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 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:

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.

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 it is

off for the rest of the period (duty cycle) significantly reducing

the average current consumption.

The SL353 Series has a typical operating point of ±60 Gauss

at 25 °C [77 °F].

Both products can operate from a supply voltage as low as

2.2 V, promoting energy efficiency.

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.

VALUE PROPOSITIONS

SL353HT

SL353LT

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.

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 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.

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.
