1. The ILIM data is for 1 channel of BTL configuration, thus, 2 * ILIM drives the 2-channel BTL configuration.

The current limit is active when OCRB = 0 (see Table 23: Overcurrent warning detect adjustment bypass

on page 29. When OCRB = 1 then ISC applies.

2. The ISCP current limit data is for 1 channel of BTL configuration, thus, 2 * ISCP drives the 2-channel BTL

configuration. The short-circuit current is applicable when OCRB = 1 (see Table 23: Overcurrent warning

detect adjustment bypass on page 29.
