Description
The IRS20965S is a high voltage, high speed MOSFET driver with floating PWM inputs designed for Class D
audio amplifier applications.
Bi-directional current sensing using RDS(ON) of the MOSFETs detects over current conditions during positive and
negative load currents without any external shunt resistors. An over current flag output provides over current
status without shutting down, enabling full external control over OCP protection sequences.
Independent HIN and LIN inputs offers independent control on HO and LO. Internal shoot-thru prevention logic
provides safe operation by eliminating simultaneous ON state in the output MOSFET.

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to VSS; all currents are defined positive into any lead. The Thermal
Resistance and Power Dissipation ratings are measured under board mounted and still air conditions.
