CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
9. Voltage measured with respect to SGND.
10. 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.
11. Includes ±10% margin limits.
12. 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, 2oz 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.
13. For θ JC , the “case” temperature is measured at the center of the package underside.
Electrical Specifications V DD = 12V, 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.
