Application Information
Operation − Power Monitor The ASM1233D −L/1233D/1233M detects out −of− tolerance Power supply conditions. It resets a processor during powerup, Power−down and generates a reset to the system Processor when the monitored power supply voltage is below the reset threshold. When an out−of−tolerance V CC voltage is detected, the RESET signal is asserted. On power−up, RESET is kept active (LOW) for approximately 350 ms after the power supply voltage has reached the selected tolerance. This allows the power supply and microprocessor to stabilize before RESET is released. Figure 3. Timing Diagram: Power−Up Figure 4. Timing Diagram: Power −Down
