Toshiba Electronics Europe has launched a range of general-purpose system power ICs with multiple-outputs. The new devices aid functional safety according to ISO26262 for safety-critical automotive applications comprising those that demand extremely high safety such as EPS and braking systems where ASIL-D is needed.
The series consists of four devices with multiple output voltages generated by a buck converter – 1.1V (TB9045FNG-110), 1.2V (TB9045FNG-120), 1.25V (TB9045FNG-125), and 1.5V (TB9045FNG-150). The four output voltages from these devices can be employed to power the core of an MCU, as well as using for sensors and other interfaces.
A buck-boost converter generates 6V from the automotive battery and can operate with input voltages as low as 2.7V to ensure constant voltage, even through cranking operations when the battery voltage drops significantly. The devices are ideal for input voltages as high as 18V and can operate over the temperature range -40C to +125C. They are housed in a very small HTSSOP48-P-300-0.50 package, measuring just 6.1mm x 12.5mm x 1mm making them excellent for modern densely packed automotive applications.
