BD3775AF中文资料2ch 复位+比较器IC数据手册ROHM规格书

描述 Description

BD3775AF是电源电压监视用IC，可在电源电压发生瞬时中断、瞬时降低时产生复位信号，在电源恢复正常时发生上电复位。检测电压除了用于5V电源之外，还有可进行任意电源检测设定的输入，可轻松实现2个系统的电源电压监视。此外，还内置了1个可用于过电压保护及高精度基准电压输出等的比较器，可支持复杂的应用。

特性 Features

• High precision voltage detection(VSA = 4.20V ± 2.5%).
• Internal reset circuit that user selectable thresholdlevel with hysteresis (VSB = 1.230V ± 1.5%). Internal open collector output comparators to create Over Voltage Detection circuit, reference voltage generator, and more. (VSC,OUTC)
• User selectable delay time of releasing reset signal depending on capacitor of CT node.
• Low power dissipation (Icc = 0.35mA ,VCC = 5V).
• SOP8 package (5.0×6.2mm, 1.27mm pitch).
