Figure 12. Undervoltage Lockout Model
VCEsat is the saturation voltage of the comparator output transistor.
The comparator trip point voltage can be calculated with Equation 21.
Equation 21.
If power to the mobile module is to be held off until V_DC exceeds 7.5V, Equation 21 can be
rearranged to solve for R18.
Equation 22.
A value for R18 can be determined by plugging these values into Equation 23.
Equation 23.
R18 = 11.0 k
(4.99 k
is a standard 1% resistor value, which would provide lockout below 7.532V.)
5.3.4.7
Overvoltage Lockout
The mobile module operates with a maximum input voltage of 21.0V. This circuit can be set to lock
out the input voltage if it exceeds the desired input.
