A1693

Vibration-Tolerant Hall-Effect

Transmission Speed and Direction Sensor IC

FEATURES AND BENEFITS

DESCRIPTION

• Differential Hall-effect sensor IC measures ring

magnets and ferrous targets with inherent stray field

immunity

• Vibration detection algorithms prevent false switching

and provide low-signal lockout

• Large operating air gap with independent switch points

• Three-wire pulse-width output protocol describes speed

and direction

• Wide operating voltage and integrated protection

circuits

The A1693 is a magnetic sensor IC designed for measuring

the speed and direction of rotating transmission systems. This

IC can directly measure ring magnets or be back-biased with

a magnet to measure ferrous targets.

The IC incorporates three Hall-effect elements that sense

differentially,analogsignalconditioningwithdynamicgainand

offset adjustment, analog-to-digital converters (ADCs), and a

digital processor that applies intelligent algorithms to prevent

the output from switching when the sensed target vibrates.

• AEC-Q100 Grade 0 qualified for an ambient operating

temperature range of –40°C to 150°C

The A1693 output is an open collector that requires a pull-up

resistor. Each time a new magnetic state is detected, the output

goes low for a pulse-width time that communicates a forward-

direction, reverse-direction, or non-direction.

The sensor IC is AEC-Q100 qualified for automotive

applications, and is provided in a lead (Pb) free 4-pin single

inline package (SIP) with 100% matte tin leadframe plating.

PACKAGE: 4-PIN SIP (SUFFIX K)
