MIC7211/MIC7221 Rail-to-Rail Input Comparator Features General Description Small Footprint SOT-23-5 Package The MIC7211 and MIC7221 are micropower comparators that feature rail-to-rail input performance Guaranteed Performance at 2.2V, 2.7V, 5V, and in an SOT-23-5 package. The comparators are ideal for 10V systems where small size is a critical consideration. 7 A Typical Supply Current at 5V The MIC7211/MIC7221 are optimized for single supply < 5 s Response Time at 5V operation from 2.2V to 10V power supplies. Push-Pull Output (MIC7211) The MIC7211 features a conventional push-pull output Open-Drain Output (MIC7221) while the MIC7221 has an open-drain output for Input Voltage Range May Exceed Supply Voltage mixed-voltage applications with an external pull-up by 0.3V resistor. >100 mA Typical Sink or Source The MIC7211/MIC7221 benefits small Applications battery-operated portable electronic devices where small size and the ability to place the comparator close Battery-Powered Products to the signal source are primary design concerns.

Electrical specifications do not apply when operating the device outside its recommended operating ratings. Notice: The device is not guaranteed to function outside its operating ratings. Note 1: I/O pin voltage is any external voltage to which an input or output is referenced. 2: Devices are ESD sensitive. Handling precautions recommended. T the 3: The maximum allowable power dissipation is a function of the maximum junction temperature, J(MAX) junction-to-ambient thermal resistance, and the ambient temperature, T . The maximum allowable JA A power dissipation at any ambient temperature is calculated using P = (T T ) . Exceeding the D J(MAX) A JA maximum allowable power dissipation will result in excessive die temperature.
