Sine-wave Driving, High Voltage 3-phase Motor Drivers
with Built-in Hall Amplifiers
SX6812xM Series
Data Sheet
Description
The SX6812xM series are high voltage 3-phase motor
drivers driven by a sinusoidal control, which can support
Hall element and Hall IC inputs, thus offering high-
efficient yet low-noise motor control. Supplied in a thin
SOP36 package, where a controller, a gate driver, the
output transistors of three phases, and bootstrap diodes
are highly integrated, the SX6812xM series requires
only a few external components for building a motor
driver. This also allows a motor driver to be highly
reliable in performance and design-friendly with its
compactness. These products can optimally control the
inverter systems of low- to medium-capacity motors that
require universal input standards.
Features
Low Noise, High Efficiency (Sinusoidal Current
Waveform)
Reduced Number of Parts Achieved by Built-in
Bootstrap Diodes with Current-limiting Resistors
Pb-free (RoHS Compliant)
Hall Element and Hall IC Inputs
Application-specific Optimal Settings with External
Signals:
Motor Speed
Phase Adavance Angle
Motor Direction
User-settable Motor Lock Detection (Enabled or
Disabled)
5 V Reference Voltage Output
(Used for Driving Hall Elements etc.)
Fault Signal Output at Protection Activation (FO Pin)
Protections Include:
VREG Pin Undervoltage Lockout (UVLO_VREG)
Undervoltage Lockout for Power Supplies
VBx Pin (UVLO_VB)
VCC1 Pin (UVLO_VCC)
Overcurrent Limit (OCL)
Overcurrent Protection (OCP)
Thermal Shutdown (TSD)
Motor Lock Protection (MLP)
Reverse Rotation Detection
