Microchip medical MEMS micro pump products designed for drug delivery applications

image of Microchip's Medical MEMS Micro Pump DesignsMicrochip has reference designs targeted for drug delivery applications. MEMS piezoelectric micro pumps offer an attractive alternative to standard pumps that have traditionally been used in precision-controlled drug delivery devices. MEMS piezoelectric micro pumps offer the benefits of being small, lightweight, low power, low cost, and accurate. Micro pumps are now being used for applications such as transdermal insulin delivery, antithrombogenicity blood transportation, injection of glucose for diabetes patients, administration of neurotransmitters to neurons, and for chemical/biological sensing. Microchip’s medical MEMS micro pump demonstration board shows a unique implementation for cost-effective drug delivery devices. The integrated Core Independent Peripherals (CIP) on Microchip’s PIC16F1719 8-bit MCU significantly offload the MCU’s core in handling the control functions of a piezoelectric micro pump-based drug delivery device.

Microchip’s MCUs with CIP are designed to handle tasks independently with no code or supervision from the MCU’s core during operation. Using CIP can shorten the development time of complex control systems, reduce the design’s component count, board size, and power consumption, as well as give users the flexibility to innovate. The high-voltage driver functions are handled by Microchip’s HV9150 step-up DC/DC controller and the HV513 high-voltage push-pull driver ICs. The HV9150 converts the battery’s low supply voltage to a 250 V high supply voltage. The HV513 driver IC provides high-voltage unipolar push-pull output to actuate the piezoelectric micro pump.
