Description
Power control pin. Connected to normally open SPST
switch to ground. Closing switch for duration greater
than de-bounce period will turn 73S8009C circuit “on.”
If 73S8009C is “on,” closing switch will turn 73S8009C
to “off” state after the de-bounce period and
OFF_REQ/OFF_ACK handshake.
OFF_REQ
11
O
Digital output. Request to the host system controller to
turn the 73S8009C off. If ON_OFF switch is closed (to
ground) for de-bounce duration and circuit is “on,”
OFF_REQ will go high (Request to turn OFF).
Connected to OFF_ACK via 100 k ? internal resistor.
OFF_ACK
9
I
Setting OFF_ACK high will power “off” all analog
functions and disconnect the 73S8009C from V BAT or
V PC . The pin has an internal 100 k ? resistor
connection to OFF_REQ so that when not connected or
no host interaction is required, the Acknowledge will be
true and the circuit will turn “off” immediately with
OFF_REQ.
