Octal Valve Controller System on Chip
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
The NXP® MC34SB0800 Octal Valve and Pump Controller System on Chip consists of four low-side drivers regulated and four low-side drivers digitals, plus a high side to control a DC motor.
- Suitable for loads with high inrush current and allows driving to high frequency (up to 5 kHz)
- With SPI communication, you can perform control and diagnostic functions directly on the chip
- Designed for harsh environments and includes self-recovery features due to the embedded supervision that allows extensive safety monitoring
- A predriver MOSFET increases safety by turning off all valves in the event of any issue
- Ideal solution to drive hydraulic or pneumatic valves without "smart electronics"
- Processor Expert® component Valve Driver and Embedded Software Valve Driver enables rapid embedded application development.
Product Details
Features
Supply Voltage
- 6 V (Min), 36 V (Max)
Low Side Drivers (x8)
- Four low side drivers regulated up to 2.25 A
- +/-2.0% precision reachable with calibration
- Four low side drivers PWM up to 5 kHz with a maximum current capability up to 5 A
- All low side drivers are integrated to save PCB space
High Side Pre-Driver
- Allows to control a DC motor pump up to 500 Hz
High Side Pre-Driver Fail Safe Switch
- Safe MosFet turned off all the valves and the motor in case of issues
10-Bit ADC
- ADC can monitor external or internal signals to enhance the control unit safety level
Embedded Supervision
- Watchdog
- Under-voltage, over-voltage, clock fail detection
- Open load, short circuit, over temperature detection on each low side
- Vds monitoring of each low side driver in real time
- Over current and over temperature detection on the high side pre-driver
Serial Peripheral Interface (SPI)
- Only one SPI is needed to control the device
- MCU sent only once the current or the duty-cycle targeted through the SPI
- MCU does not need to generate PWM signals at high frequency
- Interface and input control
