PRODUCTION DATA
The UVLO resistors RUV1 and RUV2 set the UVLO threshold and hysteresis according to the relationship shown in Equation 18 and Equation 19.
where
Setting UVLO hysteresis of 2.5 V and UVLO rising threshold of 12 V results in RUV1 = 14.53 kΩ and
RUV2 = 125 kΩ. Selecting standard values of RUV1 = R7 = 14 kΩ and RUV2 = R5 = 127 kΩ results in UVLO threshold and hysteresis of 12.4 V and 2.5 V, respectively.
