The MCP121 Series of CMOS voltage detectors are well suited for many portable and consumer electrics applications due to the extremely low 1uA operating current and small surface-mount packaging. These devices are designed to hold the microcontroller in reset until the supply voltage reaches a predetermined operating level. These devices also protect against brownout conditions that occur as a result of the supply voltage dropping below a tolerable level.

   Operating current: 1.75uA (max)

   Wide Voltage range: 1.0V to 5.5V

   Available Trip Points: 1.9V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, 4.63V

   Trip point accuracy: +/- 1.5%

   Output Options: Open-Drain

   Package options: SOT23-3, SC70-3, TO92-3
