D6 and C5 form a bootstrap supply that provides a floating voltage to the HO gate driver. The VAA and VSS input supplies are derived from +B and -B via R52 and C18, and R50 and C12, respectively. Thus, a fully functional Class D PWM amplifier plus driver circuit is realized in an SO16 package with just a few small components. + - . . . R13 IN- COMP C23 .

These functions include OCP and UVP. Bi- directional current protection for both the high-side and low-side MOSFETs are internal to the IRS2092S, and the trip levels for both MOSFETs can be set independently. In this design, the dead time can be selected for optimized performance by minimizing dead time while preventing shoot-through. As a result, there is no gate-timing adjustment on the board. Selectable dead time through the DT pin voltage is an easy and reliable function which requires only two external resistors, R11 and R9 as shown on Fig11 below. |
