Six-step driving method with current control
In this configuration only one sense resistor are needed, the three OUT pins are connected
The non-inverting input comparator CP+ monitors the voltage drop across the external
sense resistor connected between the source of the three lower power MOS transistors and
ground.
As the current in the motor increases the voltage across the RSENSE increases
proportionally. When the voltage drop across the sense resistor becomes greater than the
reference voltage applied at inverting input CP- the comparator open-drain output is
switched on pulling down the CPOUT pin.
This signal could be managed by controller to generate the proper input sequence for six-
step driving method with current control and select what current decay method to
implement.
When the sense voltage decrease below the CP- voltage, the open-drain is switched off and
the voltage at CPOUT pin start to increase charging the capacitor C3.
The reference voltage at pin CP- will be set according to sense resistor value and the
desired regulated current (VCP- { RSENSE x ITARGET). A very simple way to obtain variable
voltage is to low-pass filter a PWM output of a controller.
