APPLICATIONS INFORMATION
Pin 2 (V
IN1
) acts as both the input to Voltage Detector
#1, as well as the power supply input for the chip. As
such, always assign V
IN1
to monitor voltages between
1.5V and 10V. Failure to do this will result in unreliable
detector operation due to an out-of-tolerance supply
voltage. In high noise environments, it may be
necessary to install a small input bypass capacitor
(0.01
μ
F to 0.1
μ
F) from V
IN1
to ground to minimize on-
chip power supply noise.

Battery and Main Supply Monitor
The circuit shown in Figure 4-1 provides both a
processor supply monitor/reset function, as well as a
low
battery
detect
function.
TC52N3330ECT (N-Channel outputs) uses Detector 2
to monitor the system power supply rail. When the
power supply is 10% below its nominal output voltage
rating, the V
OUT2
output is driven and held low. When
the power supply voltage is above 3.0V nominal, V
OUT2
is driven to an open circuit and the combination of R
1
and C
1
provides a reset time out delay. Detector 1
monitors the voltage on the main supply battery. A low
battery condition is indicated when the battery voltage
falls to 3.3V, at which time the main processor is
interrupted to initiate a warning or system shutdown.
