For Variable Speed Control
Three-Phase Brushless Motor Predriver
Overview
The LV8104V is a pre-driver IC designed for variable speed control of 3-phase brushless motors. It can be used to
implement both upper and low output N-channel power FET drive circuit using a built-in charge pump circuit.
High-efficiency drive is possible through the use of direct PWM drive and synchronous rectifyication.
Functions
• VCC max = VG max = 42V
• Three-phase bipolar direct PWM drive
• Built-in charge pump for the upper side gate drive voltage generation
• Speed discriminator and PLL speed control system
• High efficiency drive by synchronous rectification
• 5V regulator output
• Start/Stop switching circuit(power save state in a stop mode)
• Forward/reverse switching circuit
• Braking circuit (short braking)
• Built-in FG amplifier and integrating amplifier
• Built-in VCO circuit
• Speed lock detection output
• Current limiter
• Constaint protection circuit
• Clock disconnection protection circuit
• Thermal shutdown protection circuit
• Low-voltage protection circuit
