IRS2052MPbF
2 CH Digital Audio Amplifier
Features
• 2 channel integrated analog input Class D
audio amplifier driver
• 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
Note
The IRS2052M digital audio driver is a two
channel version of IRS2092(S) with additional
features, such as internal clock and over
temperature protection. The IRS2052M
features clipping detection outputs, on-chip
over temperature detection, over temperature
sensor inputs and a fault reporting output.

IN-1 and IN-2 contain clamping diode to GND.
VAA-VSS, VCC-COM, VCC2-COM2, VB1-VS1 and VB2-VS2 contain internal shunt zener
diodes. Note that the voltage ratings of these can be limited by the clamping current.
For the rising and falling edges of step signal of 10V. VSS=15V to 200V.
According to JESD51-5. JEDEC still air chamber.
