AH266
High Voltage Hall Effect Latch
Features
- On-chip Hall plate
- Operating voltage: 4V~28V
- Output current: 400mA(Continuous, 25
o
C)
- Reverse protection diode only for chip reverse
power connecting
(Note)
- Output protection Zener breakdown Vz=62V(Typ)
- Package: SIP-4L
(Note)
Protection diode only exists at power pin(1,4) output, not
including pin (2,3).
General Description
AH266 is an integrated Hall sensor with output
drivers designed for electronic commutation of
brush-less DC motor applications. The device
includes an on-chip Hall voltage generator for
magnetic sensing, a comparator that amplifies the
Hall voltage, and a Schmitt trigger to provide
switching hysteresis for noise rejection, and
complementary darlington open-collector drivers for
sinking large current loads. An internal bandgap
regulator is used to provide temperature
compensated supply voltage for internal circuits and
allows a wide operating supply range.
If a magnetic flux density (B) is larger than operate
point (Bop), DO turn on (low) and DOB turn off
(high). The outputs state is latched prior to reach
release point (Brp). if B< Brp, DO turn off and DOB
turn on. AH266 is rated for operation over
temperature range from -20
o
C to 85
o
C and voltage
range from 4V to 28V. The devices are available in
low cost die forms or rugged 4 pin SIP packages.
