IRS2452AM

IRS2452AM is a two channel, high voltage, high performance Class D audio amplifier driver with PWM modulators and protections. In conjunction with external MOSFET, the IRS2452AM forms a complete 2 channel Class D audio amplifier. The IRS2452AM is designed with floating analogue inputs and protection control interface pins convenient for half bridge applications. High and low side MOSFET are protected from over current conditions by a programmable over current protection. Essential elements of PWM modulator section allow flexible system design.

• Differential or single-ended input
• Versatile protection control enabling latched, nonlatched, or host controlled shutdown function
• Programmable over current protection, programmable dead-time generation
• External thermal sensor input, click noise reduction
• Under voltage protection, high noise immunity
• High side floating supply offset voltage is 400V maximum
• Switching frequency is 800KHz typical
• UVCC hysteresis is 0.2V typical
• MLPQ 32 package
• Ambient temperature range from -40 to 125°C
