5 / 12 page 5 LT1313 PIN FUNCTIONS Supply Pins: Power is supplied to the device through the two supply pins which must be connected together at all times . The supply pins should be bypassed to ground if the device is more than six inches away from the main supply capacitor. A bypass capacitor in the range of 0.1 µF to 1 µF is sufficient. The supply voltage to the LT1313 can be loosely regulated between 13V and 20V. VPPOUT Pins: Each regulated output supplies power to the two PCMCIA card VPP pins which are typically tied to- gether at the socket. Each VPPOUT output is current limited to approximately 330mA. Thermal shutdown provides a second level of protection. A 1 µF to 10µF tantalum output capacitor is recommended. Input Enable Pins: The four digital input pins are high impedance inputs with approximately 20 µA input current at 2.4V. The input thresholds are compatible with CMOS controllers and can be driven from either 5V or 3.3V CMOS logic. ESD protection diodes limit input excursions to 0.6V below ground. VALID Output Pins: These pins are open-collector NPN outputs which are driven low when the corresponding VPPOUT pin is in regulation, i.e., when it is above 11V. Two external 51k pull-up resistors are connected between these outputs and the same 5V or 3.3V logic supply powering the PCMCIA compatible control logic. VCC Sense Pins: Two independent comparators and 4V references automatically switch the VPPOUT outputs from 5V to 3.3V depending upon the voltage sensed at the corresponding PCMCIA card socket VCC pin. The input current for these pins is approximately 30 µA. For 5V only operation, connect the Sense pins directly to ground. An ESD protection diode limits the input voltage to 0.6V below ground. Ground Pins: The two ground pins must be connected together at all times.
