Datasheet TB9M040FTG (Toshiba)

Preliminary
TB9M040FTG Bi-CMOS Linear Integrated Circuit Silicon Monolithic
TB9M040FTG
IC for automotive three-phase brushless DC motor
1. Description
The TB9M040FTG is an integrated IC combining an automotive microcontroller unit (MCU) and a motor driver. It incorporates Toshiba’s unique Vector Engine (VE) to simplify motor vector control and reduce CPU load. The product is developed in accordance with ISO 26262 functional safety standards. P-VQFN36-0606-0.50-004 weight: 0.102g (typ.)
2. Applications
For automotive equipment (electric valves, HVAC dampers, flaps, and gril e shutters), three-phase small brushless DC motor control and drive.
3. Features
• System size reduction is achievable through integration of an MCU, a three‑phase brushless DC motor driver, a high‑side driver, a LIN transceiver, and an automotive power supply system. • Built‑in power MOSFETs enable direct drive of three‑phase brushless DC motors. • The high‑side driver output can supply a 5 V power source. • It features Toshiba’s proprietary Vector Engine (VE), which reduces CPU load in FOC motor control applications. • Built‑in BEMF detection enables sensorless motor control.
