NOTES:
4. Voltage measured with respect to SGND
5. V IN supplies the power FETs. V DD supplies the controller. V IN can be tied to V DD . For V DD ≤ 5.5V, V DD should be tied to VR.
6. Includes ±10% margin limits.
7. θ JA is simulated in free air with device mounted on a four-layer FR-4 test board (76.2 x 114.3 x 1.6mm) with 80%-coverage, 2-ounce Cu on top and
bottom layers, plus two, buried, one-ounce Cu layers with coverage across the entire test board area. Multiple vias were used, with via
diameter = 0.3mm on 1.2mm pitch.
8. For θ JC , the “case” temperature is measured at the center of the package underside.
Electrical Specifications V DD = 12 V, T A = -40°C to +85°C unless otherwise noted. Typical values are at T A = 25°C. Boldface limits apply
over the operating temperature range, -40°C to +85°C.
