Automotive Brushed DC Motor Driver ICs
A brushed motor is used the most in the type of motor for automotive application.
Toshiba has various of H-Bridge driver ICs which realize system optimization of each ECU, such as the driver IC integrating low Rds(on) Power MOSFETs and supporting LIN communication as a responder or the driver IC capable of 5A using smaller package with heat sink.
Toshiba provides high reliability motor driver IC solution qualifying AEC-Q100.
Product Highlights
Compact Driver IC for automotive electronic throttle control
TB9051FTG provides high efficiency and ultra-low ON resistance
While primarily targeted at vehicle engine applications, such as electronic throttle and valve control, the TB9051FTG is also suitable for control of on-board systems operating at up to 5A, such as control of wing mirrors and locks for car boots. The TB9051FTG is a single channel H-Bridge that supports two power supplies (VBAT and VCC). The TB9051FTG has an operational voltage range of VBAT=4.5V to 28V and VCC=4.5V to 5.5V. In addition to forward, reverse and brake functions, it is also capable of PWM control, current limit control and usable for high-side current monitoring, diagnosis output and power on reset (POR) circuitry. Fabricated with cutting edge process technology to ensure ultra-low on-resistance of 0.34Ω (high-side + low-side, max) the TB9051FTG applies DMOS transistors as driver circuits. The IC also uses various built-in failure detection features for functional safety. These include over current, over heat, low voltage and high voltage detection circuits. The device offers highly efficient operation in a compact P-QFN28 package (6mm × 6mm), well suited for small mounting boards.
10A H-Bridge Motor Driver IC Supporting Dual-Channel
Innovative design enables microcontroller port reduction via daisy-chain connection function
The TB9054FTG and TB9053FTG are driver ICs for brushed DC motors, utilising advanced DMOS FET technology to achieve a low RDSON value. These H-bridge devices are AEC-Q100 Grade 1 qualified and support temperatures up to 150°C junction temperature. Thanks to greater functional integration alongside streamlining of interfaces (e.g., no external capacitor is necessary for charge-pump operation), these Toshiba driver ICs have the capacity to significantly contribute to the downsizing of automotive electronic control units (ECUs). High-precision motor control can be executed via use of just the SPI interface (or through direct PWM control if preferred). This enables port reductions in the host microcontroller to be realised. In addition, built-in diagnostics allow ongoing performance and functional observation. Current monitoring and current limiting features are also incorporated. TB9053FTG is available in a QFN40 thermally enhanced power package with an extraordinary low Rth of just 0.67K/W. Over-current, over-temperature and open load protection mechanisms are all included. Among the key applications for these driver ICs are ETC, EGR, power mirror folding, small fans, grill shutter, camera or OBC lid operation, plus soft power door opening/closing systems.
