DESCRIPTION
The SA13 is a half bridge pulse width modulation amplifier that can supply 3000W to the load. Flexible frequency control is provided. An internal 45kHz oscillator requires no external components and can be used to synchronize multiple amplifiers. The oscillator output may be divided down and connected to the clock input to lower the switching frequency . The clock input stage divides by two and determines the output switching rate (normally 22.5 kHz). A shutdown input turns off both output drivers. High side current sensing protects the amplifier from shorts to ground. In addition, the half bridge output MOSFETs 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.
NC * VCC * +VS OUT PWR GND
Case tied to pin 5. Allow no current in case. Bypassing of supplies is required. Package is Apex MO-127 (STD). See Outline Dimensions/Packages in Apex data book. If +PWM < RAMP/PWM then OUT = HIGH. *See text.

Each of the two output transistors can dissipate 150W. Unless otherwise noted: TC = 25°C, VS, VCC at typical specification. 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. Guaranteed but not tested. If 100% duty cycle is not required VS(MIN) = 0V. The SA13 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.
