BCD Semiconductor Manufacturing Limited
General Description
The AZ70XX series ICs are under voltage detectors
with a built in voltage threshold and low power con-
sumption. The AZ70XX are specifically designed to
accurately monitor power supplies.
The AZ70XX use a precision on-chip voltage refer-
ence and a comparator to measure the input operating
voltage. These ICs can accurately reset the system after
detecting voltage at the time of switching power on and
instantaneous power off in various CPU systems and
other logic systems. The detect voltage thresholds are
2.3V/2.5V/2.7V/2.9V/3.1V/3.3V/4.2V/4.5Vfor
AZ7023/25/27/29/31/33/42/45 respectively. Built in
hysteresis helps to prevent erratic operation in the pres-
ence of noise.
The AZ70XX series are available in 2 standard pack-
ages: TO-92 and SOT-89-3.

Figure 12 is a typical timing waveform for AZ70XX
during power-up and temporary power-down period.
Here is some explanations for AZ70XX's operation.
1. During power-up period, V
OUT
will remain
undefined until V
CC
rises above V
OPR
(typically
0.8V). After that moment, the output will become
valid and will be at its logic low state while
V
OPR
<V
CC
<V
S
for power-up operating.
2. After a delay time of tpLH from the moment
V
CC
>V
S
, the V
OUT
will be at its logic high state. In
general, V
OUT
is dependent upon the voltage that the
pull up resistor connected to.
3. During power-down, after a delay time of tpHL
from the moment V
CC
<V
S
-V
HYS
, V
OUT
will be at its
logic low state. In general, at rated output current and
V
CC,
V
OUT
can be pulled down to a voltage as low as
within 0.4V from GND. (See the Electrical
Characteristics section).
4. V
OUT
will be at its logic low state while V
S
-
V
HYS
>V
CC
>V
OPR
for power-down operating.
5. After V
CC
falls below V
OPR
, the output is
undefined.
