AH1898 Product details

Description
The AH1898 is a micropower magnetic range selectable (Bop/Brp) 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 support battery powered equipment and low voltage microcontrollers, the AH1898 can operate over the supply range of 1.6V to 3.6V and uses a hibernating clocking system to minimize the power consumption. The average supply current is only 4.3µA typical at 1.80V. The AH1898 has an 8kV ESD rating on the supply and output pins. To minimize PCB space the AH1898 is packaged in the small CSP package (0.81mm x 0.81mm typical).

Features
 • Omnipolar Operation (North or South pole)
 • Programmable Operate and Release Points
 • Supply Voltage of 1.6V to 3.6V
 • Micropower Operation
 • Chopper Stabilized Design Provides
    ◾ Superior Temperature Stability
    ◾ Minimal Switch Point Drift
    ◾ Enhanced Immunity to Physical Stress
 • No External Pull-up Resistors Required
 • Good RF Noise Immunity
 • -40°C to +85°C Operating Temperature
 • 8kV Human Body Model ESD Capability
 • Miniature U-WLB0808-4 (CSP 0.81mm x 0.81mm typical)
 • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
 • Halogen and Antimony Free. “Green” Device (Note 3)

Applications
 • Open and Close Detect for Cellular Phones
 • Holster or Cover Detect for Cellular Phones and Tablet PCs
 • Cover or Display Switch in Portable PCs
