Infusion Pump Background

Infusion Pumps are used to control medicine and fluids delivered to patients.An Infusion pump usually includes a fluid reservoir, an electro mechanical assemble for controlling fluid flow and catheter system for transferring fluids to the patient.Accurate flow control is critical.PSoC interfaces with sensors in the infusions pump to monitor parameters like pressure or force (fluid flow), temperature, air in-line and provide outputs to control fluid metering through a valve or motor and to identify an alarm condition.PSoC product solutions can also provide direct LCD drive and control, key pad or touch screen interface, power management and USB or RS-232 communication.


PSoC programmable analog & digital resources integrate everything shown in light blue below.Click on the colored blocks to view or sample the recommended PSoC Components.


The flexibility of PSoC allows you to customize each colored block, or PSoC Component, to meet your design requirements through the easy-to-use PSoC Creator Software IDE. These Components are available as pre-built, pre-characterized IP elements in PSoC Creator.

Design Considerations

PSoC® 3 and PSoC 5 provide a scalable platform which integrates all the required circuitry to provide a configurable Infusion Pump in a single chip, including:

 • High precision Analog front end, including a 0.1% accurate Voltage reference and up to 20 bits of resolution
 • Circuitry for controlling the Relay Valve for controlling the flow rate and flow uniformity
 • LCD direct drive and control
 • Power management capabilities including Battery Charging and Protection, Fuel Gauge, and Voltage Sequencing / Monitoring.
 • CapSense fully integrated for buttons
 • Communications including FS USB and RS-232
 • On chip EEPROM



  • The CY8CKIT-001 PSoC® Development Kit (DVK) provides a common development platform where you can prototype and evaluate different solutions using any one of the PSoC 1, PSoC 3, PSoC 4, or PSoC 5 architectures.

  • Cypress's PSoC programmable system-on-chip architecture gives you the freedom; to not only imagine revolutionary new products, but the capability to also get those products to market faster than anyone else.Explore PSoC 3's precision analog capabilities through the on board 20-bit Delta Sigma ADC used to measure voltage ranges between -30 V and 30 V.

  • The CY8CKIT-029 PSoC® LCD Segment Drive Expansion Board Kit allows you to evaluate PSoC's LCD drive capability using LCD segment component in Cypress's PSoC Creator™.
