A80601 Datasheet High Power LED Driver

Manufacturer: Allegro MicroSystems

Datasheet Details

The A80601 is a multi-output LED driver for automotive applications such as exterior lighting, heads-up display, and mid-size LCD backlighting.

It implements a current-mode boost/SEPIC converter with gate driver for external N-channel MOSFET.

The A80601 provides four integrated current sinks driving up to 210 mA per string.
