Advantage of Intelligent Phase Control
Intelligent Phase Control detects the motor current phase and feeds back the information for auto lead angle control. When a motor application has a sensor, the phase of the Hall signal is automatically adjusted to match that of the motor drive current.
High efficiency is achieved regardless of the rpm, load torque and power supply voltage of a motor. Intelligent Phase Control also helps reduce the number of external parts necessary for lead angle adjustment.

*1) Active Gain Control optimizes the drive current to suit the required torque. It´s a Toshiba technology that prevents stalls and realizes power savings.
*2) Advanced Dynamic Mixed Decay automatically optimizes the switching control of fast decay and slow decay modes to secure high speed rotation. It´s a Toshiba original mixed decay technology.
Cordless Power Tool Reference Design
Compact, efficient and flexible control for Brushless DC (BLDC) motor based power tools
The reference design combines Toshiba’s highly efficient low-voltage MOSFET devices with Toshiba’s dedicated motor control MCU and thus provides a very compact but flexible platform for the control and drive of BLDC motors in power tools. The Motor current is generated by a 3-phase inverter with 200W output power stage using the Toshiba TPH1R204PB low-voltage MOSFET. This device features industry-leading RDS(ON) in a 5×6mm SOP Advanced package and provides low spike generation helping to prevent EMI effects.
