A1569E Product details

Description

The A1569E is a highly integrated solution that combines a Hall-effect switch with a linear, programmable current regulator, providing up to 150 mA to drive one or more LEDs.

Features

Linear LED drive current ≤150 mA set by an external reference resistor.
High sensitivity, omnipolar Hall-effect switch for LED on/off control.
Low component count for small size and ease of design.
Elegant fade-in/fade-out effects with adjustable duration (optional).
Low dropout voltage and low supply current.
Chopper-stabilized Hall switch.
Low switchpoint drift over temperature.
Insensitivity to phys.
