Description
The IC drives directly small DC inductive or active
loads like electric motors, lamps, etc. There are four
main driving modes. These are set by digital inputs
“In1” and “In2” :
The current of the output-drivers is limited for all
kinds of overload- and short-circuit conditions and in
the whole supply voltage- and temperature range.
The outputs “M1” and “M2” need to be off-chip
protected with against motor inductances by
standard Si-diodes.
If the temperature of the chip exceeds a certain
value (changable with pin “Auto”), the temperature-
overload protection-circuit disables the outputs,
preventing the chip from being overheated. In
addition, this so called “temp ovl”-state is signaled
with a low level at the “overtemp”-pin.
