FIGURE 12. UVLO/OVP Divider
The impedance seen looking into the resistor divider from the
UVLO and OVP pins determines the hysteresis level. UVLO
and OVP enable and disable thresholds are calculated using
the equations in the table below for the three-resistor divider
illustrated in Figure 12.
TABLE 1. UVO/OVP Divider Formulas
Outputs disabled due to VIN falling below UVLO threshold
Outputs enabled due to VIN rising above UVLO threshold
UVLO
on = UVLOoff + (23 µA x R1)
Outputs disabled due to VIN rising above OVP threshold
Outputs enabled due to VIN falling below OVP threshold
OVP
on = OVPoff - [23 µA x (R1 + R2)]
The typical operating ranges of undervoltage and overvoltage
thresholds are calculated from the above equations. For ex-
ample, for resistor values R1 = 86.6k
Ω, R2 = 2.10kΩ and R3
= 1.40k
Ω the computed thresholds are:
UVLO turn-off = 32.2V
UVLO turn-on = 34.2V
OVP turn-on = 78.4V
OVP turn-off = 80.5V
