MCP121 _ BDTIC a Leading Distributor in China

MCP121

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.

Features

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
