TB6537P/F is a three-phase full-wave sensorless controller for brushless DC motors manufactured by TOSHIBA. It supports PWM control, overcurrent protection, forward/reverse modes, lead angle control function.
The Toshiba TB6537P and TB6537F are integrated circuits functioning as 3-phase full-wave sensorless controllers for brushless DC (BLDC) motors. These devices control motor voltage using PWM signals supplied from external sources and can be utilized with various drive circuits to operate different types of motors.
The chips feature a built-in lap turn-on function, overcurrent protection, and lead angle control capabilities ranging from 0 to 30 degrees. They offer two types of PWM output configurations: upper PWM or upper/lower alternate PWM. The TB6537P is available in an 18-pin DIP package, while the TB6537F comes in a 24-pin SSOP package.
