Technical Data
Technical Data
A permanent external pin voltage above the minimum Zener break-down
voltage can destroy the driver.
The low side drivers have a short circuit protection feature. Whenever
the drain current of the LDMOS transistor exceeds a fixed value, the
output is automatically switched off (i.e. the LDMOS is in the high
impedance state) and the corresponding short circuit flag is set (SCIF5
or SCIF6). If the SCIE5/6 bits are enabled, an interrupt occurs. As long
as the SCIF5/6 bits are set, the output cannot be switched on. These bits
are cleared by writing a logical 1 to the corresponding bit location. The
outputs are also protected by a common over temperature detection.
