Hi.
Could somebody help me to have sure that I have made the correct calculations for the resistors of the UVLO of LMR14050? Its on page 10 and 11 of the datasheet.
Vstop = 8V
Vstart = 9.4V
Ihys = 3.6uA
Ien = 1uA
Ven = 1.2V
RenT = (Vstart-Vstop) / Ihys
RenT = ( (9.4-8) / (3.6*10^-6) )
RenT = 388.8K ohms = 390K ohms 1%
RenB = ( Ven / ( ( (Vstart-Ven) / RenT ) + Ien ) )
RenB = ( 1.2 / ( ( (9.4-1.2) / (390*10^3) ) + (1*10^-6) ) )
RenB = 54.48K ohms = 56K ohms 1%
390K and 56K make sense?
Regards.
