Overheat protection
*1 FG equivalent to 1/2 of the frequency corresponding to the phase changeover is output. Accordingly, the same FG
output frequency is available for both eight-pole and four-pole motors. This is compatible with pins of LB11964T
that is the FG output compatible with four poles.
*2 In the restart mode (output ON) during rotor restriction, the FG output causes an operation similar to the one during
rotation and varies depending on the rotor position.
Application Circuit Example
*1 This is Di to prevent breakage due to reverse connection. The built-in regeneration circuit regenerates the coil
current between lower NPN outputs, suppressing kickback.
This may be eliminated if there is no problem because a power connector, etc. is used.
*2 This is necessary for commutation when the rotation speed is to be controlled with power PWM.
*3 Must be left open when not used.
*4 Chattering preventive measure is taken for the FG output by providing the Hall amplifier with hysteresis and by
ensuring the pin arrangement with less interference. It is essential to carry out short wiring to make carrying of noise
difficult.
