S1A0051 fet driver for class-d pwm amp digital & analog co., ltd. (rev. 1.1) -6- 6. fuctional description please refer to notes on s1a0071 for more details on the class- d amp. S1A0051 can be used not only in one power supply mode(+10v ~ +1 2v) but also in dual power supply mode( 5v ~ 6v ). it can receive input signals th rough the schmitt trigger, and has a built-in logic power supply, which makes the logic le vel independent of the input level when the input signal level is different from the output signal level. S1A0051 drives inputs and outputs that have a non-inverse relation S1A0051 dri ves each output that have a non-inverse relation about each input and it has superior short propagation delay and fast rising/falling timing characteristics. input interface (schmitt trigger) in S1A0051, the built-in logic power supply sets the internal l ogic operating voltage, and the power supply voltage range is 5.0v 0.5v for dual power supply mode. by interfacing with the schmitt trigger with a hyste resis, the input is unaffected by noise. driver & 1/2 bias configured as cmos, excluding tot em pole output stage, to enhan ce switching characteristics, the driver generates the center operating voltage (1/2 bias) to prevent mos breakdown when the process cmos breakdown voltage bvgs is 8v. S1A0051's i nput/output relationship is non-inverted, which is shown in the timing diagram in figure . 1. input output td tf 10% tr 90% 90% 10% figure 1. input vs. output timing diagram
