High Precision Industrial Hall Effect Sensor for 5V Applications

Product Brief
TLI496x-xM
High Precision Industrial Hall Effect Sensor for 5V Applications
TLI496x-xM is an integrated Hall effect sensor specially designed for highly accurate
applications. The sensor provides an easy-to-use and cost effective solution for position
sensing applications, requiring high temperature stability of the magnetic threshold.
Key Features
Target applications for the TLI496x-xM Hall switch family are all applications requesting
a precision Hall latch or Hall switch with an operating temperature from -40 °C to 125 °C.
By offering an excellent magnetic behavior Infineon’s switches are ideally suited for:
„„ Index counting applications with a pole wheel
„„ Rotor position detection (BLDC motors)
„„ Open/close detection
„„ Low current consumption 1.4 mA
„„ 3.0 V to 5.5 V operating supply
voltage
„„ ESD protection 4 kV HBM
„„ Active error compensation
(chopped)
„„ High stability of magnetic
thresholds
„„ Low jitter (typ. 0.35 µs)
Responding to the market requirements of industrial applications the TLI496x-xM provides a cost optimized solution with very low current consumption (1.4 mA) and superior
ESD protection (up to 4 kV HBM). The sensor family enables the design of highly power
efficient and robust systems in line with a very low failure rate in production.
Furthermore it supports applications requiring operating supply voltage from 3.0 V to
5.5 V. The extremely small SOT23 SMD package (just 2.9 x 1.3 x 1.0 mm) is dedicated for
the design of very small and compact application circuits.
To enable our customers’ systems to fulfill the highest quality standards and various
environmental regulations: the SOT23 package is halogen free, RoHs compliant and
JESD47 qualified.
Applications
„„ Brushless DC motors for commutation, e.g. e-bike, cooling fans for PC
„„ Power closing in home automation, e.g. sun-blind, garage door
„„ Open/close detection, e.g. in white goods or home security systems

Infineon’s latest TLI496x-xM products are dedicated for industrial applications requiring an operating supply voltage from 3.0 V to 5.5 V.
The family comprises integrated Hall effect sensors, with a latch
or Hall switch characteristic and highly accurate switching thresholds for operating temperature up to 125 °C.
The chopped Hall IC switch comprises a Hall probe, bias generator, compensation circuits, oscillator and output transistor.
The bias generator provides currents for the Hall probe and the
active circuits.

The temperature behavior is stabilized by compensation circuits.
The active error compensation (chopping technique) rejects offsets in the signal path and minimizes the influence of mechanical
stress to the Hall probe caused by molding and soldering processes or other thermal stress in the package. The chopped measurement principle together with the threshold generator (comparator
with hysteresis), and the comparator ensures highly accurate and
temperature stable magnetic thresholds.
