PIU
ADIN:
ADC Input. A voltage between 0V and 2.56V applied
to this pin can be measured by the onboard ADC. Tie to
ground if unused.
ADR0 to ADR2:
Serial Bus Address Inputs. Tying these
pins to ground, open or INTV
CC
configures one of 27 pos-
sible addresses. See Table 1 in Applications Information.
ALERT:
Fault Alert Output. Open-drain logic output that
can be pulled to ground when a fault occurs to alert the
host controller. A fault alert is enabled by the ALERT
register. This device is compatible with SMBus alert
protocol. See Applications Information. Tie to ground if
unused.
BD_PRST:
Board Present Input. Ground this pin to enable
the N-channel FET to turn on after 100ms debounce delay.
When this pin is high, the FET is off. An internal 10
μ
A
current source pulls up this pin. Transitions on this pin will
be recorded in the FAULT register. A high-to-low transition
activates the logic to read the state of the ON pin and clear
Faults. See Applications Information.
Exposed Pad (Pin 33, UH Package):
Exposed Pad may be
left open or connected to device ground.
FB:
Foldback and Power Good Input. A resistive divider
from the output voltage is tied to this pin. When the voltage
at this pin drops below 3.41V, the output power is consid-
ered bad and the current limit is reduced. The power bad
condition can be indicated with the GPIO pin and a power
bad fault can be logged in this condition. See Applications
Information.
GATE:
Gate Drive for External N-Channel FET. An internal
18
μ
A current source charges the gate of the external
N-channel MOSFET. A resistor and capacitor network
from this pin to ground sets the turn-on rate and compen-
sates the active current limit. During turn-off there is a
1mA pull-down current. During a short circuit or under-
voltage lockout (V
DD
or INTV
CC
), a 600mA pull-down
current source between GATE and SOURCE is activated.
GND:
Device Ground.
