Smart brake control and diagnostics reference design for servo drives and robotics
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.

Single-phase inverter reference design with voltage source and grid connected modes
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.

Configurable Stepper Driver for HVAC Louver and Motor Control Reference Design
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.

ULN2003A Frequently Asked Questions (FAQ)
-
The maximum current that can be sunk by each output of the ULN2003A is 500mA. However, it's recommended to derate the current to 350mA or less to ensure reliable operation and to prevent overheating.
-
Yes, the ULN2003A can be used to drive inductive loads like relays or solenoids. However, it's essential to add a freewheeling diode across the load to prevent back-EMF from damaging the driver. Additionally, ensure that the output current and voltage ratings are not exceeded.
-
To calculate the power dissipation of the ULN2003A, you need to consider the voltage drop across the output transistors and the current being sunk. The power dissipation can be calculated using the formula: Pd = (Vcc - Vout) x Iout. Ensure that the calculated power dissipation is within the recommended maximum power dissipation rating of 1.5W per output.
-
Yes, the ULN2003A can be used to drive LEDs. However, ensure that the LED current is within the recommended output current rating of the driver. Also, consider adding a current-limiting resistor in series with the LED to prevent excessive current.
-
The minimum input voltage required for the ULN2003A to function properly is 2.4V. However, it's recommended to use a minimum input voltage of 3V to ensure reliable operation and to prevent false triggering.
