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.
●Features
●• +2.7V to +18V operation
●•Low current
●− <1µA typical shutdown mode (MIC1557)
●− 200µA typical (TRG and THR low) at 3V supply
●• 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
●• Small SOT-23-5 surface mount package
