MC08XS6421EK

NXP Semiconductors Document Number: MC12XS6D4 Rev. 6.0, 1/2021 Data sheet: Technical Data Dual 8.0 mOhm and dual 21 mOhm MC08XS6421BEK MC08XS6421CEK high-side switch MC08XS6421DEK The 12XS6 is the latest SMARTMOS achievement in automotive lighting drivers. It belongs to an expanding family that helps to control and diagnose incandescent QUAD HIGH-SIDE SWITCH lamps and light-emitting diodes (LEDs) with enhanced precision. It combines flexibility through daisy chainable SPI 5.0 MHz, extended digital and analog feedback, 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 BEK and DEK SUFFIX CEK SUFFIX operation mode, but remains operational, controllable, and protected. (PB-FREE) (PB-FREE) This new generation of high-side switch products family 12XS6 facilitates ECU 98ASA00368D 98ASA00894D design due to compatible MCU software and PCB foot prints for each device 32-PIN SOICW-EP 32-PIN SOICW-EP variant.
