TDA 4814
1)
VS ON means that VSH has been exceeded but that the voltage is still greater than (VSH – VS hy).
2) Calculation of the output voltage
VQM : VQM = C x VM1* x VM2* in V.
3) Step functions at comparator input
V
COMP = – 100 mV
V
COMP = + 100 mV.
Detector (I DET)
Upper switching voltage
for voltage rising (H)
Lower switching voltage
for voltage falling (L)
