A.4 - Jan., 2009 APR3011/2/3 www.anpec.com.tw 9 Application Information V CC 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 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 has the duration more than 35 µs, it will generate a reset signal. Connect a 0.1 µF bypass capacitor to the V CC pin can im- prove the transient immunity. Reset Output The APR3011/2/3 have 3 output stage versions: APR3001 is an active low push-pull output. When the V CC drops below the reset threshold, the RESET output generates a low signal. APR3012 is an active high push-pull output. When the V CC drops below the reset threshold, the RE- SET 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 V CC=1.2V; when it is 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 the ground to keep the reset output low (see Figure 1). For the APR3012, a pull-up resistor to V CC is required to keep the valid reset output for VCC below 1.2V. Figure 1. Ensuring RESET Valid to VCC = 0 V Figure 2.
