EM6354中文资料Reset Circuit with Adjustable Delay (1.3V-4.6V, SOT23)数据手册EM Microelectronic规格书

描述 Description

The EM6354 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. When VDD rises above VTH, the output remains active for an additional delay time. This allows the system to stabilize before getting fully active. A reset signal is asserted after a certain delay time. This delay time, or timeout reset period, can be adjusted using an external capacitor. There are 11 standard threshold voltages between 1.31V and 4.63V for use with a wide range of power supplies. The EM6354 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 EM6354 is available in SOT23-5 package. It has an operating temperature range from -40°C to +125°C.
