SENSE
13
I
A
Over-current sense.
The voltage on the SENSE input pin is used to detect over-current con-
ditions in the load connected to the external MOSFET. This pin is
directly connected to the source of the MOSFET, with an external
resistor (R
SENSE
) (typically a low resistance) connected between the
source of the MOSFET and V
NEG
.
GATE
14
O
A
MOSFET gate driver.
The GATE output pin attaches to the gate of the external MOSFET.
The voltage on the GATE pin is pulled to the voltage on the V
NEG
 pin
whenever the voltage on the UV
TH
 pin is less than the voltage on the
V
REFIN
 pin, or the voltage on the OV
TH
 pin is greater than the voltage
on the V
REFIN
 pin.
The GATE pin is also pulled to the voltage on the V
NEG
 pin when the
ENABLE input pin is low.
When current limit is reached, the voltage on the GATE pin is adjusted
to maintain a constant voltage across the R
SENSE
 resistor while the
C
TIMER
  capacitor starts to charge. When the voltage on C
TIMER
exceeds V
REFIN
/2, the GATE pin is pulled to V
NEG
 to turn off the exter-
nal MOSFET. A RC network can be added from the GATE pin to the
drain of the external MOSFET, along with a capacitor from the GATE
pin to the V
NEG
 pin, to control the slew rate of the GATE pin.
The GATE pin pull-up current is proportioned to the I
ISET
 current.
V
FB
15
I
A
External MOSFET drain monitor.
The V
FB
 input pin monitors the voltage at the drain of the external
power MOSFET switch with respect to the voltage on the V
NEG
 pin for
use by the internal foldback circuitry. An external resistor divider net-
work (R
FB1
 and R
FB2
) is attached between the drain of this external
MOSFET and the V
NEG
 pin (R
FB1
 is connected between the drain of
the external MOSFET and the V
FB
  pin, while R
FB2
  is connected
between the V
FB
 pin and the V
NEG
 pin). This prevents high-voltage
breakdown of the V
FB
 input.
DRAIN
TH
16
I
A
MOSFET drain comparator threshold.
This pin is used during the power-up sequence of the inserted board,
and after any fault condition that turns off the GATE pin drive. The
voltage on the pin indicates when the external FET is fully enhanced
by comparing the pin voltage to an internal reference voltage
(approximately 100 mV derived from the internal band gap reference).
An external resistor divider network (R
DRAIN1
 and R
DRAIN2
) is attached
between the drain of this external MOSFET and the V
NEG
 pin (R
DRAIN1
is connected between the drain of the external MOSFET and the
DRAIN
TH
 pin while R
DRAIN2
 is connected between the DRAIN
TH
 pin
and the V
NEG
 pin).
