73S8009C Versatile Power Management and Smart Card Interface IC

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.

73S8009C Versatile Power Management and Smart Card Interface IC Simplifying System Integration™ DS_8009C_025 www.DataSheet4U.com DATA SHEET February 2010 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 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.
