analog, mixed-signal and power management mc16xsd200 dual 16 mohm high-side switch overview the mc16xsd200 device is part of a 36 v high-side switch product family with integrated control and a high number of protective and diagnostic functions. it is designed for industrial applications. the low r ds(on) channels (< 16 m) can control different load types, including bulb lamps, solenoids or dc motors. control, device configuration and diagnostics are performed through a 16-bit serial peripheral interface (spi), allowing easy integration into existing applications. both channels can be controlled individually by external or internal clock signals, or by direct inputs. using the internal clock allows fully autonomous device operation. programmable output voltage slew rates (individually programmable) help improve electromagnetic compatibility (emc) performance. target applications ? industrial (12 v and 24 v systems) ? halogen bulbs ? light-emitting diodes (leds) ? low-voltage industrial lighting ? dc motors simplified application drawing 0 & 8 9 ' ' & / 2 & . ) 6 % 6 & / . & 6 % 6 2 5 6 7 % 6 , , 1 , 1 & 6 1 6 * 1 ' 9 ' ' 9 3 : 5 + 6 + 6 / 2 $ ' , 2 6 & / . & 6 % 6 , , 2 6 2 , 2 , 2 $ ' * 1 ' / 2 $ ' 0 & 2 1 ) & 2 1 ) ) 6 2 % , 2 $ ' 6 < 1 & , 2 ; 6 ' 9 ' ' 9 3 : 5
a dynamic overcurrent threshold profile is utilized to avoid shutting off the device due to inrush current while still being able to closely track the load current. switching current of each channel can be sensed with a programmable sensing ratio. whenever communication with the external mcu is lost, the device enters a fail-safe operation modebut remains operational, controllable and protected. freescale: a leader in analog solutions expanding on more than 30 years of innovation, freescale is a leading provider of high-performance products that use smartmos technology combining digital, power and standard analog functions. freescale supplies analog and power management ics that are advancing the automotive, consumer, industrial and networking markets. analog solutions interface with real-world signals to control and drive for complete embedded systems. for more information, please visit freescale.com/analog freescale and the freescale logo are trademarks of freescale?semiconductor,?inc., reg. u.s. pat. & tm. off. smartmos is a trademark of freescale semiconductor, inc. all other product or service names are the property of their respective owners. ??2013?freescale?semiconductor,?inc. document number: mc16xsd200fs rev 1 product features and benefits features benefits two fully protected 16 m (@ 25 c) high-side switches offers an intelligent high-side switch for 24 v industrial applications up to 3.0 a steady state current per channel allows decentralized lighting management (autonomous operation) separate bulb and dc motor latched overcurrent handling provides a high number of protective and diagnostic functions individually programmable internal/external pwm clock signals allows to drive bulb lamps (tungsten filament), led lights and dc motors overcurrent, short-circuit and overtemperature protection with programmable auto-retry functions guarantees full functional and electrical compatibility between family members accurate temperature and current sensing offers a 16-bit spi interface for daisy chaining multiple devices open-load detection (channel in, off and on states) and led applications (7.0 ma typical) allows multiple channel and device current sensing with only one precision resistor normal operating range: 8C36 v, extended range: 6C58 v 3.3 and 5.0 v compatible 16-bit spi port for device control, configuration and diagnostics at rates up to 8.0 mhz documentation freescale document number title description mc16xsd200 dual 16 m high-side switch data sheet sg1002 analog product selector guide selector guide sg200 analog and power management industrial selector guide selector guide an2467 power quad flat no-lead package application note an4473 compact thermal model application note application note AN4474 emc and fast transient pulses performances application note application note an4516 ibis model application note application note performance performance typical values outputs 2 r ds(on) at 25 oc dual 16 m operating voltage 8 to 36 v extended operating range 6 to 58 v peak current 38.5 a esd 8.0 kv power i/os 2.0 kv digital i/os development tools part number typical values kit20xs4200evbe evaluation board featuring the mc20xs4200 24-pin pqfn (12 x 12 mm) 98asa00428d
