AH1902

HIGH SENSITIVITY MICROPOWER

OMNIPLOAR HALL-EFFECT SWITCH

Description

Pin Assignments

The AH1902 is a high sensitivity micropower Omnipolar Hall effect

switch IC with internal pull up and pull down capability. Designed for

portable and battery powered consumer equipment such as cellular

phones and portable PCs to office equipment, home appliances and

industrial applications, the average supply current is only 4.3uA at

1.8V. To support potable equipment the AH1902 can operate over the

supply range of 1.6V to 3.6V and uses a hibernating clocking system

to minimize the power consumption. To minimize PCB space the

AH1902 is available in small low profile X1-DFN1216-4 and X2-

DFN2015-6 packages.

The output is activated with either a north or south pole of sufficient

magnetic field strength. When the magnetic flux density (B)

perpendicular to the package is larger than operate point (Bop), the

output will be turned on (pulled low) and held until B is lower than

release point (Brp).

Features

Applications

•

Omnipolar Operation (North or South Pole)

Supply Voltage of 1.6V to 3.6V

Minimal Switch Point Drift

Level, Proximity and Position Switches

Contact-Less Switches in Home Appliances and Industrial

Applications

Enhanced Immunity to Physical Stress

•

No External Pull-up Resistors Required

Good RF Noise Immunity

-40°C to +85°C Operating Temperature

High ESD capability of 8kV (Human Body Model)

Small Low Profile X1-DFN1216-4 and X2-DFN2015-6 Packages

Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

Halogen and Antimony Free. “Green” Device (Note 3)

Notes:

1. EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. All applicable RoHS exemptions applied.

2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"

and Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and

<1000ppm antimony compounds.

Typical Applications Circuit

Note:

4. C_INis for power stabilization and to strengthen the noise immunity, the recommended capacitance is 100nF typical and should be placed as close to

the supply pin as possible.
