Quad-Output Automotive System Power Supply IC with Integrated High-Side 2A Switch

ON Semiconductor 

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 high−side load switch. The NCV8855 addresses automotive

radio system and instrument cluster power supply requirements. In

addition to the high−side load switch, the NCV8855 includes a

switch−mode 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 ultra−low

quiescent current NCV861x IC forms an eight−output 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 high−side switch can be used for a CD / tape mechanism or

switching an electrically−powered 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

high−side switch can be used to limit power to a TFT display during a

battery over−voltage condition.
