Preliminary PT2505 3-Phase Sinusoidal BLDC Motor Controller DESCRIPTION The PT2505 is a three-phase, hall sensor sinusoidal brushless DC motor control chip with different protection mechanism.
The three-phase control is based on sine wave driving scheme and it is designed to reduce electrical audible noise in motor phase commutation.
On-chip +5V LDO provide voltage for logic and analog circuits operation.
Combined with an external high voltage gate driver and six n-channel MOSFETs, PT2505 can operate with high voltage motor.
The PT2505 offers OTP parameters setting to optimize with different motors and applications.
PT2505 with package in SSOP24 and SSOP28.
For SSOP24 package, its pin ass...
