Toshiba shipping IC samples for automotive applications
The devices support high output current in combination with an external power transistor
Sample shipments have started, with mass production scheduled to start in December 2014.
The TB9005FNG supports 1A or higher output current in combination with external power transistors, allowing use in automotive applications that require high output current.
The IC also incorporates system reset functions for reset of microcontrollers when their voltage is lowered or clock signals are cut off, which contributes to improved safety for automotive systems.
Applications can be used for automotive applications using 5 V microcontrollers.
