New, small driver IC utilizes DMOS transistors as driver circuits, enabling highly efficient operation
SAN JOSE, Calif., — Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced a small-sized motor driver IC for DC brushed motors used in vehicle engine applications such as electronic throttles and valve controls. The new TB9051FTG, housed in a small, flat 6mm x 6mm P-QFN28 package, employs double-diffused MOSFET (DMOS FET) transistors as driver circuits.
As with its recently announced line of DMOS FET transistor arrays, Toshiba selected DMOS FET devices for the TB9051FTG driver circuits. As these devices do not require base current biasing, they have virtually no input current, which lets them process high current density per device area with low on-resistance. This enables low output voltage drop – in turn, allowing the new motor driver IC to operate with a high degree of efficiency.
"These new motor driver ICs, due to their small size and underlying technology, have the flexibility to enable control of a range of automotive electronics - not only engine applications, which are the primary target, but also other on-board systems, such as wing mirrors and trunk locks, operating at up to 5 amps," said Deepak Mithani, senior director, Mixed-Signal Business Unit, System LSI Group at TAEC. "Moreover, because user safety is paramount, Toshiba has carried out a range of functional safety analyses to simulate various system failures, and we supply this documentation to our customers to further support their design-in process."
The new TB9051FTG motor driver IC features a single, H-bridge channel and ultra-low on-resistance of 0.34Ω (H-side + L-side, max). Its two power supplies, VBAT and VCC, operate at 4.5V to 28V and 4.5V to 5.5V, respectively. Control functions include motor-related (forward, reverse, brake), as well as PWM control, current limit control, H-side current monitor, diagnosis output and power-on-reset (POR) circuit. Built-in detection circuits include over current, over heat, and low/high voltage.
Sample shipments will start in September 2015, with mass production scheduled to start in October 2016.
