... INTEGRATED THERMAL PROTECTION POWER SUPPLY OVER VOLTAGE PROTECTION FLEXIWATT POWER PACKAGE WITH 27 PIN BASH® LICENCE REQUIRED DESCRIPTION The STA5150 is a fully integrated power module de- signed to implement a BASH® amplifier when used in conjunction with STABP01 digital processor. GND -VS OUT_ PRE TRK ...

... STA5150 DESCRIPTION (continued) Notice that normally only one Digital Converter is needed to supply a stereo or multi-channel amplifier system, therefore most of the functions implemented in the circuit have summing outputs The signal circuits are biased by fixed negative and positive voltages referred to Ground. Instead the final stag the output amplifiers are supplied by two external voltages that are following the audio signal ...

... STA5150 Gain without compression (G) Max Attenuation ratio The following graph gives the representation of the Compressor activation status related to the Vthreshold and the input voltage. The delimitation line between the two fields, compression or not, is expressed by the formula : Where G is the preamplifier gain without compression. ...

... The response time of the system must be less than 200 Sec to have an effective protection. As further protection, when Ipd reaches an higher threshold (when the dissipated value is higher then 120W) the chip is shut down, forcing low the Stby/Mute pin, and the turn on sequence is restarted STA5150 |Vinpk 9/14 ...

Under the curve of the 64W power, the chip is in normal operation, over 120W the chip is forced in Standby. This last status would be reached if the digital converter does not respond quikly enough reducing the stress to less than 120W ...
