The BD28623MUV-E2: The BD28623MUV-: The ROHM BD28623MUV- is a Class D stereo audio amplifier IC delivering 17W per channel into an 8Ω load from a supply rail between 8.5V and 24V. The Class D switching topology keeps quiescent dissipation low, so the supply current at idle is a fraction of what a linear AB amplifier would pull at the same rail voltage.
Depop and short-circuit protection — two features that save a board spin
The BD28623MUV- includes depop circuitry to suppress the turn-on/turn-off pop through the speakers, and short-circuit protection on the output stage. Depop means you can tie the shutdown pin to a GPIO without needing an external mute relay or series resistor — the ramp-up is handled internally. Short-circuit protection latches off the outputs if the speaker terminals see a hard short, which avoids a blown amplifier channel during assembly test or a wiring fault in the field.
