Product Overview
Product Description
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, 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.
