All Smart Card contacts are rated for 10kV ESD, eliminating the need for external ESD protection devices.Input voltage may range from 2.7V to 6.0V, allowing direct connection to a battery. Internal soft-start mitigates start-up problems that may result when the input power is provided by another regulator. Multiple devices may be paralleled and connected to a single controller for multicard applications.Battery life is maximized by 60μA operating current and 1μA shutdown current. The narrow SSOP packages minimize PCB area for compact portable systems.
