AH266

High Voltage Hall Effect Latch

Features

General Description

- On-chip Hall plate

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.

- Operating voltage: 4V~28V

- Output current: 400mA(Continuous, 25^oC)

- Reverse protection diode only for chip reverse

(Note)

power connecting

- 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).

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^oC to 85 ^oC and voltage

range from 4V to 28V. The devices are available in

low cost die forms or rugged 4 pin SIP packages.
