driver independently. When the device is set up in an
H−Bridge configuration, the software design has to take care
of avoiding simultaneous activation of connected HS and LS
transistors. Resulting high shoot through currents could
cause irreversible damage to the device.

Overvoltage Clamping − Driving Inductive Loads
in a single−side−mode (LS or HS switch, no freewheeling
path), external clamping diodes for inductive turn off of the
low side driver must be provided. The maximum clamp
voltage is 48 V. Due to high power dissipation during
clamping, the maximum energy capability of the driver
transistor has to be considered.
