IRS2052MTRPBF

IRS2052MTRPBF is a 2-channel integrated analogue input class D audio amplifier driver with PWM modulators and protections. In conjunction with external MOSFET and external components, a complete 2 channel Class D audio amplifier can be realized. The IRS2052M is designed with floating analogue inputs and protection control interface pin especially for half bridge topology. High and low side MOSFET are protected from over current conditions by a programmable bi-directional current sensing. Essential elements of PWM modulator section allow flexible system design.

• Versatile protection control enabling latched, non-latched, or host controlled shutdown function
• Integrated clock oscillator, clipping detection
• External thermal sensor input, on-chip thermal shutdown with warning
• Programmable over current protection, programmable dead-time generation
• Start and stop click noise reduction, under voltage protection, high noise immunity
• High side floating supply offset voltage is 200V maximum
• Low side quiescent current is 5mA maximum at VDT=VCC
• UVCC hysteresis is 0.2V typical
• MLPQ 48 package
• Ambient temperature range from -40 to 125°C
