Figure 45. Operating Chronograms in Case of Overvoltage
The following equations show how to calculate the
brownout resistors.
First of all, select the bulk voltage value at which the
controller must start switching (V bulk(on) ) and the bulk
R bol +
V BO V bulk ( on ) * V bulk off
I BO V bulk ( on ) * V BO
(eq. 9)
voltage for shutdown (V bulk(off) ). Then use the following
equation to calculate R bou and R bol .
R bou +
R bol V bulk ( on ) * V BO
