0, 9/2013 Penta 17 mOhm High Side Switch The 17XSF500 is the latest achievement in DC motor and lighting drivers.
It belongs to an expanding family to control and diagnose various types of loads, such as incandescent lamps or light-emitting diodes (LEDs) with enhanced precision.
It combines flexibility through daisy-chainable SPI 5.
0 MHz, extended digital and analog feedbacks, safety and robustness.
Output edge shaping helps to improve electromagnetic performance.
To avoid shutting off the device upon inrush current, while still being able to closely track the load current, a dynamic overcurrent threshold profile is featured.
Current of each channel can be sensed with a programmable sensing ratio.
Whenever communication with the external microcontroller is lost, the device enters a Fail operation mode, but remains operational, controllable, and protected.
This new generation of high side switch products family facilitates ECU design thanks to compatible MCU software and PCB foot print for each device variant.
This family is packaged in a Pb-free power-enhanced SOIC package with exposed pad which is End of Life Vehicles directive compliant.
This device is powered by SMARTMOS technology.
