ASL3417SHNY Description

Short technical summary and product information.

The ASL3417SHNY is an enhanced three-channel buck mode LED driver IC designed for automotive exterior and interior lighting applications. It utilizes a hysteretic buck DC-to-DC topology, accepting input voltages from 10V to 80V and providing an output current of up to 1.5A per channel. This IC supports up to three independent LED strings, offering flexibility in design. It features an SPI interface for control and diagnostics, along with a customer-programmable Limp-home mode for fault conditions.

 

The ASL3417SHN provides an adjustable hysteresis for optimizing external components and minimizing LED current ripple. It can drive up to 20 LEDs per channel and offers an output voltage of up to 70V. Diagnostic features include LED open or short circuit detection and current reached status. Additional protections include input under-voltage lockout and thermal shutdown at +175°C.

 

This LED driver IC is housed in a 32-HVQFN package with an exposed thermal pad, suitable for surface mounting. It operates within an ambient automotive temperature range of -40°C to +125°C and is AEC Q100 grade 1 qualified.
