3425
DUAL, CHOPPER-STABILIZED, ULTRA-SENSITIVE,
BIPOLAR HALL-EFFECT SWITCH
The A3425LK dual Hall-effect switch is an extremely
temperature-stable and stress-resistant sensor especially suited for
use in
digital-encoder systems in the harsh environments of automotive or
industrial applications
over extended temperature ranges to +150擄C.
Superior high-temperature performance is made possible through
dynamic offset cancellation, which reduces the residual offset voltage
normally caused by device overmolding, temperature dependencies, and
thermal stress.
This device also eliminates the major manufacturing
hurdles encountered in fine-pitch direction-detection applications,
namely maintaining accurate mechanical location between the two active
Hall elements. Here, the two Hall elements are photolithographically
aligned to better than 1
碌m,
as contrasted with 100
碌m
or worse me-
chanical location tolerance when manufactured discretely. The
A3425LK is an ultra-sensitive device optimized for use with high-
density ring magnets.
The device includes on a single silicon chip a voltage regulator, two
independent
chopper-stabilized Hall-voltage generators , two small-
signal amplifiers, two Schmitt triggers, and two short-circuit protected
open-collector outputs to sink up to 30 mA each. An on-board regulator
permits operation with supply voltages of 3.3 to 26.5 volts. With
suitable output pull ups, it can be used directly with bipolar or MOS
logic circuits.
The A3425LK dual Hall-effect switch is supplied in a 4-pin plastic
SIP for operation over a temperature range of -40擄C to +150擄C. A
similar device, with on-chip logic processing specifically for direction
detection applications, in a 5-pin SIP, is the A3422LKA.
