Application Information
VCC
VCC Transient Rejection
The APR3011/2/3 have the function to reject the transient
glitches from the power line. The Maximum Transient
Duration vs. Reset Threshold Overdrive shows at Typical
VCC
Characteristics.The transient voltage with the duration
under the curve will not generate a reset signal, e.g. a
RESET
transient of 100mV below the reset threshold voltage has
the duration more than 35µs, it will generate a reset signal.
Connect a 0.1µF bypass capacitor to the VCC pin can improve the transient immunity.
100K
GND
Reset Output
The APR3011/2/3 have 3 output stage versions: APR3001
Figure 1. Ensuring RESET Valid to VCC = 0 V
is an active low push-pull output. When the VCC drops
below the reset threshold, the RESET output generates
a low signal. APR3012 is an active high push-pull output.
When the VCC drops below the reset threshold, the RE-
+3.3V
+5.0V
output must be connected a pull-up resistor to a supply
voltage that is lower than 6V, it suits to use in multiple
VCC
VCC
voltage systems (see Figure 2). The APR3011 RESET
output is valid until the VCC=1.2V; when it is below 1.2V,
APR3013
SET output generates a high signal (see Timing Chart).
APR3013 is an active low open drain output, the RESET
RESET
the IC is shutdown, and the output becomes a floating
state. If it is a trouble, a resistor should be connected
GND
from reset output to the ground to keep the reset output
low (see Figure 1). For the APR3012, a pull-up resistor to
VCC is required to keep the valid reset output for VCC below
1.2V.
