•
1.2V to 5.5V Input Voltage Range
The APR3021/2/3 are designed to monitor voltage
supplies in µP and digital systems. The quiescent
current is extremely low, typically 1.5 µA, making it
Low Quiescent Current : less Than 1.5 µA
High accuracy detection threshold : ±1.5%
Fixed trimmed reset thresholds for 1.5V, 1.75V, ideal for portable battery operated equipment. The
2.32V, 2.63V, 2.93V, 3.08V, 3.9V, 4.38V.
Reset Timeout Period 250ms
APR3021/2/3 operate by monitoring the system
power supply voltage. When the input voltage drops
below a fixed threshold, the device asserts a reset
signal for a fixed time period after Vcc rises above
the fixed threshold. The APR3021/2/3 series is avail-
able with three output stage versions : APR3021
push-pull active low output, APR3022 push-pull ac-
tive high output and APR3023 open drain active low
output. They are also designed to reject fast line tran-
sient glitches on Vcc. The APR3021/2/3 are come in
a miniature SOT-23, SOT-23-5, SOT-89 packages.

Application Information
VCC
VCC Transient Rejection
The APR3021/2/3 have the function to reject the tran-
sient glitches from the power line. The Maximum Tran-
sient Duration vs. Reset Threshold Overdrive shows
VCC
RESET
at Typical Characteristics.The transient voltage with
the duration under the curve will not generate a reset
signal, e.g. a transient of 100mV below the reset
threshold voltage have the duration more than 35us, it
will generate a reset signal. Connect a 0.1uF bypass
capacitor to the VCC pin can improve the transient
immunity.

Figure 1. Ensuring RESET Valid to VCC = 0 V
Reset Output
+3.3V
+5.0V
The APR3021/2/3 have 3 output stage versions:
APR3001 is an active low push-pull output, when the
VCC drops below the reset threshold, the RESET out-
put generates a low signal. APR3022 is an active high
push-pull output, when the VCC drops below the reset
threshold, the RESET output generates a high signal
(see Timing Chart). APR3023 is an active low open
drain output, the RESET output must be connected a
pull-up resistor to a supply voltage that is lower than
6V, it suits to use in multiple voltage systems (see
Figure 2). The APR3021 RESET output is valid until
the VCC=1.2V, below 1.2V the IC is shutdown, and
the output becomes a floating state. If it is a trouble, a
resistor should be connected from reset output to
ground to keep the reset output low (see Figure 1).
For The APR3022, a pull-up resistor to VCC is required
to keep the valid reset output for VCC below 1.2V.
