel this should never affect the other channel since its an ASIL C Application. Or would this require two separate one channel switches being physically not in the same package?

 

Kind regards

    Hi Dierk,

    This device is not ASIL certified and is only FuSa capable.

    For a true ASIL-C system it is not recommended to use a two channel device. The customer must use two different devices to achieve this operation to confirm that if an issue arises with one path, it does not affect the other.

    Thanks,
