MC17XSF500
Penta 17 mΩ High-Side Switch
Overview
The MC17XSF500 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 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 utilized. 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 facilitates ECU design with its
compatible MCU software and PCB footprint for each device variant.
This product is packaged in a Pb-free, power-enhanced SOIC package with exposed pad.
