FUNCTION
Reserved 1 Pin Reserved
BTDRV
2
BT Current Source. Connect this pin to the gate of a suitable N-channel
MOSFET for driving bus termination regulator output.
BTSEN
BTSINK
3 BT Sense. Connect this pin to the bus termination regulator output.
4
BT Current Sink. This pin is used to drive a N-channel MOSFET to sink the
redundant current in the high-speed bus.
Reserved 5 Function Reserved. Pull up this pin to +5VSB through a 1.5 Kohm resistor.
Vss 6 Power Ground. Connect this pin to ground.
5VSB
C1
7 Power 5VSB. Input 5VSB supply.
8
Charge Pump Cap. Attach flying capacitor between this pin and C2 to
generate internally used high voltage from 5V power supply.
C2
9
Charge Pump Cap. Attach flying capacitor between this pin and C1 to
generate internally used high voltage from 5V power supply.
ChrPmp
10
Charge Pump output. This pin produces voltage doubled 5V supply by
charge pumping. Bypass with a 0.1uF capacitor.
5VDLEN#
VSET3
11 5VDL Enable. Control 5VDL voltage output. Pull-up internally.
12
Voltage Selection. Combine with VSET2 to select output voltages of STR
regulators.
VSET2
13
Voltage Selection. Combine with VSET3 to select output voltages of STR
regulators.
S5#
14 S5 Signal. Control signal governing the soft off state S5. Pull-up internally.
S3#
15 S3 Signal. Control signal governing the soft off state S3. Pull-up internally.
3VSBSEN
3VDLSB
16 3VDL Sense. Connect this pin to the STR1 output.
17
3VDL Drive. Connect this pin to the gate of a suitable N-channel MOSFET for
driving STR1 output.
5VDLSB
18
5VSB Output Control. Connect this pin to the gate of a N-MOSFET to output
5VSB power to 5VDL.
3VDRV/5VDRV
19
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
PWOK
20 supply. If any STR supply occurs over current and induce under-voltage,
PWOK will be pull down.
SS
STR1SEN
STR1DRV
Soft-Start. Attach a capacitor (0.033u) to this pin to determine the softstart
21
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.
22 STR1 Sense. Connect this pin to the STR1 output.
23
STR1 Drive. Connect this pin to the gate of a suitable N-channel MOSFET for
driving STR1 output.
