ASL3417SHN规格书详情
General description
The ASL3417SHN has a hysteretic buck DC-to-DC topology. With input voltages from
10 V to 80 V, it allows maximum flexibility on output voltages for each channel, enabling
applications with up to 20 LEDs. It also provides an output current of up to and above
1.5 A per channel.1 Furthermore, two output channels can be connected together to
provide an even higher current. It drives an external high-side N channel MOSFET from
an internally regulated adjustable supply. The ASL3417SHN buck driver gives a flexible
system design which can be used to drive three LED strings with the same architecture.
The ASL3417SHN provides an SPI interface for extensive control and diagnostic
communication with an external microcontroller. Furthermore, the ASL3417SHN
integrates a customer programmable Limp-home mode. It allows configurable operation in
Limp-home mode in case SPI communication with the microcontroller has failed.
The ASL3417SHN offers an adjustable hysteresis for optimizing external components as
well as minimizing LED current ripple.
In addition, the ASL3417SHN provides an output voltage of up to 70 V. It has a
measurement capability that can be used to identify LED open or short circuit conditions.
The microcontroller can read this voltage and use it to detect open or short circuit
conditions. There are also additional diagnostic features such as current reached status.
Additional features include input under-voltage lockout and thermal shutdown when the
junction temperature of the ASL3417SHN exceeds +175 C.
It is housed in a very small HVQFN32 pin package with an exposed thermal pad and is
designed to meet the stringent requirements of automotive applications. It is fully AEC
Q100 grade 1 qualified. It operates over the ambient automotive temperature range of
40 C to +125 C.
