Manufacturer:ALTERA Description:BT Current Source. Connect this pin to the gate of a suitable N-channel MOSFET for driving bus termination regulator output. BT Sense. Connect this pin to the bus termination regulator output. BT Current Sink. This pin is used to drive a N-channel MOSFET to sink the redundant current in the high-speed bus. Function Reserved. Pull up this pin to +5VSB through a 1.5 Kohm resistor. Power Ground. Connect this pin to ground. Power 5VSB . Input 5VSB supply. Charge Pump Cap. Attach flying capacitor between this pin and C2 to generate internally used high voltage from 5V power supply. Charge Pump Cap. Attach flying capacitor between this pin and C1 to generate internally used high voltage from 5V power supply. Charge Pump output. This pin produces voltage doubled 5V supply by charge pumping. Bypass with a 0.1uF capacitor. 5VDL Enable. Control 5VDL voltage output. Pull-up internally. Voltage Selection. Combine with VSET2 to select output voltages of STR regulators. Voltage Selection. Combine with VSET3 to select output voltages of STR regulators. S5 Signal. Control signal governing the soft off state S5. Pull-up internally. S3 Signal. Control signal governing the soft off state S3. Pull-up internally. 3VDL Sense. Connect this pin to the STR1 output. 3VDL Drive. Connect this pin to the gate of a suitable N-channel MOSFET for driving STR1 output. 5VSB Output Control. Connect this pin to the gate of a N-MOSFET to output 5VSB power to 5VDL. 3.3V/5V Output Control. Connect this pin to the gate of a N-MOSFET to output 3.3V/5V power to 3.3VDL/5VDL. Power OK. Open collector input/output. Used to indicate the ready of 5Vin supply. If any STR supply occurs over current and induce under-voltage, PWOK will be pull down. Soft-Start. Attach a capacitor (0.033u) to this pin to determine the softstart rate. A ramp generated by charging this capacitor with internal soft -start current (18uA) is used to clamp the voltage rising slew rate of STR regulators and 5VDL. Soft starting avoids too much rush current during voltage setup. STR1 Sense. Connect this pin to the STR1 output. STR1 Drive. Connect this pin to the gate of a suitable N-channel MOSFET for driving STR1 output. Pin Reserved |
