MCP120T-270I/TT
The MCP120 is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level. MCP120 features an open drain output, and active low reset and is available in a choice of seven different trip voltages. It operates over the extended industrial temperature range (-40°C/+85°C). MCP120 is available in a TO-92, SOT23-3, and SN packages.
MCP120是一款电压监控设备,旨在保持微控制器处于复位状态,直到系统电压达到适当水平并稳定下来。当电源电压降至安全工作电平以下时,它还可以防止掉电情况。MCP120具有开漏输出和低电平有效复位功能,有七种不同的跳变电压可供选择。它的工作温度范围为-40°C/+85°C扩展工业温度范围。MCP120提供TO-92、SOT23-3和SN三种封装。
