PIN
NAME
FUNCTION
C2
NC1
Normally Closed Terminal for USB Switch 1. NC1 is high impedance in shutdown.
C3
NC2
Normally Closed Terminal for USB Switch 2. NC2 is high impedance in shutdown.
Enable Input for LDO2. Drive ENLDO2 high to turn on the LDO2. Drive ENLDO2 low to turn off the LDO2.
C4
ENLDO2 LDO2 can also be enabled/disabled through the I²C interface. ENLDO2 and I²C control bit are logically
ORed. ENLDO2 has an internal 800kI pulldown resistor.
Enable Input for Load Switch. Drive ENLS high to turn on the load switch. Drive ENLS low to turn off the
C5
ENLS load switch. The load switch can also be enabled/disabled through the I²C interface. ENLS and I²C
control bit are logically ORed. ENLS has an internal 800kI pulldown resistor.
C6
BUCK Voltage Feedback for Step-Down Converter
200mA LDO5 Output. Bypass LDO5 to AGND with a 2.2FF ceramic capacitor. The output voltage of
D1
LDO5 LDO5 is programmable from 0.8V to 3.3V in 100mV steps. The output impedance of LDO5 is 300I when
disabled with the LDO5_ADEN bit set to 1.
D2
NO1
Normally Open Terminal for USB Switch 1. NO1 is high impedance in shutdown.
D3
NO2
Normally Open Terminal for USB Switch 2. NO2 is high impedance in shutdown.
Enable Input for LDO3. Drive ENLDO3 high to turn on the LDO3. Drive ENLDO3 low to turn off the LDO3.
D4
ENLDO3 LDO3 can also be enabled/disabled through the I²C interface. ENLDO3 and I²C control bit are logically
ORed. ENLDO3 has an internal 800kI pulldown resistor.
Enable Input for LDO4 and LDO5. Drive ENLDO45 high to turn on the LDO4 and LDO5. Drive ENLDO45
D5
ENLDO45
low to turn off the LDO4 and LDO5. LDO4 and LDO5 can also be enabled/disabled individually through
the I²C interface. ENLDO45 and I²C control bits (ELDO4 and ELDO5) are logically ORed. ENLDO45 has
an internal 800kI pulldown resistor.
D6
SCL
I²C-Compatible Serial Interface Clock High-Impedance Input
150mA LDO4 Output. Bypass LDO4 to GND with a 1FF ceramic capacitor. The output voltage of LDO4
E1
LDO4 is programmable from 0.8V to 3.3V in 100mV steps. The output impedance of LDO4 is 300I when
disabled with the LDO4_ADEN bit set to 1.
E2
COM1 Common Terminal for USB High Switch 1
E3
COM2 Common Terminal for USB High Switch 2
E4
AGND Analog Ground. Ground for all the LDOs, control section, and USB switches.
E5
LS
Load Switch Output. LS is connected to the drain of an internal p-channel MOSFET. VLS = VBUCK -
RDS(ON) (p-channel MOSFET) x load current.
E6
SDA
