NCV8855
Quad-Output Automotive
System Power Supply IC
with Integrated High-Side
2A Switch
The NCV8855 is a multiple output controller / regulator IC with an
integrated highâside load switch. The NCV8855 addresses automotive
radio system and instrument cluster power supply requirements. In
addition to the highâside load switch, the NCV8855 includes a
switchâmode power supply (SMPS) buck controller, a 2.5 A SMPS
buck regulator and two low dropout (LDO) linear regulator
controllers. The NCV8855 in combination with the ultraâlow
quiescent current NCV861x IC forms an eightâoutput automotive
radio or instrument cluster power solution. The NCV8855 has an
internally set switching frequency of 170 kHz, with a SYNC pin for
external frequency synchronization.
The NCV8855 is intended to supply power to various loads, such as
a tuner, CD logic, audio processor and CD / tape control within a car
radio. The highâside switch can be used for a CD / tape mechanism or
switching an electricallyâpowered antenna or display unit. In an
instrument cluster application, the NCV8855 can be used to power
graphics display, flash memory and CAN transceivers. In addition, the
highâside switch can be used to limit power to a TFT display during a
battery overâvoltage condition.
