... U PIN FUNCTIONS LTC1470 OUT (Pins 1, 8): Output Pins. The outputs of the LTC1470 are switched between three operating states: OFF, 3.3V and 5V. These pins are protected against accidental short circuits to ground by SafeSlot current limit circuitry which protects the socket, the card, and the system power supplies against damage ...

... LTC1470/LTC1471 U OPERATION The LTC1470 (or 1/2 of the LTC1471) consists of the following functional blocks: Input TTL/CMOS Converters The enable inputs are designed to accommodate a wide range of 3V and 5V logic families. The input threshold voltage is approximately 1.4V with approximately 100mV of hysteresis. The inputs enable the bias generator, the gate charge pumps and the protection circuity which are powered from the 5V supply ...

... NMOS switch gates Hi-Z are fully discharged to 0V. Whenever possible, however best to leave the 5V LTC1470/LTC1471 quiescent current drops to <1 A with all the switches turned off and therefore no 5V power is consumed in the standby mode. LTC1470/LTC1471 supply pins (see graphs in Typical Perfor- IN pin(s) continuously powered ...

... VPP power. And, because the LTC1470/LTC1471 do not require 12V power to operate (only 5V), the 12V VPP regulation and switching may be operated separately from the 3.3V/5V V switching. This increases system configuration flexibility and reduces total system cost by eliminating the need for a third regulator for 12V power ...
