3.1 Evaluation Kit Contents

The ULC1001-DRV290x EVM is not outfitted with any additional hardware, but TI recommends to purchase the USB2ANY for connecting the GUI to the computer. TI has open source design LCS prototypes that can be purchased to fully evaluate the ultrasonic lens cleaning technology. When using different lens covers, considering and updating the boost voltage and LC filter on the EVM is important. More information on TI lens cover prototypes and details regarding the EVM updates to be made can be found in the Mechanical Design Guides. Other lens cover systems can be tested using the ULC1001-DRV290X EVM as well.

The ULC1001-DRV290x EVM has two input power connectors, one screw down terminal block (J6) and one 2.5mm barrel jack (J4). The output is connected through the J5 terminal block at the bottom of the board. An on-board MSP430 controls four push buttons with default configurations and a USB2ANY can be connected through the J1 header.

Table 5-2 lists the descriptions for all connections, jumpers, and switches on the EVM.

Table 3-1 ULC1001-DRV290x EVM Port and Switch Descriptions
Port Description
J1 USB2ANY port compatible with the 10-pin cable that ships with the USB2ANY. Pin 6 is GND. Pin 9 is SCL. Pin 10 is SDA.
J2 Micro-USB port for MSP430.
J3 JTAG programmer for USB2ANY.
J4 Power Supply input barrel jack, 2.5mm. Input 9V-16V, 8A. (Use either J6 of J4).
J5 Output terminal block, possible output range of 0-250Vp, 3.5A, 10kHz-400 kHz depending on load and filter configuration. Terminal block rated for 300V, 15A.
J6 Power Supply input terminal block. Input 9V-16V, 8A. (Use either J6 of J4).
J7 Power connection between converters and the DRV290x device for 12V, GND, and PVDD.
J8 Pin header for disconnecting the MSP430 SCL connection.
J9 Power connection from converters to the ULC1001 and MSP430 for GND and 3.3V.
J10 Pin header for disconnecting the MSP430 SDA connection.
J11 UART connection to the MSP430.
S1 Power switch for entire EVM. Disconnects the input supply from the converter circuits.
S2 I2C address select switch. Pulls AD0 on ULC1001 to VDD or GND. Replacing R19 and R13 with 10kΩ resistors enables additional I2C addresses.
S3 Shutdown switch for ULC1001 (SDZ). SDZ is pulled low when switch S3 is pushed.
S4 Run Water mode continuously from MSP430.

2nd press stops the continuous Water mode.
S5 Run Auto mode continuously from MSP430. 2nd press stops the continuous Auto mode.
S6 Run Water mode from MSP430.
S7 Run Calibration from MSP430.
S8 BSL (Bootstrap Loader) for MSP430 programming.
