Dual 24 V, 20 mOhm High Side 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 applications. The low RDS(ON) channels (<20 mΩ) can control different 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. 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 compatability (EMC) performance. To avoid shutting off the device upon inrush current, while still being able to closely track the load current, a dynamic over-current 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 enters a Fail-safe operation mode, but remains operational, controllable, and protected. Features • Two fully-protected 20 m Ω (@ 25 °C) high side switches •Up to 3.0 A steady-state current per channel • Separate bulb and DC motor latched over-current handling • Individually programmable internal/external PWM clock signals • Over-current, short-circuit, and over-temperature 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.) • 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 Figure 1.
