Description

the that of the RF pin.

VS1
VS2
8 V to 15 V Output block power supply
A diode is internally connected between VS1 and
this pin to prevent reverse current flow in half-wave
operating mode.
Ground sensing.
The influence of the common ground impedance on
Rf can be excluded by connecting this pin to the
ground near the Rf resistor in the motor ground lines
that include RF. (This pin must not be left open.)
3
GSENSE
Output current detection.
Current feedback is applied to the control block by
inserting the resistor Rf between these pins and
ground. Also, both the lower side saturation
prevention circuit and the torque ripple correction
circuit operate according to the voltage on this pin. In
particular, since this voltage sets the oversaturation
prevention level, the lower side oversaturation
prevention operation can be degraded if the value of
this resistor is set too low.
