Toshiba Electronic Devices & Storage Corporation contributes to increasing mileage for the purpose of handling environmental issues. Taking advantage of the shift to electric vehicles (EVs) and plug-in hybrid vehicles (PHEVs), Toshiba's technology enables efficient use of electric power. 

Air-Conditioning (HVAC) - Compressors offer improved fuel efficiency, with various motors being replaced by brushless motors. MOSFETs are also accompanying this trend with lower power losses. This is required for motor drive and reverse-battery protection applications. Toshiba offers MOSFETs that use a copper (Cu) connector with lower resistance than aluminum in order to reduce conduction loss.

Air-Conditioning (HVAC) - Dampers are motor drivers for HVAC applications incorporating multiple dampers. The product lineup includes ICs that integrate a low-on-resistance driver capable of controlling multiple channels. It also includes those that integrate a driver to provides fine temperature regulation and other features through LIN communications with system electronics.

Automotive Devices in Small Packages offer various types of semiconductors for automotive applications, including mechanical relay drive, LED control, battery cell balancing, and protection of the CAN and LIN buses. Toshiba's portfolio includes an array of devices certified for AEC-Q100 and AEC-Q101, reliability specifications for automotive electronics.

Automotive Drive System (Inverter) generally, HEVs, PHEVs and EVs use three-phase brushless motors for electric propulsion. Because the vehicle drive battery supplies a DC current, it needs to be converted to a three-phase AC current using an inverter. A three-phase inverter, which is composed of power devices, converts DC to AC during acceleration (powering) and converts AC to DC during braking (regeneration), to recharge the battery.

Battery Monitoring System (BMS) are MOSFETs used to optimally balance the voltage among high-voltage battery cells. Photocouplers with low power consumption help reduce the power loss incurred by continuous battery monitoring.

Body Control Modules (BCM) consist of two types. Those that use mechanical relays and those that use MOSFETs as semiconductor relays instead of mechanical relays. Toshiba developed the SSM3K337R to meet the needs of mechanical-relay drive applications. The SSM3K337R is a MOSFET housed in a small package with 85% of the mounting area of the predecessor. The device has active clamping circuitry for inductive loads. Toshiba also offers power MOSFETs like those in the DPAK+ package suitable for semiconductor relay applications.

Cooling Fans for automobiles come in various sizes for the engine, battery pack and LED headlights. With the increasing uptake of electric vehicles (EVs), the market demand for quieter fan motors is growing. Toshiba's sine-wave motor controller ICs help realize quiet motor operation.

Direct Injection are switches for high-pressure injector control applications and MOSFETs suitable for DC/DC converter applications. More and more gasoline cars are equipped with a direct-injection engine to improve fuel efficiency. 

Electric Parking Brake (EPB), Precrash Seat Belt Tensioners are used in automotive applications that rely on electronic control, including electric parking brakes (EPB) and precrash seat belt tensioners. The H-bridge circuit configuration is most commonly used to drive motors for these applications. The DPAK+ MOSFET Series for motor drive applications is fabricated using the latest silicon process and delivers low on-resistance, and low wiring resistance by the use of a Cu connector. These characteristics combine to help reduce the system power consumption. Toshiba also offers pre-drivers that integrate various detection circuits (for undervoltage detection, FET short-circuit detection, thermal shutdown), a charge pump and a high-speed pre-driver circuit.

Electronic Power Steering (EPS) Systems are finding widespread use in automobiles to improve mileage. Available is the TB9081FG Three-Phase Brushless Motor Pre-driver IC for EPS Applications. This device is designed for high-current applications like EPS.

Gasoline Engine Systems are suitable for the control of throttle and exhaust gas recirculation (EGR) valves to help optimize engine efficiency. This accompanies the tightening of environmental regulations, for automotive engines that are required to meet the standards for
higher efficiency and lower emissions.

Pump Control (for Water, Oil and Fuel) includes the TB9061AFNG that controls a pump control unit without using a microcontroller and Hall sensors. This eliminates the need for the development of software for electronic control units (ECUs). It reduces the workload for the development. Moreover, the reduction in the number of components due to the elimination of Hall elements etc. helps reduce the size of ECU boards. Toshiba's semiconductor devices designed for pump control units tolerate a high-temperature environment of up to 125°C in an engine compartment.

Start-Stop Systems are power devices and driver ICs that can be combined to build efficient circuits for the charging/discharging control of lead-acid batteries, lithium-ion batteries and generators in start-stop systems.

System Power Supply ICs are ideal for power supply applications for electronic power steering systems that require an extremely high level of safety.

Transmission Control are semiconductor devices with a current drive capability and various protection features. The devices are suitable for on-off and linear solenoids in transmissions. The hydraulic control in the transmission is driven by a valve using an electromagnetic solenoid.

Realization of automated-driving cars requires cars to be connected to social infrastructures like traffic information and signal
information. It be capable of judging environmental changes through communication with other cars in front and behind.
Connected cars must be provided with advanced infotainment systems that allow communication between cars and drivers. Toshiba
Electronic Devices & Storage contributes to "connection" and "communication" through its technology.

Remote Keyless Entry (RKE) systems are used to lock and unlock vehicle doors. Smart keys can also start engines remotely. Generally, on the push of a button on a key fob, an RF signal is transmitted to a receiver in the vehicle body. This decodes the signal and sends the information to an in-vehicle system.

Tire Pressure Monitoring System (TPMS) is an electronic system designed to monitor the air pressure in vehicle tires. TPMS consists of sensor modules (transmitters) in the wheels and receivers in the vehicle body. TPMS is now legally required in North America, Europe, and Korea. The Chinese and Japanese governments are also deliberating on legislation that mandates the installation of TPMS on all vehicles.

1-Channel Audio Power Amplifier ICs are fabricated using a 0.13µm process with low on-resistance. The ICs are provided with various built-in circuits for in-vehicle protection to provide high reliability. Toshiba is expanding its portfolio of unique high-efficiency Class-TB linear amplifiers to fulfill market needs for low power consumption and environmental friendliness.
