BRUSHLESS DC MOTOR CONTROLLER

FSP33035

FEATURES

GENERAL DESCRIPTION

10V to 30 V Operation

The FSP33035 is a high performance second

generation monolithic brushless DC motor controller

containing all of the active functions required to

implement a full featured open loop, three or four

phase motor control system. This device consists of a

rotor position decoder for proper commutation

sequencing, temperature compensated reference

capable of supplying sensor power, frequency

programmable sawtooth oscillator, three open collector

top drivers, and three high current totem pole bottom

drivers ideally suited for driving power MOSFETs.

Also included are protective features consisting of

undervoltage lockout, cycle–by–cycle current limiting

with a selectable time delayed latched shutdown mode,

internal thermal shutdown, and a unique fault output

that can be interfaced into microprocessor controlled

Undervoltage Lockout

6.25V Reference Capable of Supplying Sensor

Power

Fully Accessible Error Amplifier for Closed Loop

Servo Applications

High Current Drivers Can Control External

3–Phase MOSFET Bridge

Cycle–By–Cycle Current Limiting

Pinned–Out Current Sense Reference

Internal Thermal Shutdown

Selectable 60°/300° or 120°/240° Sensor

Phasings

Can Efficiently Control Brush DC Motors with

External MOSFET H–Bridge

Top driver output current not more than 50mA

Bottom driver output current not more than 100mA systems.

SOP24L and PDIP24L Packages Typical motor control functions include open loop

speed, forward or reverse direction, run enable, and

dynamic braking. The FSP33035 is designed to

operate with electrical sensor phasings of 60°/300° or

120°/240°, and can also efficiently control brush DC

motors.
