MC07XSF517
Triple 7.0 mOhm and Dual 17 mOhm
High-Side Switch
Overview
The MC07XSF517 is the latest achievement in DC motors 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 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 facilitates ECU design due to compatible MCU
software and PCB footprints for each device variant.
This product is packaged in a Pb-free power-enhanced SOIC package with an exposed pad.
