The Maximum Transient 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. 100K GND Figure 1. Ensuring RESET Valid to VCC = 0 V Reset Output +3.3V 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 output 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. Copyright ANPEC Electronics Corp. Rev.
