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. 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.
