Pin No.
Name
Description and function
1 DNC
Do not connect
Leave pin floating.
2 REF
Reference
This pin is connected to V
CC
via resistor, R
REF.
Select R
REF
to source 2.16mA into this pin. Refer to Table
1, in Application Information section.
3 GATEL
Gate turn off
This pin sinks current, I
SINK
, from the synchronous MOSFET Gate.
4 GATEH
Gate turn on
This pin sources current, I
SOURCE
, to the synchronous MOSFET Gate.
5 V
CC
Power Supply
This is the supply pin. It is recommended to decouple this point to ground closely with a ceramic
capacitor.
6 GND
Ground
This is the ground reference point. Connect to the synchronous MOSFET Source terminal.
7 BIAS
Bias
This pin is connected to V
CC
via resistor, R
BIAS
.
Select R
BIAS
to source 3mA into this pin. Refer to Table 1,
in Application Information section.
8 DRAIN
Drain connection
This pin connects directly to the synchronous MOSFET Drain terminal.
