T (Pin 1/Pin 1):
Reset or Power-Good Output. Open
drain output that pulls low if the FB pin voltage falls below
its threshold (0.6V). If an undervoltage lockout condition
occurs, the
R
E
S
E
T pin pulls low and ignores the FB pin
voltage.
ON (Pin 2/Pin 2):
ON Control Input. A rising edge above
the ON pin threshold (0.8V) initiates the start-up cycle and
turns on the external N-channel MOSFET. A falling edge
below 0.72V (80mV ON pin hysteresis) turns it off. If this
pin is pulled below 0.4V, following a circuit breaker trip, it
resets the electronic circuit breaker and fault latch.
FILTER (Pin 3/Pin 3):
Fault Filter Input. Connect a capacitor
between this pin and ground to set up the fault filter delay.
This pin sources 60μA or sinks 2.4μA when the voltage
across the sense resistor exceeds 25mV or drops below
25mV respectively.
TIMER (Pin 4/Pin 4):
Timer Input. Connect a capacitor
between this pin and ground to set up the start-up timing
cycle duration. It also defines the
R
E
S
E
T power-good delay
from the instant the FB pin voltage exceeds 0.6V. This pin
sources 2μA pull-up current during ramp up.
SS (Pin 5/Not Available):
Soft-Start Control Input. Con-
nect a capacitor between this pin and ground for soft-start
during power-up. It controls the GATE ramp up, limiting
the rate of change of the inrush current when the external
MOSFET turns on. If soft-start function is not used, leave
this pin unconnected.
GND (Pin 6/Pin 5):
Device Ground.
FB (Pin 7/Pin 6):
Output Monitor for Reset Output. A resis-
tive divider from the external MOSFET’s source terminal is
tied to this pin. When the voltage at this pin drops below
0.6V, the
R
E
S
E
T pin pulls low.
GATE (Pin 8/Pin 7):
Gate Drive for External N-Channel
MOSFET. An internal charge pump provides 20μA gate
pull-up current and sufficient gate overdrive to the exter-
nal MOSFET. An internal shunt regulator limits the GATE
pin voltage to about 6.2V (typ) above the SENSEN pin
voltage.
SENSEN (Pin 9/Pin 8):
Circuit Breaker Negative Sense
Input. Connect this pin to the sense resistor terminal wired
to the drain of the external N-channel MOSFET. The sense
resistor is placed in the power path between SENSEP and
SENSEN pins to sense the output current. The electronic
circuit breaker trips if the voltage across the sense resistor
exceeds 25mV for more than a fault filter delay.
SENSEP (Pin 10/Pin 9):
Circuit Breaker Positive Sense
Input. Connect this pin to the sense resistor terminal wired
to the positive supply input for the external output load.
This positive supply range extends from 0V to 6V.
V
CC
(Pin 11/Pin 10):
Bias Supply Input. Operates from
2.3V to 6V. An internal undervoltage lockout circuit disables
the device until the input supply voltage at V
CC
exceeds
2.12V typically.
F
A
U
L
T (Pin 12/Not Available):
Fault Input and Output. As
an input, driving this pin low (<1.253V) will latch-off the
device to fault mode. As an output, it is either pulled high
by an internal 5μA pull-up or an external pull-up resistor
to positive supply under normal operating condition. It
pulls low when the circuit breaker is tripped due to an
overcurrent fault.
Exposed Pad (Pin 13/Not Available):
Exposed pad may
be left open or connected to device ground.
