Figure 2. Oscillator Diagram
The MIC1555 or MIC1557 can be used to construct an
oscillator.
The frequency of an astable oscillator is:
RC
k
1
f
1
=
where:
f = frequency (Hz)
k1 = Constant (see Typical Characteristics)
R = Resistance ()
C = Capacitance (F)
To use the MIC1555 as an oscillator, connect TRG to
THR.
Figure 3. MIC1555 Oscillator Configuration
The MIC1555YMU and MIC1557 feature a CS input. With
a logic-low signal, CS places the part into a <1A
shutdown state. If unused, the CS input must be pulled
up.
Figure 4. MIC1557 Oscillator Configuration
Falling-Edge Triggered Monostable Circuit
The MIC1555 may be triggered by an AC-coupled falling-
edge, as shown in Figure 5. The RC time constant of the
input capacitor and pull-up resistor should be less than
the output pulse time, to prevent multiple output pulses. A
diode across the timing resistor provides a fast reset at
the end of the positive timing pulse.
