General Description
The MIC1555 IttyBitty
CMOS RC timer/oscillator and
MIC1557 IttyBitty
CMOS RC oscillator are designed to
provide rail-to-rail pulses for precise time delay or
frequency generation.
The devices are similar in function to the industry standard
“555”, without a frequency control (FC) pin or an open-
collector discharge (D) pin. The threshold pin (THR) has
precedence over the trigger (TRG) input, ensuring that the
BiCMOS output is off when TRG is high.
The MIC1555 can be used as an astable (oscillator) or
monostable (one-shot) with separate threshold and trigger
inputs. In the one-shot mode, the output pulse width is
precisely controlled by an external resistor and a capacitor.
Time delays may be accurately controlled from micro-
seconds to hours. In the oscillator mode, the output is
used to provide precise feedback, with a minimum of one
resistor and one capacitor producing a 50% duty cycle
square wave.
The MIC1557 is designed for astable (oscillator) operation
only, with a chip select/reset (CS) input for low power shut-
down. One resistor and one capacitor provide a 50% duty
cycle square wave. Other duty-cycle ratios may be
produced using two diodes and two resistors.
The MIC1555/7 is powered from a +2.7V to +18V supply
voltage and is rated for –40°C to +85°C ambient
temperature range. The MIC1555/7 is available in SOT-23-
5, and thin SOT23-5 5-pin packages. A low profile, ultra-
thin, (UTDFN), version of the MIC1555 (with chip select) is
also available.
Datasheets and support documentation are available on
Micrel’s web site at: www.micrel.com.
