Philips Semiconductors
Preliminary specification
Brushless DC motor drive circuit
TDF5242T
FEATURES
Full-wave commutation without position sensors
Built-in start-up circuitry
Six outputs that can drive three external transistor pairs:
– output current 0.2 A (typ.)
– low saturation voltage
– built-in current limiter
Thermal protection
Tacho output without extra sensor
Transconductance amplifier for an external control
transistor
Brake control input
Direction control input.
APPLICATIONS
High-power applications, for instance:
– high-end hard disk drives
– automotive applications.
GENERAL DESCRIPTION
The TDF5242T is a bipolar integrated circuit for driving
3-phase brushless DC motors in full-wave mode.
The device functions sensorless, thus saving 3 hall-effect
sensors, using the back-EMF (Electro Motive Force)
sensing technique to sense the rotor position. It includes
6 pre-drivers able to control external FETs (Field Effect
Transistors) or bipolar transistors. It offers brake and
direction control. It is ideally suited for high-power
applications such as high-end hard disk drives and
automotive applications.
QUICK REFERENCE DATA
Measured over full voltage and temperature range.
Note
1.
An unstabilized supply can be used.
