3.1
Ground Terminal (V
SS
)
V
SS
provides the negative reference for the analog
input voltage. Typically, the circuit ground is used.
3.2
Supply Voltage (V
DD
)
V
DD
can be used for power supply monitoring or a
voltage level that requires monitoring.
3.3
Reset Output (RST and RST)
There are three types of Reset output pins. These are:
1.
Push-Pull active-low Reset
2.
Push-Pull active-high Reset
3.
Open-Drain active-low Reset, External pull-up
resistor required.
3.3.1
ACTIVE-LOW (RST) - PUSH-PULL
The RST push-pull output remains low while V
DD
is
below the reset voltage threshold (V
TRIP
). The time that
the RST pin is held low after the device voltage (V
DD
)
returns to a high level (> V
TRIP
) is typically 280 ms.
After the Reset delay timer expires, the RST pin will be
driven to the high state.
3.3.2
ACTIVE-HIGH (RST) - PUSH-PULL
The RST push-pull output remains high while V
DD
is
below the reset voltage threshold (V
TRIP
). The time that
the RST pin is held high after the device voltage (V
DD
)
returns to a high level (> V
TRIP
) is typically 280 ms.
After the Reset delay timer expires, the RST pin will be
driven to the low state.
3.3.3
ACTIVE-LOW (RST) - OPEN-DRAIN
The RST open-drain output remains low while V
DD
is
below the reset voltage threshold (V
TRIP
). The time that
the RST pin is held low after the device voltage (V
DD
)
returns to a high level (> V
TRIP
) depends on the Reset
Timeout selected. After the Reset Delay Timer expires,
the RST pin will float.
3.4
Manual Reset Input (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.
