Schematic Symbol and Pin Out Details
Pin No. Symbol Description and function
1 NC
No connection
This pin can be connected to GND
2 REF
Reference
This pin is connected to V
CC
via resistor, R
REF
. R
REF
should be selected to
source approximately 2.4mA into this pin. See Note 1
3 GATEL
Gate turn off
This pin sinks current, I
SINK
, from the OR’ing MOSFET Gate
4 GATEH
Gate turn on
This pin sources current, I
SOURCE
, to the OR’ing MOSFET Gate
5 V
CC
Power Supply
This is the supply pin. Decouple this point to ground with a ceramic capacitor
6 GND
Ground
This is the ground reference point. Connect to the OR’ing MOSFET Source terminal
7 BIAS
Bias
This pin is connected to V
CC
via R
BIAS
. R
BIAS
should be selected to source either 1 or
1.2 times I
REF
into this pin depending on the desired turn-off threshold voltage, V
T
.
See Note 1
8 DRAIN
Drain connection
This pin connects directly to the OR’ing MOSFET Drain terminal
Note 1- BIAS and REF pins should be assumed to be at GND+0.7V.
