Datasheet
NCV8613B
Ultra-Low Iq Automotive
System Power Supply IC
Power Saving Triple-Output
Linear Regulator
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.
radio systems and instrument cluster power supply requirements. The
NCV8613B 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 NCV8613B is
intended to supply power to various “always on” loads such as the
CAN transceivers and microcontrollers (core, memory and IO). The
NCV8613B has three output voltages, a reset / delay circuit, and a host
of control features suitable for the automotive radio and instrument
cluster systems.
