MIC1555/1557  
IttyBitty® RC Timer / Oscillator  
General Description  
Features  
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.  
• +2.7V to +18V operation  
• Low current  
− <1µA typical shutdown mode (MIC1557)  
− 200µA typical (TRG and THR low) at 3V supply  
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 (TH) has  
precedence over the trigger (TR) input, ensuring that the  
BiCMOS output is off when TR is high.  
• Timing from microseconds to hours  
• “Zero” leakage trigger and threshold inputs  
• 50% square wave with one Resistor, one Capacitor  
• Threshold input precedence over trigger input  
• <15Ω output on resistance  
• No output cross-conduction current spikes  
• <0.005%/°C temperature stability  
• <0.055%/V supply stability  
The MIC1555 may 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.  
• Small SOT-23-5 surface mount package  
Applications  
• Precision timer  
• Pulse generation  
• Sequential timing  
• Time-delay generation  
• Missing pulse detector  
• Micropower oscillator to 5MHz  
• Charge-pump driver  
• LED blinker  
• Voltage converter  
• Linear sweep generator  
• Variable frequency and duty cycle oscillator  
• Isolated feedback for power supplies  
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.  
The MIC1555/7 is available in the SOT-23-5 5-pin  
package, and is rated for –40°C to +85°C ambient  
temperature range
