PT2434 Overview
The PT2434 is a three-phase, sensor-less, brushless DC motor control chip. System operating voltage depends on the VM (motor voltage), from 12V to 400Vdc. On-chip LDO can provide 5V voltage for logic and analog circuits operation.
PT2434 Key Features
- Sensor-less 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
