DESCRIPTION

The SA06 is a pulse width modulation amplifier that can
supply 5000W to the load. An internal oscillator requires no
external components. The clock input stage divides the oscil­lator frequency by two, which provides the switching fre­quency of 22.5 kHz. External oscillators may also be used to
lower the switching frequency or 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 MOSFETs are protected
from thermal overloads by directly sensing the temperature of
the die. The 12-pin hermetic MO-127/40S power package
occupies only 3 square inches of board space.

NOTES: 1. Each of the two active output transistors can dissipate 150W.

2. Unless otherwise noted: TC = 25°C, VS, VCC at typical specification.

3. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power
dissipation to achieve high MTTF. For guidance, refer to the heatsink data sheet.

4. Guaranteed but not tested.

5. If 100% duty cycle is not required V

CAUTION

The SA06 is constructed from MOSFET transistors. ESD handling procedures must be observed.

The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush,
machine, or subject to temperatures in excess of 850°C to avoid generating toxic fumes.
