DESCRIPTION
The Teridian 73S8009C is a versatile power
management and single smart card interface circuit
that is ideally suited for smart card reader products
that are battery and/or USB bus-powered. In
addition to its EMV 4.1 and ISO-7816-3 compliant
smart card-to-host interface circuitry; it provides
control, conversion, and regulation of power for a
companion host processor circuit and power for the
smart card. The 73S8009C can operate from a
single 2.7 V to 6.5 V source supply, or a
combination of battery power (4.0 V to 6.5 V) and
USB power (4.4 V to 5.5 V).
The 73S8009C supports 5 V, 3 V, and 1.8 V smart
cards. The smart card signals for RST, CLK, IO,
and auxiliary signals AUX1 and AUX2 are
level-shifted to the selected V
the host controller is required to handle the
detailed signal timing for activation and de-
activation under normal conditions, the 73S8009C
blocks any spurious signals on CLK, RST and IO
during power-up (as V
The 73S8009C contains two handshaking signals
for the controller: OFF indicates that a card is
present, and RDY indicates that V

emergency deactivation upon card removal,

When power is supplied by V
73S8009C is controlled by the ON_OFF pin in the
manner of a “push-on/push-off” button action. The
OFF_REQ and OFF_ACK signals provide
handshaking and control of the power “off”
function by the controller. A SPST momentary
switch to ground connected to ON_OFF is all that
is required for power control. Alternatively, the
“off” state can be initiated from the host controller
through OFF_ACK. When the 73S8009C is “off,”
the current is less than 1 µA.
When power is supplied via the V
73S8009C is unconditionally in the “power-on”
state regardless of the action of the ON/OFF
switch or OFF_ACK signal. Power supply current
operating from the V
less than 500 µA to conform to USB “SUSPEND”
requirements.
