/** TI BQ51013B Qi (WPC v1.2 BPP) wireless-power receiver, VQFN-20 RHL 3.5 x 4.5 mm.
 * Pin numbers from the datasheet SLUSB62D pin table; land pattern from TI drawing
 * RHL0020A (docs/sources.md [bq51013b]): 20 lands 0.24 x 0.6 mm on a 0.5 mm pitch,
 * centre spans 3.3 mm (X) and 4.3 mm (Y), exposed pad 2.05 x 3.05 mm. The lands here
 * are 0.28 x 0.70 mm (JLC/EasyEDA C55663 uses 0.28 x 0.85) so the toe is inspectable.
 * Orientation: TI top view, long (4.5 mm) sides vertical. Pin 1 top-left on the short
 * side, numbering counter-clockwise: 1, 20 on top; 2-9 down the left; 10, 11 on the
 * bottom; 12-19 up the right. */
