Short Circuit Protection function when GND and is short, ERRI become LOW and ERRO HIGH and it makes capacitor
charging. fanally AMP3 is OFF.(figure 5)
Figure 3. DC/DC Converter Control Circuit
Switching off time depen on a capacitor of the SCP . and the equation is as follow.
V
I
SCP
Max Duty can be controlled resistor. the equation is as follow
.
Capacitor of the SCP terminal can control disable switiching time and it can be calculated by as follow equation.
Over Voltage Protection BATT Voltage is over 9.7V charging SCP terminal Capacitor, it reach to V
TH
SW terminal signal
is OFF the equation is as follow
If Output Voltage of RSTOUT Circuit DC/DC Conver is over than 90%, RSTOUT terminal turn to HIGH and Hysteresis is
50mV. and RSTOUT stste is ON.
