TDF8546JV Integrated Circuit Chip Automotive Audio Power Amplifiers DBS-27 Package

Product Description Of TDF8546JV
TDF8546JV is one of a new generation of complementary quad Bridge-Tied Load (BTL) audio power amplifiers intended for automotive applications. It has a best efficiency mode with full I2C-bus controlled diagnostics, including start-up diagnostics. The TDF8546JV can operate at a battery voltage as low as 6 V making this amplifier suitable for stop/start-car operation.

Specifications Of TDF8546JV

Features And Benefits Of TDF8546JV
Stop/start-car prepared: keeps operating without audible disturbance during engine start at a battery voltage as lowas 6 V
New best efficiency mode with patented low switching distortion
Extreme best efficiency mode (uses information from 4 channels) with 17 % less dissipation for uncorrelated signals compared to 2-channel best efficiency mode.
Operates in either legacy (non-l2C-bus) or I2C-bus modes (3.3 V and 5 V compliant)
Four hardware-programmable I2C-bus addresses
Candrive2Qand4Qloads
Speaker fault detection
Start-up diagnostics with load detection: open, short, present; filtered for door slam and chatter relays
AC load (tweeter) detection with low and high current mode
Gain select after start-up without audible disturbance
Independent selectable soft mute of front and rear channels
Programmable gain (26 dB and 16 dB), independently programmable for the front and rear channels
Line driver mode supports engine start at a battery voltage as low as 6 V (16 dB and mid-tap voltage 0.25 x Vp)
Programmable clip detect: 2 %, 5 % or 10 %
Programmable thermal pre-warning
Pin STB can be programmed/multiplexed with second-clip detect
Clip information of each channel can be directed separately to pin DIAG or pin STB
Independent enabling of thermal-, clip- or load fault information (short across the load or to Vp or to ground) on pin DIAG
Loss-of-ground and open Vp safe (minimum series resistance required)
All amplifier outputs short-circuit proof to ground, supply voltage and across the load (channel independent)
All pins short- circuit proof to ground
Temperature controlled gain reduction to prevent audio holes at high junction temperatures
Programmable low battery voltage detection to enable 7.5 V or 6 V minimum battery voltage operation
Overvoltage protection (load-dump safe up to Vp = 50 V) with overvoltage pre-warning at16V
Offset detection
