9 sp705ds/09 sp705 low power microprocessor supervisory circuits ? copyright 2000 sipex corporation features the sp705-708/813l/813m series provides four key functions: 1. a reset output during power-up, power-down and brownout conditions. 2. an independent watchdog output that goes low if the watchdog input has not been toggled within 1.6 seconds. 3. a 1.25v threshold detector for power-fail warning, low battery detection, or monitoring a power supply other than +5v. 4. an active-low manual-reset that allows reset to be triggered by a pushbutton switch. the sp707/708 devices are the same as the sp705/706 devices except for the active-high reset substitution of the watchdog timer. the sp813l is the same as the sp705 except an active-high reset is provided rather than an active-low reset. the sp705/707/813l devices generate a reset when the supply voltage drops below 4.65v. the sp706/708/813m devices generate a reset below 4.40v. the sp705-708/813l/813m series is ideally suited for applications in automotive systems, intelligent instruments, and battery-powered computers and controllers. the sp705-708/813l/ 813m series is ideally applied in environments where monitoring of power supply to a m p and its related components is critical. theory of operation the sp705-708/813l/813m series is a microprocessor ( m p) supervisory circuit that monitors the power supplied to digital circuits such as microprocessors, microcontrollers, or memory. the series is an ideal solution for portable, battery-powered equipment that requires power supply monitoring. implementing this series will reduce the number of components and overall complexity. the watchdog functions of this product family will continuously oversee the operational status of a system. the operational features and benefits of the sp705-708/813l/ 813m series are described in more detail below. reset output a microprocessor's reset input starts the m p in a known state. the sp705-708/813l/813m series asserts reset during power-up and prevents code execution errors during power- down or brownout conditions. on power-up, once v cc reaches 1v, reset is a guaranteed logic low of 0.4v or less. as v cc rises, reset stays low. when v cc rises above the reset threshold, an internal timer re- leases reset after 200ms. reset pulses low whenever v cc dips below the reset thresh- old, such as in a brownout condition. when a brownout condition occurs in the middle of a previously initiated reset pulse, the pulse con- tinues for at least another 140ms. on power- down, once v cc falls below the reset threshold, reset stays low and is guaranteed to be 0.4v or less until v cc drops below 1v. the sp707/708/813l/813m active-high reset output is simply the complement of the reset output and is guaranteed to be valid with v cc down to 1.1v. some m ps, such as intel's 80c51, require an active-high reset pulse. watchdog timer the sp705/706/813l/813m watchdog circuit monitors the m p's activity. if the m p does not toggle the watchdog input (wdi) within 1.6 seconds and wdi is not tri-stated, wdo goes low. as long as reset is asserted or the wdi input is tri-stated, the watchdog timer will stay cleared and will not count. as soon as reset is released and wdi is driven high or low, the timer will start counting. pulses as short as 50ns can be detected.
sp705ds/09 sp705 low power microprocessor supervisory circuits ? copyright 2000 sipex corporation 10 typically, wdo will be connected to the non-maskable interrupt input (nmi) of a m p. when v cc drops below the reset threshold, wdo will go low whether or not the watch- dog timer has timed out. normally this would trigger an nmi but reset goes low simulta- neously, and thus overrides the nmi. if wdi is left unconnected, wdo can be used as a low-line output. since floating wdi disables the internal timer, wdo goes low only when v cc falls below the reset threshold, thus func- tioning as a low-line output. figure 14. sp705/706/813l/813m watchdog timing waveforms figure 15. sp705/706 timing diagrams with wdi tri-stated. the sp707/708/813l/813m reset output is the inverse of the reset waveform shown. t rs reset* wdo 0v +5v wdi reset* 0v +5v 0v +5v 0v +5v t wd t wd t wd t wp * externally triggered low by mr, reset is for the sp813l/813m only v cc reset 0v +5v 0v +5v 0v +5v t rs t rs t mr 0v +5v mr* wdo v rt v rt *externally driven low t md
11 sp705ds/09 sp705 low power microprocessor supervisory circuits ? copyright 2000 sipex corporation power-fail comparator the power-fail comparator can be used for various purposes because its output and noninverting input are not internally connected. the inverting input is internally connected to a 1.25v reference. to build an early-warning circuit for power failure, connect the pfi pin to a voltage divider as shown in figure 16 . choose the voltage divider ratio so that the voltage at pfi falls below 1.25v just before the +5v regulator drops out. use pfo to interrupt the m p so it can prepare for an orderly power-down. manual reset the manual-reset input (mr) allows reset to be triggered by a pushbutton switch. the switch is effectively debounced by the 140ms mini- mum reset pulse width. mr is ttl/cmos logic compatible, so it can be driven by an external logic line. mr can be used to force a watchdog timeout to generate a reset pulse in the sp705/706/813l/813m . simply connect wdo to mr. ensuring a valid reset output down to v cc = 0v when v cc falls below 1v, the sp705/706/707/ 708 reset output no longer sinks current, it becomes an open circuit. high-impedance cmos logic inputs can drift to undetermined voltages if left undriven. if a pull-down resistor is added to the reset pin, any stray charge or leakage currents will be shunted to ground, holding reset low. the resistor value is not critical. it should be about 100k w , large enough not to load reset and small enough to pull reset to ground. monitoring voltages other than the unregulated dc input monitor voltages other than the unregulated dc by connecting a voltage divider to pfi and adjusting the ratio appropriately. if required, add hysteresis by connecting a resistor (with a value approximately 10 times the sum of the two resistors in the potential divider network) between pfi and pfo. a capacitor between pfi and gnd will reduce the power-fail circuit's pfi pfo v cc +5v gnd reset to m p mr +12v 1m w 1% 130k w 1% figure 17. monitoring both +5v and +12v power supplies gnd gnd reset interrupt i/o line v cc reset pfo pfi r 2 r 1 unregulated dc power supply regulated +5v power supply v cc 0.1 m f pfi m p nmi wdo pushbutton switch mr sp705 sp706 sp813l sp813m figure 16. typical operating circuit
