TDA1566
Datasheet
General description
The TDA1566 is a car audio power amplifier with a complementary output stage realized in BCDMOS. The TDA1566 has two Bridge Tied Load (BTL) output stages and comes in a HSOP24 or DBS27P package.
The TDA1566 can be controlled with or without I2C-bus. With I2C-bus control gain settings per channel and diagnostic trigger levels can be selected. Failure conditions as well as load identification can be read with I2C-bus. The load identification detects whether the outputs of a BTL channel are connected with a DC or AC load and discriminates between a speaker load, a line driver load and an open (unconnected) load.
The TDA1566 can be configured in a single BTL mode and drive a 1 Ohm load. For the single BTL mode it is necessary to connect on the Printed-Circuit Board (PCB) the outputs of both BTL channels in parallel.
Features
- Operates in I2C-bus mode and non-I2C-bus mode
- TH version: four I2C-bus addresses controlled by two pins; J version: two I2C-bus addresses controlled by one pin
- Two 4 Ohm or 2 Ohm capable BTL channels or one 1 Ohm capable BTL channel
- Low offset
- Pop free off/standby/mute/operating mode transitions
- Speaker fault detection
- Selectable gain (26 dB and 16 dB)
- In I2C-bus mode:
- DC load detection: open, short and speaker or line driver present
- AC load (tweeter) detection
- Programmable trigger levels for DC and AC load detection
- Per channel programmable gain (26 dB and 16 dB, selectable per channel)
- Selectable diagnostic levels for clip detection and thermal pre-warning
- Selectable information on the DIAG pin for clip information of each channel separately and independent enabling of thermal-, offset- or load fault
- Independent short-circuit protection per channel
- Loss of ground and open VP safe
- All outputs short-circuit proof to VP, GND and across the load
- All pins short-circuit proof to ground
- Temperature controlled gain reduction at high junction temperatures
- Fault condition diagnosis per channel: short to ground, short to supply, shorted lead and speaker fault (wrongly connected)
- Low battery voltage detection
- TH version: pin compatible with the TDA8566TH1
