Datasheet  
Power Supply IC Series for TFT-LCD Panels  
Automotive Panel Power Management IC  
BD81842MUV-M  
●Applications  
TFT-LCD Panels which are used in car navigation,  
in-vehicle center panel, and instrument cluster.  
●General Description  
The BD81842MUV-M is a power management IC for  
TFT-LCD panels which are used in car navigation,  
in-vehicle center panel, and instrument cluster.  
Incorporates high-power FET with low on resistance for  
large currents that employ high-power packages, thus  
driving large current loads while suppressing the  
generation of heat. A charge pump controller is  
incorporated as well, thus greatly reducing the number  
of application components. Also Gate Shading Function  
is included.  
●Features  
AEC-Q100 Qualified(Note 1)  
Boost DC/DC converter; 18 V / 2.5 A switch current.  
Switching frequency: 2.1 MHz  
Operational Amplifier (short current 200mA)  
Incorporates Positive / Negative Charge-pump  
Controllers.
