Power device supports compact, high-efficiency BLDC motor drives


Toshiba Electronics has announced a high-voltage intelligent power device (HV-IPD) that will improve the efficiency and reduce the component count of brushless DC (BLDC) motor drives.

The TPD4206F is a multichip IC rated for 500V and 2.5A and offering integrated sine and trapezoidal wave motor control. This makes it ideal for low-power, low-noise motion control applications including industrial fans and pumps and domestic appliances with power ratings up to 80W.

Toshiba’s multichip IC integrates six MOSFETs, a driver IC and protection functionality into a single, 30-pin SOP30 SMD package. High-efficiency operation comes from a combination of ultra-low typical on resistance (RDS(ON) = 1.7Ω) and improved package thermal resistance.

The TPD4206F measures only 20x14.2x2mm. On-board functionality includes over-current, under-voltage and thermal shutdown protection. A typical recovery time (trr) of just 90ns allows the device to meet a wide range of high-performance motion control requirements.

Designers can combine the new HV-IPD with microcontrollers and other driver ICs depending on the needs of the target application. Toshiba also offers an evaluation board that allows engineers to quickly prototype and test designs based on the IC.
