General Description

FD115MH/FD115MAis a two coil motor driver with embedded Hall sensor. It integrates the motor driver with the Hall

sensor, which simplifies the PCB(printed circuit board) design and make the fabrication of small-size motors

possible.

Lock-shutdown and auto-restart function keeps the motor from being over-heated and restarts the motor after being

locked.

“Soft-switch” phase-switching technique is used to reduce the vibration and acoustic noise.

Thermal-shutdown protection ensures the motor driver to operate under specified temperature ranges.

All the protection mechanisms mentioned above combine to provide a complete protecting scenario for the motor

system, keep the motor system from possible damages and guarantee correct operations.

Functional Descriptions

Refer to the block diagram (Figure.1), FD115MH/FD115MA is composed of the following building blocks:

ꢀ

Bias generator

The bias generator provides precise, temperature- and process-insensitive bias references for the analog circuit

blocks. These references guarantee proper operation of the IC under all conditions specified in this specification.

ꢀ

Oscillator

The built-in oscillator provides the clock signal for the digital control logics

Power-on Reset

ꢀ

Used to detect the power-up ramp and reset the digital circuits to achieve correct operation as soon as the power is

ready.

ꢀ

Chopper Amplifier

To achieve a higher magnetic sensitivity the chopper amplifier structure is adopted in this design. Use of this

structure dynamically removes both the offset and flicker noise at the same time.

ꢀ

Digital control logics

ꢁ

Hall sensor part – generates controlling signals for the Hall sensor.

Coil driver part – generates controlling signals for the Coil driver.
