Hi Guys,
I am thinking how to better realize disabling power of circuit in undervoltage situations.
Many DCDC converters have UVLO at about 2.8V that could be suitable for 1 cell battery, but I am designing 12V battery powered circuit.
Some DCDC also have adjustable UVLO, but because I need to use large resistors for UVLO voltage divider so that I don't drain battery more I am will get too large hysteresis voltage Uhyst=Rlarge*Ihyst
Can you recommend the best way of realizing undervoltage lockout with low power consumption?
