Description
Direct PWM structure pre-driver

Features
• Three-phase bipolar drive
• Direct PWM drive (controlled either by control voltage or PWM variable duty pulse input)
• Built-in forward/reverse switching circuit
• Start/stop mode switching circuit (stop mode power saving function)
• Built-in input amplifier
• 5 V regulator output (VREG pin)
• Current limiter circuit (Supports 0.25 V (typical) reference voltage sensing based high-precision detection)
• Undervoltage protection circuit (The operating voltage can be set with a zener diode)
• Automatic recovery type constraint protection circuit with protection operating state discrimination output (RD pin)
• Four types of Hall signal pulse outputs
• Supports thermistor based thermal protection of the output transistors
