AH1815 – Ultra-Low Sensitivity,
Micropower, Omnipolar, Hall-Effect Switch
The AH1815 is an ultra-low
sensitivity, micropower,
omnipolar hall-effect switch IC,
designed for portable and
battery-powered consumer
equipment, home appliances
and industrial applications.
Based on two hall-effect plates
and chopper- stabilized
architecture, the AH1815
provides a reliable solution
over the whole operating
range.
AH1815 has been optimized to
operate over the supply range
of 2.5-5.5V and use a
micropower sleep function to
give an average supply current
of only 8µA.
AH1815 has an open-drain
output for flexibility and is
available in industry standard
SC59. (A small low-profile
SOT553 and a through-hole
SIP-3 package will be added
later in the year.)
The Diodes’ Advantage
The AH1815 provides a small and simple contactless switch solution
for battery powered consumer to industrial applications.
Omnipolar with operate point options and flexible output structure
-
Operates with either a North or South pole
-
Ultra low sensitivity with typical operate points: 395G
- Open drain for flexible pull-up strength
Designed for battery powered consumer to industrial equipment
-
Supply voltage designed optimized 2.5V to 5.5V
- Micropower operation with an average supply current of 8µA at 3V
High performance and reliability
- High sensitivity with tight operating window (less magnetic spread)
- Chopper stabilized design to provide minimal switch point drift and
superior temperature stability
- Operating temperature range -40
o
C to +125
o
C
