06XS3517
The 06XS3517 device is a five channel 12 V high side switch
module with integrated control and a high number of protective and
diagnostic functions. It is designed for automotive lighting and
industrial applications. The low R_DS(ON) channels (three 6.0 m, two
17 m) can control different types of lighting applications; bulbs,
Xenon-HID lights, and LEDs. Control, device configuration, and
diagnostics are performed through a 16-bit SPI interface (3.3 V or
5.0 V). When communication with the external microcontroller or VDD
is lost, the device enters a fail-safe operation mode, but remains
operational, controllable, and protected.
The channels are controlled by an external clock signal and allow
staggered switch-on delay, to improve EMC performances.
Programmable output voltage slew rates (individually programmable)
further helps improve EMC performance. To avoid shutting off the
device upon inrush current while still being able to closely track the
load current, a dynamic over-current threshold profile is featured. Load
current in each channel can be sensed. The duty cycle of the channels
can be controlled independently and the switching frequency of each
of them can be doubled. The 06XS3517 is housed in a non-leaded
Power QFN package with an exposed pad.
