TB9044FNG is the universal IC for providing electric power supply systems of functionality of safety of cars.
On January 11, 2016 the Toshiba corporation announced release of the IC TB9044FNG for providing the systems of functional safety of cars.
The IC provides the high level of functional security necessary for compliance of construction of the car to requirements of standards of ASIL-D.
The IC TB9044FNG is issued in the HTSSOP48-P-300-0.50 body the sizes of 6.1 mm x 12.5 mm x 1.0 mm.
The automobile systems crucial in terms of security, such as electroamplifier of steering (EUR) and brake system, should conform to requirements of the ASIL-D standard, the set standards of functional security of ISO 26262.
The integrated circuit has different functions of fault detection - detection of high and low tension, overheating of the scheme of the power source for monitoring of internal failures of the IC, the sentry timer for monitoring of failures of the external microcontroller.
Also the scheme of initial diagnostics for detection of the hidden malfunctions in detection circuits of faults is used that provides higher level of functional security.
The highly effective combined IC direct current converter provides voltage output of 6 V. For prevention of the problems connected with voltage drop at engine start, the lower bound of range of operating voltages makes only 2.7 V (min.) during the work from the accumulator.
Toshiba carried out a number of analyses of functional security with simulation of system failures and provides to customers documentation (for example, FMEDA for functional security) for the general analysis of security and design.
The IC has four output circuits of power supply with consecutive connection receiving input voltage of 6 V from the direct current converter. It contains the output circuit with constant voltage of 5 V (a permissible current 400 mA) for a microcomputer and three schemes with constant voltage output of 5 V (a permissible current 100 mA) for sensors and other interfaces. All these schemes provide independent tension at the exit.
The beginning of serial production is planned for October, 2017.
