NXP Semiconductors Document Number: MC22XS4200 Rev. 5.0, 6/2018 Data Sheet: Advance Information Dual 24 V, 22 mOhm high-side switch 22XS4200 The 22XS4200 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 is designed for truck and bus applications. The low R channels (<22 m) DS(on) can control different load types bulbs, solenoids, or DC motors. Control, device configuration, and diagnostics are performed through a 16-bit serial peripheral HIGH-SIDE SWITCH 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. Whenever communication with the external microcontroller is lost, the device BEK SUFFIX (PB-FREE) CEK SUFFIX (PB-FREE) enters a Fail-safe operation mode, but remains operational, controllable, and 98ASA00894D 98ASA00368D protected. 32 PIN SOIC (10 mm X 11 mm) 32 PIN SOIC (10 mm X 11 mm) Features Two fully-protected 22 m (at 25 C) high-side switches Applications Up to 4.2 A steady state current per channel Truck, bus and 24 V transportation systems Separate bulb and DC motor latched overcurrent handling Resistive, capacitive, and inductive loads Individually programmable internal/external PWM clock signals Overcurrent, short-circuit, and overtemperature protection with programmable autoretry functions Accurate temperature and current sensing Open load detection (channel in OFF and ON state), also for LED applications (7.0 mA typ.)
