Pin Description
(Refer to Figures 1 and 2)
Pin Number
Pin Name
Pin Function
1
Input
Resets current sense latch and turns on power MOSFET when taken above
threshold (3.5V typical). Pin 1 requires <1
μ
A to switch.
2
Threshold
Sets current sense trip voltage according to:
2200
R +1000
TRIP
V
=
where R
TH
to ground is 3.3k to 20k
. Adding capacitor C
TH
increases the
trip voltage at turn-on to 2V. Use C
TH
=10
μ
F for a 10ms turn-on time
constant.
3
Sense
The sense pin causes the current sense to trip when V
SENSE
is V
TRIP
above
V
SOURCE
. Pin 3 is used in conjunction with a current shunt in the source of
a 3 lead FET or a resistor R
S
in the sense lead of a current sensing FET.
Reference for the current sense voltage on pin 3 and return for the gate
clamp zener. Connect to the load side of current shunt or kelvin lead of
current sensing FET. Pins 3 and 4 can safely swing to
10V when turning
off inductive loads.
4
Source
5
Ground
6
Gate
Drives and clamps the gate of the power FET. Pin 6 will be clamped to
approximately
0.7V by an internal diode when turning off inductive loads.
7
V
+
Supply pin; must be decoupled to isolate from large transients caused by
the power FET drain. 10
μ
F is recommended close to pins 7 and 5.
8
Fault
Outputs status of protection circuit when pin 1 is high. Fault low indicates
normal operation; fault high indicates current sense tripped.
