MC12XSFD3

NXP Semiconductors Data Sheet: Advance Information Document Number: MC12XSFD3 Rev. 1.0, 8/2016 Penta 40 mOhm high-side switch The 12XSF is the latest SMARTMOS achievement in DC motors and lighting drivers. It belongs to an expanding family that helps to control and diagnose incandescent lamps and 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 in an End of Life Vehicles directive compliant package. Features Penta 40 mΩ high-side switches with high transient current capability 16-bit 5.0 MHz SPI control of overcurrent profiles, channel control including PWM duty cycles, output-ON and -OFF OpenLoad detections, thermal shutdown and prewarning, and fault reporting Output current monitoring with programmable synchronizati...
