Application Circuit Example 1
*1.Power supply and ground lines
The IC ground is the control current power supply system ground, and the external n-channel transistor ground is the motor power
supply system ground.
These two systems should be formed from separate lines and the control system external components should be connected to the
IC ground.
*2. Regeneration power supply stabilization capacitor
Use a 4.7F/25V capacitor at least for CM, which is the power supply stabilization capacitor for both PWM drive and kickback
absorption.
The capacitor CM must be connected to prevent destruction of the IC when power is applied or removed.
*3.Speed Control
(1) Control voltage
The PWM duty is determined by comparing the VTH pin voltage with the PWM oscillator waveform.
When the VTH voltage falls, the on duty increases and when the VTH voltage falls below the PWM output low level, the duty will
go to 100%.
(2) Thermistor
For thermistor applications, normally the 6VREG level will be resistor divided and the divided level input to the VTH pin.
The PWM duty is changed by changes in the VTH pin voltage due to changes in temperature.
*4. Current limiter setting
The current limiter circuit operates if the voltage across the resistor between VCC and the VM pin exceeds 0.5V.
Since the current limiter circuit applies limitation at a current determined by IO = VRf/Rf (where VRf = 0.5V (typical), Rf:
resistance of the current detection resistor), the current limiter will operate at IO = 1A when Rf = 0.5Ω.
The resistor RF must be connected in the circuit and it must have a value such that the circuit operates within the recommended
current limiter operating range.
