PRELIMINARY INFORMATION

(subject to change without notice)

April 23, 2002

PROGRAMMABLE, CHOPPER-

STABILIZED, HALL-EFFECT SWITCHES

The A3250 and A3251 are programmable switches that provide

tooth/valley recognition in large gear-tooth sensing, high-temperature

applications. Each sensor consists of a single element, chopper-

stabilized Hall-effect IC that can be programmed to the desired mag-

netic operate switch point (drastically reducing the effects of variations

found in a production environment), while the hysteresis remains fixed.

The small package can be easily assembled and used in conjunction

with a wide variety of gear/target shapes and sizes. The A3250 output

turns on in the presence of the programmed south-pole magnetic field

while the A3251 turns off with the programmed south-pole magnetic

field.

These sensor systems are ideal for use in gathering speed, position,

and timing information using gear-tooth-based configurations. They are

particularly suited to those applications that require accurate duty cycle

control or accurate edge detection. The lower vibration sensitivity also

makes these devices extremely useful for transmission speed sensing.

The first character of the part number suffix determines the device

operating temperature range. Suffix ‘J–’ is for the automotive and

industrial temperature range of -40°C to +115°C. Suffix ‘L–’ is for the

automotive and military temperature range of -40°C to +150°C. The

package is a three-lead ultra-mini-SIP for through-hole mounting

(suffix ‘–UA’). It is also available with lead forming for surface-

mount applications (suffix ‘–UA-TL’).

* Fault conditions that produce supply voltage

transients will be clamped by an internal Zener

diode. These conditions can be tolerated but

should be avoided.

† Internal current limiting is intended to protect

the device from output short circuits.

FEATURES AND BENEFITS

Chopper Stabilized for Extremely Low Switch-Point Drift and

Immunity to Mechanical Stress

Externally Programmed Switch Point

On-Chip Supply-Transient Protection

Output Short-Circuit Protection

Reverse Battery Protection

Wide Operating Voltage Range

Defined Power-On State

Always order by complete part number: the prefix 'A' + the basic four-digit

part number + a suffix to indicate operating temperature range (‘J’ or ‘L’) +

a suffix to indicate package style (‘UA’), e.g.,
