PIN DESCRIPTIONS
The descriptions of the pins are listed in
Table 3-1
.
TABLE 3-1:
PIN FUNCTION TABLE
3.1
Ground Terminal (GND)
GND provides the negative reference for the analog
input voltage. Typically, the circuit ground is used.
3.2
Reset Output (RESET) (TC1270)
RESET output remains low while V
CC
is below the
Reset voltage threshold (V
TRIP
). Once the device
voltage (V
CC
) returns to a high level (V
TRIP
+ V
HYS
), the
device will remain in Reset for the Reset delay timer
(T
RST
). After that time expires, the RESET pin will be
driven to the high state.
3.3
Reset Output (RESET) (TC1271)
RESET output remains high while V
CC
is below the
Reset voltage threshold (V
TRIP
). Once the device
voltage (V
CC
) returns to a high level (V
TRIP
+ V
HYS
), the
device will remain in Reset for the Reset delay timer
(T
RST
). After that time expires, the RESET pin will be
driven to the low state.
3.4
Manual Reset (MR)
The Manual Reset (MR) input pin allows a push button
switch to easily be connected to the system. When the
push button is depressed, it forces a system Reset.
This pin has circuitry that filters noise that may be
present on the MR signal.
The MR pin is active-low and has an internal pull-up
resistor.
3.5
Supply Voltage (V
CC
)
V
CC
can be used for power supply monitoring or a
voltage level that requires monitoring.
Pin No.
