PT2501 Overview
The PT2501 is a three-phase, hall sensor sinusoidal brushless DC motor control chip. The three-phase control is based on sine wave driving scheme and it is designed to reduce electrical audible noise in motor phase mutation. On-chip +5V LDO provide voltage for logic and analog circuits operation.
PT2501 Key Features
- Hall sensor sinusoidal control for 3-phase BLDC
- Current limit function
- Over temperature protection from external NTC
- Motor lock protection
- Reverse function
- PWM or DC input for speed control
- FG output for rotation speed
- Pre-driver for 12V to 24V high side PMOS and
- Support Hall element and Hall sensor
