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 (< 25 μs) designed for
low-power position sensing applications. The device
is available in an industry-leading 1.54-mm2 ultrasmall
footprint for space-constrained applications. The
device has a wide supply range and can operate from
1.65 V to 3.6 V.
Magnetic flux perpendicular to the top of the package
is sensed by the device and the TMAG5253 is
available in bipolar sensitivity polarity option, where
the north and south magnetic poles produce unique
output voltages. The output changes linearly with
the applied magnetic flux density, and four sensitivity
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 its 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.
