TB2901H TOSHIBA Bi-CMOS Digital Integrated Circuit Silicon Monolithic TB2901H Maximum Power 47 W BTL × 4-ch Audio Power IC The TB2901H is 4-ch BTL audio amplifier for car audio applications.
This IC can generate higher power: POUT MAX = 47 W as it includes the pure complementary P-ch and N-ch DMOS output stage.
It is designed to yield low distortion ratio for 4-ch BTL audio power amplifier, built-in standby function, muting function, and various kinds of protectors.
Additionally, high-side swi
