Micropower Omnipolar
Digital Hall-Effect Sensor ICs
DESCRIPTION
The SL353 Series sensor ICs (Integrated Circuits) are small,
versatile, digital Hall-effect devices operated by the magnetic
field from a permanent magnet or an electromagnet. These
sensitive devices are designed to meet a wide range of
potential applications with low power requirements.
The SL353 Series responds to either a North or South pole,
meaning that they do not require the magnet polarity to be
identified, providing an easier installation and potentially
reducing system cost.
These low-power sensing devices use BiCMOS (Bipolar
Complementary Metal Oxide Semiconductor) technology and a
timing circuit that turns the power on for only a short time
off for the rest of the period (duty cycle)
the average current consumption.
Both products can operate from a supply voltage as low as
2.2 V, promoting energy efficiency.
VALUE PROPOSITIONS
SL353LT
For device manufacturers who need ultra low power sensing
for battery-operated, mobile applications, Honeywell’s
SL353LT Omnipolar Hall-Effect Sensor IC provides an ultra
low power (1.8 μA, 2.8 Vdc) sensor IC and helps minimize
PCB (Printed Circuit Board) space, part count and cost for
the entire application.
Unlike other low power Hall-effect sensors, the SL353LT offers
ultra low power sensing with significantly lower noise
emissions and the ability to minimize PCB space and cost
for the entire application as demonstrated by a non-chopper
stabilized design, subminiature SOT-23 packaging,
omnipolar sensing, the shortest active mode time and
lowest average current in its class.
significantly reducing
it is
The push-pull output does not require a pull-up resistor and
can operate with very low current levels, potentially helping to
reduce cost and minimizing the total current consumption.
The SL353 Series is available in two duty cycle configurations
to accommodate a variety of application needs:
The SL353 Series has a typical operating point of ±60 Gauss
at 25 °C [77 °F].
These sensors are available in the subminiature SOT-23
surface mount package on tape and reel (3000 units per reel),
for use in automated pick-and-place component installation.
SL353HT
For device manufacturers who need to optimize the PC
board in energy efficient, “green” products with higher
switching frequency requirements, Honeywell’s SL353HT
Omnipolar Hall-Effect Sensor IC provides a low power sensor
IC that can be used in higher switching frequency
applications.
Unlike standard Hall-Effect sensors, the SL353HT offers the
ability to optimize the PCB in high switching frequency
applications as demonstrated by its low power (0.33 mA,
2.8 Vdc) use, high duty cycle (13% typ.) and subminiature
SOT-23 package size.
SL353HT: High duty cycle (13% typ.) for applications
requiring high switching speed and a lower current
(0.33 mA typ.) than standard Hall-effect sensor ICs.
SL353LT: Very low duty cycle (0.013% typ.), resulting in
extended battery life in applications requiring extremely low
current drain (1.8 µA typ.) and not requiring a high
switching speed.
