# LL204 Dual Output Flasher

## Description
️· Dual output stages flasher for relay driver applications (e.g., automotive lighting).
️· Controls vehicle lights independently (left/right sides).
️· Simplifies hazard switch construction with a separate hazard warning input.
️· Increases flash frequency (2:1 ratio) to indicate lamp failure.
️· Low current consumption allows direct connection to the battery.

## Features
️· Temperature & voltage compensated flashing frequency.
️· Lamp fault indication via frequency doubling.
️· High current relay driver outputs with low saturation voltage.
️· Minimum lamp load: ≥ 1W.
️· Low EMI sensitivity.
️· Extremely low current consumption (<10μA).
️· Reverse polarity protection.
️· Three control inputs: left, right, hazard warning.
