3 Description
The TMAG5253 is a low-power linear Hall effect
sensor that responds proportionally to magnetic flux
density. The device features an enable pin to enter
ultra-low power (nA) shutdown mode. The TMAG5253
features a fast start-up time (< 25μs and < 60μs)
designed for low-power position sensing applications.
The device is available in an industry-leading
1.54mm2 ultra-small footprint for space-constrained
applications. The device has a wide supply range and
can operate from 1.65V to 3.6V.
Magnetic flux perpendicular to the top of the package
is sensed by the device and the TMAG5253 is
available in two sensitivity polarity options: bipolar
and unipolar. North and south magnetic poles produce
unique voltages in the bipolar option and the unipolar
option is sensitive to either the south or the north
magnetic pole. The output changes linearly with the
applied magnetic flux density, and four sensitivity
(in bipolar) and one sensitivity (in Unipolar) options
enable maximal output voltage swing based on the
required sensing range.
The device uses a ratiometric architecture that can
eliminate error from VCC tolerance when the external
analog-to-digital converter (ADC) uses the same VCC
for the reference. Additionally, the device features
magnet temperature compensation to counteract the
magnetic sensitivity drifts across a wide –40°C to
125°C temperature range. The device also features
the ability to place the output in a high impedance
state during shutdown mode. This enables multiple
devices to be connected to a single ADC.
