TDF8599
I2C-bus controlled dual channel 43 W/2 Ω single channel
85 W/1 Ω class-D power amplifier with load diagnostics
Rev. 01 — 13 November 2008
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 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 when an external resistor is
connected to pin ADS.
When pin ADS is short circuited to ground, 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.
