S
The switching node common to the high and low−side FETs. The high−side (TG) driv-
er and supply (BST) are referenced to this pin.
Driver output to the high−side MOSFET gate.
Bootstrap supply voltage input. In conjunction with a Schottky diode to V
1.0 mF ceramic capacitor connected between BST and DRN develops supply voltage
for the high−side driver (TG).
Logic level control input produces complementary output states − no inversion at TG;
inversion at BG.
Not Connected.
Logic level enable input forces TG and BG low, and supply current to 10 mA when
EN is low.
Power supply input. A 0.1 mF to 1.0 mF ceramic capacitor should be connected from
this pin to PGND.
Driver output to the low−side (synchronous rectifier) MOSFET gate.
Ground.
