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, a

Schmitt trigger to provide switching hysteresis for noise rejection,

and complementary Darlington open-collector drivers for sinking

large current loads. An internal band-gap 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 operation point (Bop),

DO will turn on (low) and DOB will turn off (high). The output state

is latched prior to reaching release point (Brp). If B< Brp, DO will

turn off and DOB will turn on. AH266 is rated for operation over

temperature range from -20

4V to 28V. The devices are available in low cost die forms or

rugged 4 pin SIP packages.
