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.

* VRSD, reset disable voltage, is the detected output point when Vcc is increasing. 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.

** In the Vcc increasing procedure, Vout equal to Vcc as Vcc is larger than VRSD. In the
Vcc decreasing procedure, Vout won’t be change to Vcc until Vcc is smaller than VRS. The
width between VRS and VRSD is so called ‘Hysteresis range’
