Document Number: MC20XS4200 Freescale Semiconductor Rev. 5.0, 11/2013 Advance Information Dual 24 V, 20 mOhmHigh Side 20XS4200 Switch The 20XS4200 device is part of a 24 V dual high side switch product family with integrated control, and a high number of protective and diagnostic functions. It has been designed for truck, bus, and industrial HIGH SIDE SWITCH applications. The low R channels (<20 m ) can control different DS(ON) load types bulbs, 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. This device is powered by SMARTMOS technology Both channels can be controlled individually by external/internal clock signals, or by direct inputs. Using the internal clock allows fully autonomous device operation. Programmable output voltage slew- rates (individually programmable) helps improve electromagnetic compatibility (EMC) 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. Switching current of each channel can be sensed with a programmable sensing ratio. FK SUFFIX (PB-FREE) Whenever communication with the external microcontroller is lost, the 98ASA00428D device enters a Fail-safe operation mode, but remains operational, 23 PIN PQFN (12 X12 mm) controllable, and protected. Features Two fully-protected 20 m ( 25 C) high side switches Up to 3.0 A steady-state current per channel Separate bulb and DC motor latched overcurrent handling Individually programmable internal/external PWM clock signals Overcurrent, short-circuit, and overtemperature protection with programmable autoretry functions Accurate temperature and current sensing OpenLoad detection (channel in OFF and ON state), also for LED applications (7.0 mA typ.) Normal operating range: 8.0 - 36 V, extended range: 6.0 - 58 V 3.3 V and 5.0 V compatible 16-bit SPI port for device control, configuration and diagnostics at rates up to 8.0 MHz V V V DD DD PWR 20XS4200 VDD VPWR I/O CLOCK I/O FSB SCLK SCLK HS0 CSB CSB LOAD SI SO MCU I/O RSTB SO SI HS1 I/O IN0 LOAD M I/O IN1 CONF0 CONF1 I/O FSOB A/D SYNC A/D CSNS GND GND Figure 1.

Recommended for all new designs 2. Version B and BA devices can support negative voltage battery and ground loss down to -32V, the overcurrent profile can be selected by the SPI. It is no longer recommended to disable the off-state OpenLoad for the HS1 output in parallel mode, errata sheet MC24XS4ER is no longer valid. 3. Version BA devices have faster slew rates to reduce switching losses. 20XS4200 Analog Integrated Circuit Device Data 2 Freescale Semiconductor
