NOTES:
4. Voltage measured with respect to SGND
5. VIN supplies the power FETs. VDD supplies the controller. VIN can be tied to VDD. For VDD ≤ 5.5V, VDD should be tied to VR.
6. Includes ±10% margin limits.
7.
θJA 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
θJC, the “case” temperature is measured at the center of the package underside.
Electrical Specifications VDD= 12 V, TA = -40°C to +85°C unless otherwise noted. Typical values are at TA = 25°C. Boldface limits apply
over the operating temperature range, -40°C to +85°C.
