EM6352数据手册集成电路（IC）的监控器规格书PDF

描述 Description

The EM6352 monitors the supply voltage of any electronic system, and generates the appropriate reset signal. The threshold defines the minimum allowed voltage which guarantees the good functionality of the system. As long as VDD stays above the threshold voltage, the output stays inactive. If VDD drops below VTH, the output gets active. The EM6352 asserts a reset signal without a delay time and is thus a simple voltage detector. There are 11 standard threshold voltages between 1.31V and 4.63V for use with a wide range of power supplies. The EM6352 features three output types: active-low push-pull, active-low open-drain and active-high push-pull. The output is guaranteed to be in the correct state for VDD down to 0.8V. The EM6352 is available in SOT23-3L and SOT23-5L packages, and has an operating temperature range from -40°C to +125°C.
