General Description
AA16 Series is a three terminal power reset generator processed in a standard CMOS. It detects a particle fixed voltage at the power up or down procedure to generate a reset signal for initializing the following systems or devices, such as MCU. There is a typical 150/200mv hysteresis range for different 3.3V/5V system to prevent the system from crashing during power supply fluctuation. AA16 Series consists of a reference voltage generator, a comparator with hysteresis function and an ¡¥open-drain¡¦ type (AA16N series) or ¡¥Inverter¡¦ type (AA16C series) output driver. The volt level of output is flexible to the various application power systems. Low power consumption, typical at 1uA and maximum is lower than 2uA.
