SB0800 Octal Valves and Pump Controller System on Chip
Analog Solutions—Robust, Reliable Performance SB0800 Octal Valves and Pump Controller System on Chip Overview Target Applications The Octal Valves and Pump Controller System on Chip (VAPS) consists of four low-side drivers • Industrial Controller regulated and four low-side drivers digitals, plus a high side to control a DC motor. This simple solution is suitable for loads with high inrush current and allows driving to high frequency (up to •Force 5 kHz). To use the chip, a simple serial peripheral interface (SPI) communication is needed. With • Spot Welding this communication, users can perform control and diagnostic functions directly on the chip. • Fluid Coating The device is designed for harsh environments, and it includes self-recovery features thanks to • Flight Simulator the embedded supervision that allows extensive safety monitoring. Furthermore, a predriver-safe • Temperature Control 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.” • Laser Cutting SB0800 Simplified Diagram implified Diagram • Bottle Moulding • Filling Pressure SB0800 VBAT External 5.0 Regulator DOSV VINT_A VINT_D VCC5 VCC5 P53_CFG VBAT VPWR VBAT RSTB SO SI CSB SCLK CP HD_D HD_G HD_S HS VBAT PD_D PD_G PD_S GND_D NC Solenoid Coil LSD5 LSD6 LSD7 LSD8 4 Example of 5V Application *This image represents a typical configuration MCU 3 GND_A LSD1 LSD2 LSD3 LSD4 GND_P0,1...4 Solenoid Coil • Brake Pressure Freescale: A Leader in Analog Solutions Typical Use Case Up to 30V DC Expanding on more than 30 years of innovation, Freescale is a leading provider of high-performance products that use 10µ 5V Voltage Regulator 220n Vcc3.3 Charge Pump CP 3.3V Voltage Regulator Faults Management & State Machine Vcc5 SMARTMOS technology combining digital, power and standard analog functions.
