Toshiba Corporation has launched the TB9051FTG, a small-sized motor driver IC for dc brushed motors intended primarily for automotive electronic throttle control. The TB9051FTG offers highly efficient operation and a small P-QFN28 package (6mm x 6mm), realized by its ultra-low on-resistance, the result of applying DMOS transistors as driver circuits. Sample shipments will start in September 2015, with mass production scheduled to start in October 2016.

Recommended: 1206- and 1210-size MLCCs in the over-100µF range

While primarily targeting vehicle engine applications, such as electronic throttle and valve control, the new device can be also suitable for the control of on-board systems operating at up to 5A, such as control of wing mirrors and trunk locks. Toshiba has also carried out a range of functional safety analyses to simulate various system failures and will provide customers with documentation to support safety analysis and design. The TB9051FTG will be showcased this week during Techno Frontier to be held in Japan from May 20 to 22.

Key features include: Ultra-low on-resistance (H + L-side: 0.34Ωmax) is realized by applying DMOS transistors as driver circuits in an IC fabricated with cutting-edge process technology. The small flat package (P-QFN28-0606-0.65) is realized by the ultra-low on-resistance. Suited for small mounting boards. Built-in detection circuits include over current, over heat, low voltage and high voltage. Control functions include Forward, Reverse and Brake. The TB9051FTB features pwm control, H-side current monitor, a diagnosis output, and a Power On Reset (POR) circuit.
