Features General Description

Applications

•

Computers

• Cell Phones

• Portable Electronics

• µP Power Supply Monitoring

The APR3001/2/3 are designed to monitor voltage
supplies in µP and digital systems. The quiescent
current is extremely low, typically 1.5 µA, making it
ideal for portable battery operated equipment. The
APR3001/2/3 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 APR3001/2/3 series is avail­able with three output stage versions : APR3001
push-pull active low output, APR3002 push-pull ac­tive high output and APR3003 open drain active low
output. They are also designed to reject fast line tran­sient glitches on Vcc. The APR3001/2/3 are come in
a miniature SOT-23, SOT-23-5, SOT-89 packages.

• 1.2V to 6V Input Voltage Range

• Low Quiescent Current : less Than 1.5 µA

• Fixed trimmed reset thresholds for 1.5V, 1.75V,

2.32V, 2.63V, 2.93V, 3.08V, 3.9V, 4.38V.

Application Information

VCC Transient Rejection

The APR3001/2/3 have the function to reject the tran­sient glitches from the power line. The Maximum Tran­sient Duration vs. Reset Threshold Overdrive shows
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.

Reset Output

The APR3001/2/3 have 3 output stage versions:
APR3001 is an active low push-pull output, when the
VCC drops below the reset threshold, the RESET out­put generates a low signal. APR3002 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). APR3003 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 APR3001 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 APR3002, a pull-up resistor to VCC is required
to keep the valid reset output for VCC below 1.2V.
