During thermal protection circuit operation
*1:
An FG signal at a frequency corresponding to the phase switching operation is output.
This IC is pin compatible with the LB11963T, which provides a built-in function for dividing the FG output frequency by 2 to handle 8-pole motors.
*2:
In restart mode (output on) when a rotor constrained state was detected, the FG output operates in the same way as during normal operation, and differs
depending on the rotor position.
Pin Assignment
Application Circuit Example
*1: The diode Di prevents destruction of the IC if the power supply is connected with reverse polarity. Since this IC
includes a regeneration circuit, this IC recovers the coil current in the low side pnp output transistors and suppresses
kickback, even when the diode Di is used.
This diode may be omitted if there is no chance of reverse connection problems occurring, for example, if a power
supply connector is used.
*2: This capacitor is required for rectification if power supply PWM is used for speed control.
*3: This pin must be left open if unused.
*4: Although chattering prevention measures, such as adopting a non-interfering pin assignment and providing
hysteresis in the Hall sensor amplifier, these lines must be made as short as possible to make the circuit more
resistant to noise.
