ULN2003A

This reference design provides a flexible stepper motor system designed to drive up to two stepper motors: or 8 peripherals: while reducing the number of GPIOs needed from the host controller reducing overall cost. The system is suitable for applications requiring stepper motors or coils up to 50V: and a max current of 2.5A (with all channels  enabled). This design features multiple configurations for outputs: allowing multiple peripherals to be driven (i.e. 1 motor: 1 buzzer: 1 relay: and 2 LEDs). It is adaptable to automated louver control in Heating Ventilation and Air Conditioning (HVAC) systems as well as control of relays: buzzers: and LEDs. This concept could also be more broadly expanded to drive any number of channels for other building automation designs including louver control in smart ventilation systems: automated window blind tilting: as well as pan and tilt control for IP cameras.

The objective of the TIDA-00560 TI Design is to demonstrate a multi-channel LED driver as required in PLC I/O modules to indicate the status of several analog, digital input, and output channels. Important requirements for such a design like low static current, low component count, minimal PCB re

This reference design implements single-phase inverter (DC-AC) control using the C2000™ F2837xD and F28004x microcontrollers. Design supports two modes of operation for the inverter. First is the voltage source mode using an output LC filter. This control mode is typically used in uninterruptible power supplies (UPS). Second is grid connected mode with an output LCL filter: which is typically used in solar inverters. Firmware for the design is supported under the powerSUITE framework which enables adaptation using the Solution Adapter and enables tuning of the control loop using the Compensation Designer and SFRA. High-efficiency: low THD and intuitive software make this design attractive for engineers working on inverter design for UPS and alternative energy applications such as PV inverters: grid storage and micro grids.

This reference design implements safe brake control functionality in servo drives as per IEC EN 61800-5-2 by providing two channel output signals to control an external holding brake. The holding brake will be latched when the power supply is cut off and released when voltage is applied to the coil. This is accomplished by enabling/disabling the smart electronic load switches that supply power to the coil. This reference design also includes diagnostic features for detecting various faults: ensuring safe operation. TIDA-01600 uses the C2000 Launchpad to generate the brake control signals and to perform the diagnostics functionality.
