Functional Descriptions
IRS2093 Gate Driver IC
The IRAUDAMP8 uses the IRS2093, a 4 Channel high-voltage (up to 200 V), high-speed power
MOSFET driver with internal dead-time and protection functions specifically designed for Class D
audio amplifier applications. These functions include OCP and UVP. The IRS2093 integrates bi-
directional over current protection for both high-side and low-side MOSFETs. The dead-time can
be selected for optimized performance according to the size of the MOSFET, minimizing dead-
time while preventing shoot-through. As a result, there is no gate-timing adjustment required
externally. Selectable dead-time through the DT pin voltage is an easy and reliable function which
requires only two external resistors, R12 and R13 as shown on Fig 16 or Fig 22 below.
The IRS2093 offers the following functions.
Refer to IRS2093 datasheet and AN-1146 for more details.
