The A4985 is supplied in three surface mount packages: two QFN
packages, the 4 mm × 4 mm, 0.75 mm nominal overall height ES
package, and the 5 mm × 5 mm × 0.90 mm ET package. The LP
package is a 24-pin TSSOP. All three packages have exposed pads
for enhanced thermal dissipation, and are lead (Pb) free (suffix –T),
with 100% matte tin plated leadframes.
