Protection Built-in Thermal Shutdown Protection Thermally Enhanced SOP-8 Package for
MTD6501C and MTD6501G (Maximum Output
Current – 800 mA); MSOP-10L Package for MTD6501D (Maximum
Output Current – 500 mA) 20 kHz PWM Output Frequency for MTD6501C/D
and 23 kHz for MTD6501G Boost Mode (Optional Back Electromotive Force
(BEMF) Pre-amplification in MTD6501D) No External Tuning Required The MTD6501C/D/G devices are 3-phase, full-wave
drivers for brushless sensorless DC motors. They
feature 180В° sinusoidal drive, high torque output, and
silent drive. Due to their adaptive features and wide
power-supply range capabilities (2V to 14V), they are
intended to cover a wide range of motor characteristics,
while requiring no external tuning from the user. Speed
control can be achieved through either power supply
modulation or pulse-width modulation (using the PWM
digital input pin). The MTD6501C/D/G devices are formerly products of
Advanced Silicon. Due to the compact packaging and minimum bill of …
