■ General Description
ATS477 that integrates Hall sensor with output drivers is designed for
electrical commutation of brush-less DC motor application. The device includes
on-chip Hall voltage generator for magnetic sensing, the error amplifier that
amplifies the Hall voltage, a comparator that is to provide switching
hysteresis for noise rejection, the bi-direction drivers for sinking and
driving large current load, and the frequency generator (FG) that provides a
signal proportional to rotation speed. Internal bandgap regulator is used to
provide temperature compensated bias for internal circuits and allows a wide
operating supply voltage range. Built-in protection circuit and output shunt
Zener diodes were applied for protecting output drivers during operating.
If a magnetic flux density is larger than threshold Bop, DO is turned to sink
and DOB is turned to drive. The output state is held until a magnetic flux
density reversal falls below Brp causing DO to be turned to drive and DOB
turned to sink.
ATS477 is rated for operation over-temperature range from -20 oC to 85 oC and
voltage range from 3.5V to 20V. The devices are available in low cost die
forms or rugged SIP-4L and power SOP-7L packages.
