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.”
