Microchip | MIC7221YM5-TR

MIC7221YM5 TR is a micropower comparator featuring rail-to-rail input performance in Micrel’s IttyBitty™ SOT-23-5 package.

The MIC7211/21 is ideal for systems where small size is a critical consideration. The MIC7211/21 is optimized for single supply operation from 2.2 V to 10 V power supplies. The MIC7211 features a conventional push-pull output while the MIC7221 has an open-drain output for mixed-voltage applications with an external pull-up resistor. The MIC7211/21 benefits small battery-operated portable electronic devices where small size and the ability to place the comparator close to the signal source are primary design concerns.

Key Features:

• Small footprint SOT-23-5 package.
• Guaranteed performance at 2.2 V, 2.7 V, 5 V, and 10 V.
• 7 µA typical supply current at 5 V.
• <5 µs response time at 5 V.
• Push-pull output (MIC7211).
• Open-drain output (MIC7221).
• Input voltage range may exceed supply voltage by 0.3 V.
• >100 mA typical sink or source.

Applications:

• Battery-powered products.
• Notebook computers and PDAs.
• PCMCIA cards.
• Cellular and other wireless communication devices.
• Alarm and security circuits.
• Direct sensor interface.
