73S8009C
Versatile Power Management
and Smart Card Interface IC
Simplifying System Integration?
DS_8009C_025
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

When power is supplied by V PC or V BAT , the
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 μ A.
When power is supplied via the V BUS pin, the
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 BUS power when V CC is off is
less than 500 μ A to conform to USB “SUSPEND”
requirements.
APPLICATIONS
level-shifted to the selected V CC value. Although
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 CC rises) and power-down.
The 73S8009C contains two handshaking signals

present, and RDY indicates that V CC is at an
acceptable value. The 73S8009C will perform
emergency deactivation upon card removal,
voltage faults, or over-current events
The power management circuitry of the 73S8009C
allows operation from a wide range of voltages
from multiple sources. V PC is converted by using
an inductive, step-up power converter to the
intermediate voltage, V P . V P is used by linear
voltage regulators and switches to create the
voltages V DD and as required, V CC . V DD is used by
the 73S8009C and is also made available for the
companion controller circuit or other external
circuits. The V BAT and V BUS pins provide inputs
from alternate power sources as required. An
internal switch in the 73S8009C acts as a
single-pole, double-throw switch that selects either
V BAT or V BUS to be connected to V PC . When the
voltage on V BUS is zero, V BAT is connected to V PC .
When voltage is applied to V BUS , the switch selects
V BUS as the source for power.
