Hi team,
May you help me understand what's the main difference between TLV840-Q1 and TPS3840-Q1?
Why TLV840-Q1 is cheaper, and in what kind of situation TPS3840-Q1 is required?
Thanks.

    Hi Nai-Wen,

    The main difference is that TLV840-Q1 has a input voltage range of 0.7V to 6V while the TPS3840-Q1 has voltage range of 1.6V to 10V.

    Both perform the same function of under voltage monitoring but the TPS3840-Q1 should be considered if the Supervisor needs to be connected to a higher voltage source.

    Hope this is clear.

    Thanks,

    Isa
