Hall-Effect Latch for High Temperature Operation

FEATURES AND BENEFITS

DESCRIPTION

▪ Symmetrical switchpoints

▪ Superior temperature stability

▪ Operation from unregulated supply

▪ Open-drain 25 mA output

▪ Reverse battery protection

▪ Activate with small, commercially available

permanent magnets

▪ Solid-state reliability

▪ Small size

▪ Resistant to physical stress

These Hall-effect latches are extremely temperature-stable

and stress resistant sensor ICs especially suited for operation

over extended temperature ranges to 150°C. Superior high-

temperature performance is made possible through a novel

Schmitt trigger circuit that maintains operate and release point

symmetrybycompensatingfortemperaturechangesintheHall

element.Additionally,internalcompensationprovidesmagnetic

switchpoints that become more sensitive with temperature,

henceoffsettingtheusualdegradationofthemagneticfieldwith

temperature.Thesymmetrycapabilitymakesthesedevicesideal

for use in pulse-counting applications where duty cycle is an

important parameter. The three basic devices (A1225, A1227,

and A1229) are identical except for magnetic switchpoints.

▪ Enhanced ESD structures result in 8 kV HBM ESD

performance without external protection components

▪ Internal protection circuits enable 40 V load dump

compliance without external protection components

Eachdeviceincludesonasinglesiliconchipavoltageregulator,

Hall-voltage generator, temperature compensation circuit,

signal amplifier, Schmitt trigger, and a buffered open-drain

output to sink up to 25 mA. The on-board regulator permits

operation with supply voltages of 3.8 to 24 V.

PACKAGES:

Not to scale

The first character of the part number suffix determines the

device operating temperature range. Suffix L is for –40°C to

150°C. Two package styles provide magnetically optimized

packages for most applications. Suffix LH is a 3-pin SOT23W

surface-mount package; suffix UAis a 3-pin ultramini SIP for

through-hole mounting. The packages are lead (Pb) free with

100% matte-tin leadframe plating.
