Other Parts Discussed in Thread: LMV7231, TPS3306-Q1, TPS386000-Q1, TPS3106-EP

Hi My customer is asking for voltage supervision proposal per below. Do we have anything available or in development for 6 channels? If not what´s our best solution , I understand this is not a lot of data but perhaps you can give some guidance? 

 

Do you have any Voltage Supervisor chip to recommend?

Can monitor 6 different voltages: Max 3.3V and Min ~0.7V. Prefer adjustable input voltage, not fixed voltage.

Individual/independent output Power Good signal for every monitored voltage.

temp range -40-+105C

    Par,

    I think the best solution is LMV7231 which is 6-channel device with adjustable inputs that feature under and over voltage detection.

    Other solutions might include using multiple devices from these options:

    We have a 4-channel supervisor TPS386000-Q1 with adjustable inputs and programmable delays. Very versatile device. We also have 3-channel device TPS3306-Q1 but 2 of the channels (SENSE1 and SENSE2) are fixed while PFI is adjustable. We also have 2-channel device TPS3106-EP with 1 channel fixed (VDD) and 1 channel adjustable (SENSE).

    Please let me know if these will work for your application or if you have any additional questions. Thanks!

    -Michael
