A1569E LED Driver with Integrated Hall-Effect Switch
FEATURES AND BENEFITS
• 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 physical stress • Input pin for external LED driver control • Slew-rate-limited LED output drive for current transient suppression • Ruggedness and reliability □□Integrated voltage
