APR3003 Open Drain Output with Multiple Supplies 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; 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 APR3002, a pull-up resistor to the VCC is required to keep the valid reset output for VCC below 1.2V. V CC V CC RESET GND 100K Figure 1.
