Lead Description
Logic and internal gate drive supply voltage. An internal zener clamp diode at 15.6 V norminal is included
to allow the V
CC
to be current fed directly from VIN typically by means of a high value resistor.
Oscillator timing resistor output; a resistor is connected from R
T
to C
T
. RT is out of phase with the half-
bridge output (VO).
Oscillator timing capacitor input; a capacitor is connected from C
T
to COM in order to program the
oscillator frequency according to the following equation:

PIN also invokes shutdown function (see note 2) where 75
is the effective impedence of the R
T
output stage.
High side gate drive floating supply. For bootstrap operation a high voltage fast recovery diode is needed
to feed from V
CC
to V
B
. (HD type circuits incorporate this diode).
