Preliminary TCB702FNG CDMOS Linear Integrated Circuit Silicon Monolithic TCB702FNG
Maximum Power 45 W BTL × 4-ch Audio Power IC with Built-in Self-Diagnostics
1. Outline
The TCB702FNG is a power IC with built-in linear high efficiency 4-channel BTL
amplifier developed for car audio applications.
The amplifier system uses our original high efficiency, class TB (Tied BTL), which
enables saving heat generation to 1/5 (at POUT =0.8W) as compared with
conventional class AB amplifier, and realizes reducing internal temperature rise
of car audio applications. The power loss with output power equivalent to a class
D system (digital amplifier) in about 4 W or less is acquired. Additionally, this
product can realize high efficiency system without peripheral parts (which are
used for LPF and EMI protection) of class D system.
Built-in self-diagnostics allows the data reception and control through I2C bus.
The maximum output power POUT is 45 W using a pure complementary Higher
P-ch and Lower N-ch DMOS output stage. It also includes a standby function, a
mute function, and each protection circuit necessary for car audio. P-HSSOP36-1116-0.65-001
