AD8240 - LED Driver/Monitor

Datasheet Summary

Description

The AD8240 LED driver/monitor, in combination with an external transistor, supplies a constant 12 V to drive LED lamps.

This allows cost-effective LED lamp monitoring and short-circuit protection.

The output is regulated at 12 V when the supply voltage is between 12.5 V and 27 V.

Features

  • PWM input for LED brightness control Open LED detection Latch-off overcurrent protection Constant voltage regulated output Supply range: 9 V to 27 V Regulated voltage range: 12.5 V to 27 V Operating current: 300 µA Shutdown current: 10 µA Temperature range.
  • 40°C to +125°C 8-lead MSOP package.
