• Hall element bias circuit
TA8490F
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 = 1.2 [V] (typ.) at IHB = 10 mA
Furthermore, this circuit cannot be used if FG output is necessary in standby state.
When the HB terminal is not used, the negative hall bias line must be connected to GND with a resistor in
between.
• 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~VCC [V]
Low level : GND~0.5 [V] at IOFG = 10 µA
The FG amp is active when it is in standby state. When the hall element signal is input, the FG signal is
output.
