33993
FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
WAKE-UP (WAKE)
The WAKE pin is an open-drain output and a wake-up
input. The pin is designed to control a power supply Enable
pin. In the Normal mode, the WAKE pin is low. In the Sleep
mode, the WAKE pin is high. The WAKE pin has a pull-up to
the internal +5.0 V supply.
In Sleep mode with the WAKE pin high, falling edge of
WAKE will place the 33993 in Normal mode. In Sleep mode
with V
DD
applied, the INT pin 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 the WAKE
operation.
BATTERY INPUT (VPWR)
The V
PWR
pin is battery input and Power-ON Reset to the
33993 IC. The V
PWR
pin 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
pin.
VOLTAGE DRAIN SUPPLY (VDD)
The VDD input pin is used to determine logic levels on the
microprocessor interface (SPI) pins. Current from VDD is
used to drive SO output and the pull-up current for CS and
INT pins. V
DD
must be applied for wake-up from negative
edge of CS or INT.
GROUND (GND)
The GND pin provides ground for the IC as well as ground
for inputs programmed as switch-to-battery inputs.
PROGRAMMABLE SWITCHES 0–7 (SP0 – SP7)
The 33993 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 5
through
Table 10
in the
Logic
Commands and Registers
section of this datasheet. Voltages
greater than the V
PWR
supply voltage will source current
through the SP inputs to the V
PWR
pin. Transient battery
voltages greater than 40 V must be clamped by an external
device.
SWITCH-TO-GROUND INPUTS 0–13 (SG0 – SG13)
The SGn pins 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 5
through
Table 10
in the
Logic Commands and
Registers
section of this datasheet. Voltages greater than the
V
PWR
supply voltage will source current through the SG
inputs to the V
PWR
pin. Transient battery voltages greater
than 40 V must be clamped by an external device.
