73S8009C  
Versatile Power Management  
and Smart Card Interface IC  
DATA SHEET  
January 2010  
Simplifying System Integration™  
DS_8009C_025  
When power is supplied by VPC or VBAT, the  
73S8009C is controlled by the ON_OFF pin in the  
manner of a “push-on/push-off” button action. The  
signals OFF_REQ and OFF_ACK 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.  
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).  
When power is supplied via the VBUS 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 VBUS power when VCC is off is  
less than 500 µA to conform to USB “SUSPEND”  
requirements.  
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  
APPLICATIONS  
Handheld PINpad smart card readers for  
e-commerce, secure login, e-health, Gov’t ID  
and loyalty  
level-shifted to the selected VCC 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 VCC rises) and power-down.  
The 73S8009C contains two handshaking signals  
for the controller: OFF indicates that a card is  
present, and RDY indicates that VCC is at an  
acceptable value. The 73S8009C will perform  
emergency deactivation upon card removal,  
voltage faults, or over-current events  
Point of Sales & Transaction Terminals  
General Purpose Smart Card Readers  
ADVANTAGES  
Ideally suited to USB bus-powered  
applications  
Ideal for combo bus-powered and/or  
self-powered systems  
Automatic battery switchover in bus  
powered systems  
The power management circuitry of the 73S8009C  
allows operation from a wide range of voltages  
from multiple sources. VPC is converted by using  
an inductive, step-up power converter to the  
intermediate voltage, VP. VP is used by linear  
voltage regulators and switches to create the  
voltages VDD and as required, VCC. VDD is used by  
the 73S8009C and is also made available for the  
companion controller circuit or other external  
circuits. The two pins, VBAT and VBUS 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  
VBAT or VBUS to be connected to VPC. When the  
voltage on VBUS is zero, VBAT is connected to VPC.  
When voltage is applied to VBUS, the switch will  
select VBUS as the source for power.  
Very low-power mode (sub-µA) with  
push-button ON/OFF switch input with  
de-bounce  
Provides 3.3 V / 40 mA power to external  
circuitry (host processor or peripheral circuits)  
The inductor-based DC-DC converter provides  
higher current and efficiency than usual  
charge-pump capacitor-based converters:  
Ideal for battery-powered applications
