N82C542B Datasheet The PWM225 is a pulse width amplifier than can supply 5000W to the load.. An intemal oscillator provides a lOOKhz switching frequency requiring no extemal components. External oscillators may also be used t0 10wer the switching firequency or to synchronize multiple amplifiers. Current sensing is provided for each half of the bridge giving amplitude and direction data A shutdown input tums off all four drivers of the H bridge output. A high side current limit and the programmable low side cut limit protect the amplifier from shorts to supply or grormd 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 M0-127 power package occupies only 3 square inches of board space. Pin diameter is .060". BLOCK DIAGRAM N82C542B Price

The drivers are mverting transmitters, which accept either TTL or CMOS inputs and output the RS-232 signals with an inverted sense relative to the input logic levels. Typically, the RS-232 output voltage swingis +9V with no load, and +5V minimum with full load. The transmitter outputs are protected against infinite short-circuits to ground without degradation in reliability. The drivers of the SP211EH, and SP213EH can be tri-stated by using the SHUTDO~rN function. |
