NCV8614B: Linear Voltage Regulator, Triple-Output, Power Saving, Ultra Low Iq, Automotive System Power Supply
Description: The NCV8614B is a multiple output linear regulator...
The NCV8614B is a multiple output linear regulator IC's with an Automatic Switchover (ASO) input voltage selector. The ASO circuit selects between three different input voltage sources to reduce power dissipation and to maintain the output voltage level across varying battery line voltages associated with an automotive environment.
The NCV8614B is specifically designed to address automotive radio systems and instrument cluster power supply requirements. The NCV8614B can be used in combination with the 4-Output Controller/Regulator IC, NCV885x, to form a complete automotive radio or instrument cluster power solution. The NCV8614B is intended to supply power to various always on loads such as the CAN transceivers and microcontrollers (core, memory and IO). The NCV8614B has three output voltages, a reset/delay circuit, and a host of control features suitable for the automotive radio and instrument cluster systems.
Operating Range 7.0 V to 18.0 V - Maintains output voltage regulation during battery voltage variation.
Output Voltage Tolerance, All Rails, ±2% - Perfect for supplying new microprocesors as well as input voltage sensitive devices.
< 50 µA Quiescent Current - Meet 100 µA max module car manufacturer quiescent current requirement. Ideal for supplying always on loads.
Independent Input for LDO3 Linear Regulator - Possibility to supply LDO3 from an independent source.
High Voltage Ignition Buffer - Possibility to mute radio output during ignition.
Automatic Switchover Input Voltage Selector - Selects between Input Voltage Sources to reduce power dissipation.
Independent Input Voltage Monitor with a High Input Voltage and Low Input Voltage Indicators - Cost and space saving as no external device is required.
Thermal Warning Indicator with Thermal Shutdown - Provide information about overheating of the device.
Single Reset with Externally Adjustable Delay for the 3.3 V rail - Power on indicator to the microcontroller.
Push-Pull Outputs for Logic Level Control Signals - No external pull-up resistors are required.
AEC-Q100 Qualified - Meet automotive qualification requirements.
