TDF8599

I²C-bus controlled dual channel 43 W/2 Ω single channel

85 W/1 Ω class-D power ampliﬁer with load diagnostics

Rev. 02 — 30 July 2009

Product data sheet

1. General description

The TDF8599 is a dual Bridge-Tied Load (BTL) car audio ampliﬁer comprising an

NDMOST-NDMOST output stage based on SOI BCDMOS technology. Low power

dissipation enables the TDF8599 high-efﬁciency, class-D ampliﬁer to be used with a

smaller heat sink than those normally used with standard class-AB ampliﬁers.

The TDF8599 can operate in either non-I²C-bus mode or I²C-bus mode. When in I²C-bus

mode, DC load detection results and fault conditions can be easily read back from the

device. Up to ﬁve I²C-bus addresses can be selected depending on the value of the

external resistor connected to pins ADS and MOD.

When pin ADS is short circuited to pin AGND, the TDF8599 operates in non-I²C-bus

mode. Switching between Operating mode and Mute mode in non-I²C-bus mode is only

possible using pins EN and SEL_MUTE.

2. Features
