Hall element bias circuit
The hall element bias current is turned off when the driver IC is in standby state.
Make sure that the negative hall bias line is connected to the HB pin.
The remaining voltage is as follows;
VHB = 1.3[V] (typ.) at IHB = 20mA.
IHB must be set less than 20mA.
FG amp circuit
This circuit uses a hall element signal which is output to FGO after a Schmitt stage.
The FG amp has a hysteresis of 20[mVP-P] (typ.) and its output voltages are
High level
: VCC 0.5 to VCC[V]
Low level
: GND to 0.5[V] at IOFG = 10 A
The FG amp is active when it is in standby state. When the hall element signal is input, the FG signal is output.
