Low Voltage Monitoring Function
The system contains a circuit to send a control signal to the microcomputer when the output voltage drops.
The circuit includes the following features.
Two-point monitoring of output voltage (V
NMI
and V
STBY
)
Availability of fine adjustment of Vth1 (V
NMI
) and Vth2 (V
STBY
)
Output of control signal in standby mode of microcomputer
Figure 5 shows the timing chart of control signals when the output voltage drops.
If the output voltage drops below Vth1 (4.60 V), the
NMI
signal rises to request the microcomputer to issue
the
NMI
interrupt signal. The
RES
signal falls t
RES
seconds after the
NMI
signal rises. If the output voltage
drops further to below Vth2 (3.2 V), the
STBY
signal rises to enable the micro-computer to enter standby
mode.
