XD33035 – Brushless DC Motor Controller – Xinluda

The Xinluda XD33035 is a high-performance, second-generation monolithic brushless DC (BLDC) motor controller in a DIP-24 package, providing complete open-loop three- or four-phase motor control with 10-30V operation, rotor position decoding, and integrated protection.

The XD33035 from Xinluda is a high-performance, second-generation monolithic brushless DC (BLDC) motor controller that integrates all of the active functions required to implement a full-featured open-loop, three- or four-phase motor control system. Supplied in a through-hole DIP-24 package, the XD33035 is a functional equivalent of the industry-standard 33035 controller family (the surface-mount SOP-24 sibling is the XL33035).

The device combines a rotor position decoder for proper commutation sequencing, a temperature-compensated 6.25 V reference capable of supplying sensor power, a frequency-programmable sawtooth oscillator, three open-collector top drivers, and three high-current totem-pole bottom drivers ideally suited for driving external power MOSFETs in a 3-phase bridge.

Key Features

• 10 V to 30 V supply operation
• On-chip 6.25 V reference capable of supplying sensor power
• Rotor position decoder for proper commutation sequencing
• Selectable 60°/300° or 120°/240° sensor phasings
• Three open-collector top drivers and three high-current totem-pole bottom drivers for external 3-phase MOSFET bridge control
• Fully accessible error amplifier for closed-loop servo applications
• Frequency-programmable sawtooth oscillator
• Cycle-by-cycle current limiting with selectable time-delayed latched shutdown
• Undervoltage lockout and internal thermal shutdown
• Unique fault output that interfaces directly to microprocessor-controlled systems
• Supports open-loop speed, forward/reverse direction, run enable, and dynamic braking; can also efficiently control brush DC motors with an external MOSFET H-bridge
• Operating ambient temperature range: -40°C to +85°C

Applications

• Three- and four-phase brushless DC motor drives
• Industrial and HVAC fan and blower control
• Pump and compressor motor control
• Office automation and appliance motors
• Closed-loop servo and speed-control systems
• Brush DC motor control with external H-bridge
