.

Dual power supply voltage design 5/12V and wide voltage handling range.

3V also supported for rotation functions only

.

Constant-voltage Hall bias power supply 1.3V across HB to GND assures stable Hall output over entire temperature

and power supply voltage range. External limiting resistor not required.

.

Built-in Hall amplifier with hysteresis supports core without commutating pole.

.

Built-in lockup protection and automatic recovery circuits External capacitor for rotation detection need only be 0.1µF,

allowing compact, cost-saving design.

.

Built-in output transistor with output withstand voltage 24V max/output current 500mA average, 1A peak.

.

Built-in thermal protection circuit.
