Application Information
VCC Transient Rejection
V CC
The APR3011/2/3 have the function to reject the transient glitches from the power line. The Maximum Tran-
V CC
sient Duration vs. Reset Threshold Overdrive shows
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
The APR3011/2/3 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. APR3012 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). APR3013 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 APR3011 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 APR3012, a pull-up resistor to VCC is required
to keep the valid reset output for VCC below 1.2V.
