73S8009C

Versatile Power Management

and Smart Card Interface IC

DATA SHEET

January 2010

Simplifying System Integration™

DS_8009C_025

When power is supplied by V_PCor V_BAT, 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 V_BUSpin, 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_BUSpower when V_CCis 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

and loyalty

level-shifted to the selected V_CCvalue. 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_CCrises) and power-down.

The 73S8009C contains two handshaking signals

for the controller: OFF indicates that a card is

present, and RDY indicates that V_CCis at an

acceptable value. The 73S8009C will perform

emergency deactivation upon card removal,

voltage faults, or over-current events

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. V_PCis converted by using

an inductive, step-up power converter to the

intermediate voltage, V_P. V_Pis used by linear

voltage regulators and switches to create the

voltages V_DDand as required, V_CC. V_DDis used by

the 73S8009C and is also made available for the

companion controller circuit or other external

circuits. The two pins, V_BATand V_BUSprovide

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_BATor V_BUSto be connected to V_PC. When the

voltage on V_BUSis zero, V_BATis connected to V_PC.

When voltage is applied to V_BUS, the switch will

select V_BUSas the source for power.

Very low-power mode (sub-µA) with

push-button ON/OFF switch input with

•

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
