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.
