Toshiba Launches Newest Low-Standby Current Regulator For Automotive Applications

Device Supports Automotive Grade 5-Volt Microcontrollers to Reduce Standby Power Consumption in Car Electronic Systems

Toshiba America Electronic Components, Inc. (TAEC)*, acommitted leader that collaborates with technology companies to createbreakthrough designs, today launches its TB9021FNG device–a low-standbycurrent, low-power, high-temperature and mission-critical 5V/200mA linearregulator supporting automotive grade 5-volt microcontrollers. The deploymentof the TB9021FNG, with automotive grade 5-volt microcontrollers, providesautomobile makers with reliability, power, and cost benefits in the design ofentertainment, information, safety, and driver assistance systems for the nextgeneration of automobiles.

“Reduction of system standby power consumptionbecomes increasingly important as the number of electronic components in newcars increases dramatically,” says Deepak Mithani, senior director of theMixed Signal Business Unit, System LSI Group at TAEC. “Nowadays, thehundreds of electronic components required for new car features present standbypower consumption challenges. Having a low-standby power regulator in thesystem will not only manage the power usage during normal operation, but willalso help preserve battery life especially when a vehicle has not been operatedfor an extended period of time.”

The TB9021FNG is fabricated with Toshiba’s low-powerconsumption, fine-pitch BiCD process. This process realizes a reduction ofstandby current to 25 percent from the company’s previous products(1), down totypical 30uA. The new device contributes to a reduction of external componentsby integrating an output power MOSFET required by high-performance automotiveelectronic subsystems. Additionally, the TB9021FNG offers key protections ofreverse battery connection, over-temperature detection, and an over-currentlimiter to prevent output shorted to ground or a “current hogging”situation. The TB9021FNG also features a watchdog function to reset the MCUpower under abnormal clock signals condition. The part is rated 50V input withan operating temperature of -40( )degrees( )Celsius to +125( )degrees()Celsius. The TB9021FNG is housed in a design friendly and efficient 5.0mm x4.4mm (0.65mm pitch) HTSSOP16 package.


Sample shipments are expected to begin on February 2014,with mass production scheduled to start July 2014.
