voltage regulator
Rev. 01 — 3 December 2008
Objective data sheet
1. General description
1.1 Amplifiers
www.DataSheet4U.com
The TDF8553 has a complementary quad audio power amplifier that uses BCDMOS
technology. It contains four amplifiers configured in Bridge Tied Load (BTL) to drive
speakers for front and rear left and right channels. The I2C-bus allows diagnostic
information of each amplifier and its speaker to be read separately. Both front and both
rear channel amplifiers can be configured independently in line driver mode with a gain of
20 dB (differential output) or amplifier mode with a gain of 26 dB (BTL output).
1.2 Voltage regulators
The TDF8553 has a multiple output voltage regulator with two power switches.
The voltage regulator contains the following:
Four switchable regulators and two standby regulators
Two power switches with loss-of-ground protection and surge protection
Second supply pin to reduce dissipation by means of an external DC-to-DC converter
2. Features
I Amplifiers
N I2C-bus control
N Can drive a 2 load with a battery voltage of up to 16 V and a 4 load with a
battery voltage of up to 18 V
N DC load detection, open, short and present
N AC load (tweeter) detection
N Programmable clip detect; 1 % or 4 %
N Programmable thermal protection pre-warning
N Independent short-circuit protection per channel
N Selectable line driver (20 dB) and amplifier mode (26 dB)
N Loss-of-ground and open VP safe
N All outputs protected from short-circuit to ground, to VP or across the load
N All pins protected from short-circuit to ground
N Soft thermal-clipping to prevent audio holes
N Low battery detection
