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:
f =
1
1 . 4 × ( R T + 75 ? ) × C T
C T 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).
