Chipown AP0809 3-Pin Microprocessor Reset Circuits Description Features The AP0809 microprocessor supervisory circuit can be used to monitor the power supplies in microprocessor and digital systems. It provides a reset to the microprocessor during power-up, power-down, and brown-out conditions. The function of the AP0809 is to monitor the VCC supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold. The reset signal remains asserted for 250ms after VCC rises above the threshold. The AP0809 has an active-low RESET output. With a low supply current of only 2μA (Typ.), the AP0809 are ideal for use in portable equipment. The AP0809 is available in the 3-pin SOT23 package.  Precise monitoring of 2.7V, 3.0V, 3.3V and 5.0V supplies  140 ms min. Power-On Reset pulse width, 250ms typical, has an active-low RESET Output  Guaranteed RESET Output valid for VCC≥1.1 V  Low Supply Current, 2μA Typ.  Available in small SOT23 package  No external components needed  Specified over full temperature range -40°Cto+105°C Package Applications       Microprocessor Systems Computers Controllers Intelligent Instruments Portable/Battery-Powered Equipment Automotive Typical Application Figure 2 Typical Application Function Diagram Figure 3 8/F, ChuangYuan Building Function Digram No.21-1 Changjiang Road, Wuxi New Destrict Tel: +86(510)8521-7718 Ver 1.3 http://www.chipown.com.cn 1

Chipown AP0809 三管脚的微处理器复位芯片概述 AP0809 是一种单一功能的微处理器复位芯片，用于监控微控制器和其他逻辑系统的电源电压。它可以在上电、掉电和节电情况下向微控制器提供复位信号。当电源电压低于预设的门槛电压时，芯片会发出复位信号，在电源电压恢复到高于门槛电压一段时间(250ms 典型值)后，这个复位信号才会结束。 AP0809 有效的复位输出为低电平。 2μA 的典型低电源电流，使 AP0809 能理想地用于便携式、电池供电的设备。AP0809 采用 3 管脚的 SOT23 封装。      VCC≥1.1V 保证复位输出有效低电源电流，2μA 典型值采用小型的 SOT23 封装无需外部元件规定整个温度范围为-40℃~+105℃ 封装 SOT23-3L 应用       微处理器系统计算机控制器智能仪器便携式/电池供电设备汽车 SOT23 特性  精确监控 2.7V，3.0V，3.3V、5.0V 电源  电源复位延时时间最小为 140ms，典型值为 250ms，具有低有效的复位输出典型应用电路图图 1 典型应用电路中国·无锡新区长江路 21-1 号创源大厦 8 楼电话：+86(510)85217718 网址：http://www.chipown.com.cn V2.4 1/5
