MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
WAKE
The
WAKE
terminal is an open-drain output and a wake-up
input. The terminal is designed to control a power supply
Enable terminal. In the Normal mode, the
WAKE
terminal is
LOW. In the Sleep mode, the
WAKE
terminal is HIGH. The
WAKE
terminal has a pullup to the internal +5.0 V supply.
In Sleep mode with the
WAKE
terminal HIGH, falling edge of
WAKE
will place the 33972 in Normal mode. In Sleep mode with
V
DD
applied, the
INT
terminal must be HIGH for negative edge
of
WAKE
to wake up the device. If V
DD
is not applied to the
device in Sleep mode,
INT
does not affect
WAKE
operation.
V
PWR
The V
PWR
terminal is battery input and Power-ON Reset to
the 33972 IC. The V
PWR
terminal requires external reverse
battery and transient protection. Maximum input voltage on
V
PWR
is 50 V. All wetting, sustain, and internal logic current is
provided from the V
PWR
terminal.
V
DD
The V
DD
input terminal is used to determine logic levels on
the microprocessor interface (SPI) terminals. Current from V
DD
is used to drive SO output and the pullup current for
CS
and
INT
terminals. V
DD
must be applied for wake-up from negative edge
of
CS
or
INT
.
GND
The GND terminal provides ground for the IC as well as
ground for inputs programmed as switch-to-battery inputs.
SP0:SP7
The 33972 device has 8 switch inputs capable of being
programmed to read switch-to-ground or switch-to-battery
contacts. The input is compared with a 4.0 V reference. When
programmed to be switch-to-battery, voltages greater than
4.0 V are considered closed. Voltages less than 4.0 V are
considered open. The opposite holds true when inputs are
programmed as switch-to-ground. Programming features are
defined in
Table 1
through
Table 6
in the
Device Operation
section of this datasheet beginning on page 12. Voltages
greater than the V
PWR
supply voltage will source current
through the SP inputs to the V
PWR
terminal. Transient battery
voltages greater than 40 V must be clamped by an external
device.
SG0:SG13
The SGn terminals are switch-to-ground inputs only. The
input is compared with a 4.0 V reference. Voltages greater than
4.0 V are considered open. Voltages less than 4.0 V are
considered closed. Programming features are defined in
Table 1
through
Table 6
in the
Device Operation
section of this
datasheet beginning on page 12. Voltages greater than the
V
PWR
supply voltage will source current through the SG inputs
to the V
PWR
terminal. Transient battery voltages greater than
40 V must be clamped by an external device.
