Robust, reliable analog solutions SB0800 Octal Valves and Pump Controller System on Chip The octal valves and pump controller system on chip (VAPS) consists of four regulated low-side drivers and four low-side drivers digitals, plus a high-side to control a DC motor. TARGET APPLICATIONS Medical }} Oxygen concentrators }} Medical test equipment }} Dialysis machines }} Blood pressure Commercial }} 3D printers }} Soda dispensers Industrial }} Heavy equipment and construction machinery }} Fork lifters }} Water control system for irrigation (connected to farm tractor) }} Food control in animal farm This simple solution is suitable for loads with high inrush current and allows driving to high frequency (up to 5 kHz). To use the chip, a simple serial peripheral interface (SPI) communication is needed. With this communication, users can perform control and diagnostic functions directly on the chip. The device is designed for harsh environments, and it includes self-recovery features thanks to the embedded supervision that allows extensive safety monitoring. Furthermore, a predriver-safe MOSFET increases safety by turning off all valves in the event of any issue. This system on chip is the perfect solution to drive hydraulic or pneumatic valves without “smart electronics.” DOCUMENTATION SB0800 DIFFERENTIATION Document Number Title MC34SB0800 Octal Valve and Pump Controller System on Chip Data sheet SG1002 Analog Product Selector Guide Selector guide SG200 Industrial Product Selector Guide NXP: A LEADER IN ANALOG SOLUTIONS Description Selector guide Features Benefits Industry/Voltage Supports the industrial industry with voltage ranges from 6 to 36 V Low RDS(on) for valve drivers in thermally enhanced package Best thermal efficiency Up to 8 LSD integrated into a LQFP 10 x10 64-pin package Best PCB space saving Switch-off energy drained by digital valves driver No freewheeling diode needed Built-in close loop control for regulated valves Only targetted value needs to be sent by SPI; error is reported when regulated current cannot be reached Accurate current regulated valves driver +/- 2.0% precision reachable without external discrete components and with calibration Safe MOSFET turned off all the valves in case No external circuitry needed to achieve full safe valve operation of issues Expanding on more than 30 years of MCU does not need to generate PWM signals at high innovation, NXP is a leading provider All actuators controllable through SPI frequency; MCU only sends targeted duty cycle through SPI of high-performance products that use ADC can monitor external or internal signals to enhance the 10-bit analog-to-digital converter SMARTMOS technology combining control unit safety level digital, power and standard analog Full control for system Digital diagnostics by SPI functions.
