TENTATIVE Version No.18052009 LV47002P Development Specification Proposal (BTL 4 channel Car Audio Power Amplifier) The LV47002P is

36、 the IC for 4-channel BTL power amplifier that is developed for car audio system. Pch DMOS in the upper side of the output stage and Nch DMOS in the lower side of the output stage are complimentary. High power and high quality sound are realized by that. This IC incorporate various functions (standb

37、y switch, muting function, and various protection circuit) necessary for car audio system. Also, it has a self-diagnosis function. 1. Application : 4-channel BTL power amplifier for car audio system 2. Package type : HZIP25 3. Functions and Features : - High power : - Pomax=48W (typical) (Vcc=15.2V,

39、ffset detection, shorting to VCC, shorting to ground , and load shorting. - Electric mirror noise decrease - Built-in various protection circuit (shorting to ground, shorting to VCC, load shorting, over voltage and thermal shut down ) - No external anti-oscillation part necessary. Note1 : Please do

40、not mistake connection. A wrong connection may produce destruction, deterioration and damage for the IC or equipment. Note2 : The protective circuit function is provided to temporarily avoid abnormal state such as incorrect output connection. But, there is no guarantee that the IC is not destroyed b

41、y the accident. The protective function do not operate of the operation guarantee range. If the outputs are connected incorrectly, IC destruction may occur when used outside of the operation guarantee range. Note3 : External parts, such as the anti-oscillation part, may become necessary depending on

42、 the set condition. Check their necessity for each set. TENTATIVE 2 Note : Information in this document is subject to change without notice. 4.
