SOP16 packaging

JY01 composed of medium-power Hall and sensorless brushless controller board, 6 pcs TO-220 packed of high-power MOSFET mounted on back of the PCB, the VCC control board voltage in the range Maximum operating current up to 20A (plus appropriate heatsin circuits have been successfully used in such as DC brushless motor ,brushless DC motor pump, scooter motor, handheld devices, etc

N+N framework applications can achieve the needs of high voltage and current, so it is widely used in many DC brushless motor control
higher working voltage or higher working current. This circuit are mature circuits. Circuit due to high stability, easy production and the costs is low and can be facilitated for modular production.

JY01 is integrated 2 in 1 control IC for Hall or sensorless brushless DC motor, which makes it very easy to application in use, please pay attention before circuit design and application.

1: JY01 for Hall sensor motor driver, connect Pin 1 to Vss or connect 5V while power on, JY01 will drive as Hall way.

2: JY01 for Sensorless motor driver, offer 0.1V -4V to Pin 1, JY01 will drive as Sensorless way.

Pin 1 is multi-function pin, there are three operational states:

1: JY01 in application settings when power on.
2: This pin is a Enable control pin under Hall way,High-level voltage is normal drive,Low-level voltage is
forbidden-drive (no output)
3: This pin is Start torque adjustment pin under Sensorless way,voltage range:0.1V-2V.
Please confirm the application state of JY01 before the design.

a) Start torque setting:The Start torque setting is important for sensoless motor starting,the
Start torque is related with the motor performance. the motor will not start or hard to start if
the start torque is small,the motor will shake or reversing if the Start torque is too high.
Initial application debugging according to the motor load,follow the steps as follow:
i.Connect a 20K potentiometer to 0 V and 5 V ,the middle pin connect to JY01 IC I pin.
ii.Adjust the potentiometer to 0 V (Start torque 0) when power on.
iii.Input speed regulation signal to VR pin from 0V to 5V,and check the motor start or not
iv.If the motor can not start or start abnormal,can add the potentiometer value to 0.1 V then
repeat Step iii, if the motor still not start,then add to 0.2V/0.3V/0.4V of the potentiometer and
repeat Step iii till the motor start.
v.If the motor reversing when start,it means the Start torque is high,it should reduce the Start
torque for normal start, Otherwise long time reversing will damage the motor and MOSFET.
b) Overload protection and current sampling resistance setting:JY01 has perfect overload
protection function,it has overload protection and abnormal current protection function
when the current sampling resistor value R is correct set. When Is pin voltage meet to
0.1V,overload monitoring will start,and turn to Constant current state,the drive current will not
change, no matter the VR voltage getting higher or lower and the load getting bigger or
less.In this state,JY01 will keep offering constant drive power to motor. if the Is pin voltage
meet to 0.2V or more ,the protection will activated in 4.5 μs.
R value selection method
R value formula I = 0.1/R
I:value of constant current (unit:Amp)
0.1: JY01 Is pin voltage
R:current limit resistance(unit:Ohm)
For example:working current:3A,set the safety constant current to 5A , when the current
meet to 5A or more,the programme will keep the current at 5A.so according to formula
I=0.1/R, R=0.1/5=0.02 Ohm,so Overload protection and current sampling power resistor
should be 20 mOhm
c) Blocking protection:the blocking protection will activated and stop output if the motor not
start normal in 3 second, reduce the VR voltage to 0 to quit the protection, rise the VR voltage
to restart the motor.
