2.4 Setup for Different UCC57108 Variants

The UCC57108EVM comes installed with the bipolar-voltage UCC57108B variant of the UCC57108 IC, and the EVM out-the-box is setup according to that variant. The UCC57108 family of devices comes in two more variants: the UCC57108C, which has split output, and the UCC57108W, which has enable function.

The UCC57108EVM also supports the UCC57102 IC, which is the 12.5V UVLO version of the UCC57108 IC. The UCC57102 has the same variant types as the UCC57108, and the information in this section applies to the UCC57102 IC as well. See the UCC5710x-Q1 High-Speed, Low-Side Gate Driver With DESAT Protection For Automotive Applications data sheet for more information.

Because each UCC57108 variant has slightly different pinouts, the EVM has jumpers to support the different variants. Jumpers J2 and J3 allow the user to short or open between connectors depending on which variant is being used. Figure 3-1 shows how J2 and J3 must be configured with each UCC57108 variant. Do not short more than one connection on J2. If the user is using variants other than the UCC57108B, then desolder resistor R16.

In addition to jumpers J2 and J3, there is also an option to solder 0Ω jumper resistors (R10, R12, or R16) for a low-parasitic way to short connections. The EVM out-the-box supports the UCC57108B variant, which has R16 installed on the board. Resistors R10 and R12 are not installed. If you are using the other variants, you must desolder R16. Table 3-4 to Table 3-6 showcases a guide to soldering or desoldering the 0Ω jumper resistors for each UCC57108 variant.
