Document number: DS32131 Rev. 3 - 3 7 of 11 www.diodes.com March 2017 © Diodes Incorporated APX803/D Functional Description Microprocessors (µ Ps) and microcontrollers (µ C) have a reset input to ensure that it starts up in a known state. The APX803/D drive the µP’s reset input to prevent code-execution errors during power-up, power-down, or brownout conditions. They assert a reset signal whenever the VCC supply voltage declines below a preset threshold and keep it asserted for a fixed period of time after V CC has risen above the reset threshold. For the APX803D this p eriod is a minimum of 1ms while for other APX803 variants it is at least 140ms. The APX803/D have an open -drain output stage. Ensuring a Valid Reset Output Down to VCC = 0 RE SE T is guaranteed to be a logic low for VCC > 1V. Once VCC exceeds the reset threshold, an internal timer keeps RE SE T low for the reset timeout period; after this interval, RE SE T goes high. If a brownout condition occurs ( VCC dips below the RE SE T reset threshold), RE SE T goes low. Any time VCC goes below the reset threshold, the internal timer resets to zero, and RE SE T goes low. The internal timer starts after VCC returns above the reset threshold, and RE SE T remains low for the reset timeout period. When VCC falls below 1V, the APX803/D RE SE T output no longer sinks current — it becomes an open circuit. Therefore, high -impedance CMOS logic inputs connected to RE SE T can drift to undetermined voltages. This presents no problem in most applications since most µ P and other circuitry is inoperative with VCC below 1V. Interfacing to µ P with Bidirectional Reset Pins Since the RESET output on the APX803/D is open drain, this device interfaces easily with μP/µC that have bidirectional reset pins, such as the Motorola 68HC11. Connecting the μP supervisor’s RESET output directly to the microcontroller’s (μC’s) RESET pin with a single pull -up resistor allows either device to assert reset. Supervising and Monitoring Multiple Supplies Generally, the pull-up resistor connected to the APX803/D will connect to the supply voltage that is being monitored at the IC’s VCC pin. However, some systems may use the APX803/D open -drain output to level-shift from the monitored supply to reset the µ P powered by a different supply voltage or monitor multiple supplies that will be fed into 1 µ C/µ P reset input.
