lock detect
The lock detect circuit monitors FGSOUT and flags when it is within
±5% of f(ref). The circuit counts the number
of FG reference clocks which occur between the rising edges of FGSOUT to determine whether motor speed
has reached the locking range. When a lock occurs, the LD terminal transitions low. When the FGSOUT
frequency is not within the
± 5% of f(ref) window, an internal out-of-lock signal is generated for the lock timer block
(see
lock timer section).
Hall signal conditioning
The Hall signal conditioning block receives the low-level differential voltage from naked Hall elements and
implements symmetric threshold detection and hysteresis for noise rejection. The circuit has nominal input
voltage thresholds of
±7 mV at the INx+ pin with respect to the INx– pin. The common-mode input voltage range
is 1.5 V to 3.5 V (see Figure 9).
