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. 1 2007/6/21 AGAMEM MICROELECTRONICS INCOPERATION RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.

VRS, reset t voltage, is the detected output point when Vcc is decreasing. TRSD and TRS is the corresponding delay time between the VRSD and VRS to the rising edge and falling edge of Vout. ** After Vout is settled, its rising and falling slope should be equal to the slope of Vcc because there is only a resistance between Vcc and Vout. The maximum value of Vout is equal to the one of Vcc, too. 6 2007/6/21 AGAMEM MICROELECTRONICS INCOPERATION RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
