DESCRIPTION
The SA08 is a pulse width modulation amplifier that can
supply 9KW to the load. An internal oscillator requires no
external components. The clock input stage divides the oscil-
lator frequency by two, which provides the switching frequency
of 22.5 kHz. The oscillator may also be used to synchronize
multiple amplifiers. Current sensing is provided for each half
of the bridge giving amplitude and direction data. A shutdown
input turns off all four drivers of the H-bridge output. A high
side current limit and the programmable low side current limit
protect the amplifier from shorts to supply or ground in addition
to load shorts. The H-bridge output IGBTs are protected from
thermal overloads by directly sensing the temperature of the
die. The 12-pin hermetic MO-127 power package occupies
only 3 square inches of board space.
