voltage exceeding the low-side clamping voltage (V
DRN_CL1-6
) , while the high one of
the high-side drivers is turned on, may cause a destruction of the device.
Caution: In bridge mode using channels 2 and 5, the IN/PWM pin has to be grounded. Therefore
PWM mode on other channels is not possible.

2.6 LED mode
Open-load detection in off-state can be deactivated to avoid the turn on of the LEDs by the
current source (150 µA typ.) when the channel is switched-off.
Moreover, it is possible to select a high slew rate to support PWM operations with small duty
cycle (see Section 9.3.1: Channel configuration decoding).
