adm6316/adm6317/adm6318/adm 6319/adm6320/adm6321/adm6322 rev. d | page 9 of 16 circuit description the adm6316/adm6317/adm6318/adm6319/adm6320/ adm6321/adm6322 provide microprocessor supply voltage supervision by controlling the microprocessors reset input. code execution errors are avoided during power-up, power-down, and brownout conditions by asserting a reset signal when the supply voltage is below a preset threshold and by allowing supply voltage stabilization with a fixed timeout reset pulse after the supply voltage rises above the threshold. in addition, problems with microprocessor code execution can be monitored and corrected with a watchdog timer (adm6316/adm6317/ adm6318/adm6320/adm6321). if the user detects a problem with the systems operation, a manual reset input is available (adm6316/adm6317/adm6319/adm6320/adm6322) to reset the microprocessor, for example, by means of an external push button. reset output the adm6316 features an active-low push-pull reset output, while the adm6317/adm6321/adm6322 have active-high push-pull reset outputs. the adm6318/adm6319 feature dual active-low and active-high push-pull reset outputs. for active- low and active-high outputs, the reset signal is guaranteed to be logic low and logic high, respectively, for v cc down to 1 v. the reset output is asserted when v cc is below the reset thresh- old (v th ), when mr is driven low, or when wdi is not serviced within the watchdog timeout period (t wd ). reset remains asserted for the duration of the reset active timeout period (t rp ) after v cc rises above the reset threshold, after mr transitions from low to high, or after the watchdog timer times out. illustrates the behavior of the reset outputs. figure 17 v cc 1v v cc 0v v cc 0v v th v th 0v v cc reset reset t rd t rd 1v t rp t rp 04533-019 figure 17. reset timing diagram open-drain reset output the adm6320/adm6321/adm6322 have an active-low, open- drain reset output. this output structure requires an external pull-up resistor to connect the reset output to a voltage rail no higher than 6 v. the resistor should comply with the micro- processors logic low and logic high voltage level requirements while supplying input current and leakage paths on the reset line. a 10 k resistor is adequate in most situations. manual reset input the adm6316/adm6317/adm6319/adm6320/adm6322 feature a manual reset input ( mr ), which when driven low, asserts the reset output. when mr transitions from low to high, reset remains asserted for the duration of the reset active timeout period before deasserting. the mr input has a 52 k, internal pull-up so that the input is always high when unconnected. an external push-button switch can be connected between mr and ground so that the user can generate a reset. debounce circuitry for this purpose is integrated on chip. noise immunity is provided on the mr input, and fast, negative-going transients of up to 100 ns (typical) are ignored. a 0.1 f capacitor between mr and ground provides additional noise immunity. watchdog input the adm6316/adm6317/adm6318/adm6320/adm6321 feature a watchdog timer that monitors microprocessor activity. a timer circuit is cleared with every low-to-high or high-to-low logic transition on the watchdog input pin (wdi), which detects pulses as short as 50 ns. if the timer counts through the preset watchdog timeout period (t wd ), reset is asserted. the micro- processor is required to toggle the wdi pin to avoid being reset. failure of the microprocessor to toggle wdi within the timeout period, therefore, indicates a code execution error, and the reset pulse generated restarts the microprocessor in a known state. as well as logic transitions on wdi, the watchdog timer is also cleared by a reset assertion due to an undervoltage condition on v cc or due to mr being pulled low. when reset is asserted, the watchdog timer is cleared and does not begin counting again until reset deassserts. the watchdog timer can be disabled by leaving wdi floating or by three-stating the wdi driver. v cc 1v v cc 0v v cc 0v v th 0v v cc wdi reset t rp t rp t wd 04533-022 figure 18. watchdog timing diagram
adm6316/adm6317/adm6318/adm 6319/adm6320/adm6321/adm6322 rev. d | page 10 of 16 applications information watchdog input current to minimize watchdog input current (and minimize overall power consumption), leave wdi low for the majority of the watchdog timeout period. when driven high, wdi can draw as much as 160 a. pulsing wdi low-to-high-to-low at a low duty cycle reduces the effect of the large input current. when wdi is unconnected, a window comparator disconnects the watchdog timer from the reset output circuitry so that reset is not asserted when the watchdog timer times out. negative-going v cc transients to avoid unnecessary resets caused by fast power supply transients, the adm6316/adm6317/adm6318/adm6319/adm6320/ adm6321/adm6322 are equipped with glitch rejection circuitry. the typical performance characteristic in figure 14 plots v cc transient duration vs. the transient magnitude. the curves show combinations of transient magnitude and duration for which a reset is not generated for 4.63 v and 2.93 v reset threshold parts. for example, with the 2.93 v threshold, a transient that goes 100 mv below the threshold and lasts 8 s typically does not cause a reset, but if the transient is any larger in magnitude or duration, a reset is generated. an optional 0.1 f bypass capacitor mounted close to v cc provides additional glitch rejection. ensuring reset valid to v cc = 0 v both active-low and active-high reset outputs are guaranteed to be valid for v cc as low as 1 v. however, by using an external resistor with push-pull configured reset outputs, valid outputs for v cc as low as 0 v are possible. for an active-low reset output, a resistor connected between reset and ground pulls the output low when it is unable to sink current. for the active-high case, a resistor connected between reset and v cc pulls the output high when it is unable to source current. a large resistance, such as 100 k, should be used so that it does not overload the reset output when v cc is above 1 v. adm6316/ adm6318/ adm6319 v cc reset 100k ? adm6317/ adm6318/ adm6319/ adm6321/ adm6322 v cc reset 100k ? 0 4533-018 figure 19. ensuring reset valid to v cc = 0 v watchdog software considerations in implementing the microprocessors watchdog strobe code, quickly switching wdi low to high and then high to low (mini- mizing wdi high time) is desirable for current consumption reasons. however, a more effective way of using the watchdog function can be considered. a low-to-high-to-low wdi pulse within a given subroutine prevents the watchdog from timing out. however, if the sub- routine becomes stuck in an infinite loop, the watchdog cannot detect this because the subroutine continues to toggle wdi. a more effective coding scheme for detecting this error involves using a slightly longer watchdog timeout. in the program that calls the subroutine, wdi is set high. the subroutine sets wdi low when it is called. if the program executes without error, wdi is toggled high and low with every loop of the program. if the subroutine enters an infinite loop, wdi is kept low, the watchdog times out, and the microprocessor is reset (see figure 20 ). start set wdi high program code subroutine set wdi low return infinite loop: watchdog times out reset 04533-021 figure 20. watchdog flow diagram reset reset wdi i/o mr adm6316 v cc microprocessor 04533-020 figure 21. typical application circuit
