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.
Features
