A80602 - High Power LED Driver

Description

The A80602 is a multi-output LED driver for automotive applications such as exterior lighting, heads-up display, and midsize LCD backlighting.

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

Features

  • Automotive AEC-Q100 qualified.
  • Enhanced fault handling for ASIL B system compliance.
  • Wide input voltage range of 4.5 to 40 V for start/stop, cold crank, and load dump requirements.
  • Operate in Boost or SEPIC mode for flexible output.
  • Gate driver for external MOSFET to deliver higher output power.
  • Six integrated LED current sinks, up to 140 mA each.
  • Boost switching frequency synced externally or programmed from 260 kHz to 2.3 MHz.
