KUALA LUMPUR, Dec 10 -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has launched ‘TB9045FNG’, a general-purpose system power IC with multiple outputs achieving functional safety for automotive applications.
The new IC is available in four versions, with output voltages ranging from 1.1V to 1.5V. Mass production is scheduled to start this month, according to a statement.
It also integrates various failure detection functions such as high-voltage and low-voltage detection, overheat detection and frequency monitoring of power supply circuit to monitor against the IC’s own failure.
In addition, the new IC also functions as a watchdog timer to monitor failure detection of the external microcontroller. An initial diagnosis circuit to detect latent faults in the failure detection circuits is also incorporated to secure higher functional safety.
Toshiba has carried out a range of functional safety analyses to simulate system failures and will provide customers with documentation, such as functional safety FMEDA, to support overall safety analysis and design.
