? 2005-2012 microchip technology inc. ds21985d-page 33 mcp131x/2x 4.3 negative going v dd transients the minimum pulse width (time) required to cause a reset may be an important criteria in the implementation of a power-on reset (por) circuit. this time is referred to as transient duration. the mcp131x/2x devices are designed to reject a level of negative-going transients (glitches) on the power supply line. transient duration is the amount of time needed for these supervisory devices to respond to a drop in v dd . the transient duration time (t tran ) is dependant on the magnitude of v trip C v dd (overdrive). any combination of duration and overdrive that lies under the duration/overdrive curve will not generate a reset signal. generally speaking, the transient duration time decreases with, and increases in, the v trip Cv dd voltage. combinations of duration and overdrive that lie above the duration/overdrive curve are detected as a brown-out or power-down condition. figure 4-16 shows a typical transient duration versus reset comparator overdrive, for which the mcp131x/2x will not generate a reset pulse. it shows that the farther below the trip point the transient pulse goes, the duration of the pulse required to cause a reset gets shorter. figure 4-16 shows the transient response characteristics for the mcp131x/2x. transient immunity can be improved by adding a bypass capacitor (typically 0.1 f) as close as possible to the v dd pin of the mcp131x/2x device. figure 4-16: example of typical transient duration waveform. 4.4 manual reset input the manual reset input pin (mr ) allows the reset pins (rst/rst ) to be manually forced to their active states. the mr pin has circuitry to filter noise pulses that may be present on the pin. figure 4-17 shows a block diagram for using the mcp131x/2x with a push-button switch. to minimize the required external components, the mr input has an internal pull-up resistor. a mechanical push button or active logic signal can drive the mr input. once mr has been low for a time, t mrd (the manual reset delay time), the reset output pins are forced active. the reset output pins will remain in their active states for the reset delay timer time-out period (t r st ). figure 4-18 shows a waveform for the manual reset switch input and the reset pins output. figure 4-17: push button reset and watchdog timer. figure 4-18: mr input ? push button. 4.4.1 noise filter the noise filter filters out noise spikes (glitches) on the manual reset pin (mr ). noise spikes less than 100 ns (typical) are filtered. time (s) 0v supply voltage 5v v trip(min) - v dd t trans v trip(max) v trip(min) (overdrive) (duration) v dd mr v ss rst wdi i/o mclr +5v mcp13xx pic ? mcu rst v il t mr rst t mrd v ih t rst mr the mr input typically ignores input pulses of 100 ns. downloaded from: http:///
mcp131x/2x ds21985d-page 34 ? 2005-2012 microchip technology inc. 4.5 watchdog timer the purpose of the watchdog timer (wdt) is to increase system reliability. the watchdog timer feature can be used to detect when the host controllers program flow is not as expected. the watchdog timer monitors for activity on the watchdog input pin (wdi). the wdi pin is expected to be strobed within a given time frame. when this time frame is exceeded, without an edge transition on the wdi pin, the reset pin is driven active to reset the system. this stops the host controller from continuing its erratic behavior (run-away code execution). the watchdog timer is external to the main portion of the control system and monitors the operation of the system. this feature is enabled by a falling edge on the wdi pin (after device por). monitoring is then done by requiring the embedded controller to force an edge transition (falling or rising) on the wdi pin (pet the watchdog) within a predetermined time frame (t wd ). if the mcp131x/2x does not detect an edge on the wdi pin within the expected time frame, the mcp131x/2x device will force the reset pin active. the watchdog timer is in the disabled state when: the device powers up a por event occurred a wdt event occurred a manual reset (mr ) event occurred when the watchdog timer is in the disabled state, the wdi pin has an internal smart pull-up resistor enabled. this pull-up resistor has a typical value of 52 k ? . this pull-up resistor holds the wdi signal in the high state, until it is forced to another state. after the embedded controller has initialized, if the watchdog timer feature is to be used, then the embed- ded controller can force the wdi pin low (v il ). this also enables the watchdog timer feature and disables the wdi pull-up resistor. disabling the pull-up resistor reduces the devices current consumption. the pull-up resistor will remain disconnected until the device has a power-on, a reset event occurs, or after the wdt time out. once the watchdog timer has been enabled, the host controller must force an edge transition (falling or ris- ing) on the wdi pin before the minimum watchdog timer time out to ensure that the watchdog timer does not force the reset pins (rst/rst ) to the active state. if an edge transition does not occur before the maxi- mum time out occurs, then the mcp131x/2x will force the reset pins to their active state. the mcp131x/2x supports four time outs. the stan- dard offering devices have a typical watchdog timer period (t wdt ) of 1.6 s. ta b l e 4 - 3 shows the available watchdog timer periods. the t wdt time-out is a function of the device voltage and temperature. figure 4-19 shows a block diagram for using the mcp131x/2x with a pic ? microcontroller (mcu) and the watchdog input. table 4-3: watchdog timer periods ( 1 ) figure 4-19: watchdog timer. the software routine that strobes wdi is critical. the code must be in a section of software that is executed frequently enough so the time between edge transitions is less than the watchdog time-out period. one common technique controls the host controllers i/o line from two sections of the program. the software might set the i/o line high while operating in the foreground mode and set it low while in the background or interrupt modes. if both modes do not execute correctly, the watchdog timer issues reset pulses. t wdt units min typ max 4.3 6.3 9.3 ms 71 102 153 ms 1.12 1.6 2.4 sec 17.9 25.6 38.4 sec ?? if the time between wdi edges is less than this, it ensures that the mcp131x/2x never forces a reset if the time between wdi edges is greater than this, it ensures that the mcp131x/2x always forces a reset note 1: shaded rows are custom ordered watch- dog timer periods (t wdt ) time outs. for information on ordering devices with these t wdt time outs, please contact your local microchip sales office. minimum purchase volumes are required. v cc gnd rst wdi mclr +5v mcp13xx 0.1 10 k ? i/o pic ? 3-terminal regulator +5v f mcu (example: mcp1700 ) downloaded from: http:///

(2.5v/1 ma). the value of r 1 + r 2 can be rounded to the nearest standard value and plugged into the equation of figure 5-5 to calculate values for r 1 and r 2 . 1% tolerance resistors are recommended. figure 5-5: modify trip-point using external resistor divider. 5.5 mosfet low-drive protection low operating power and small physical size make the mcp131x/2x series ideal for many voltage detector applications. figure 5-6 shows a low-voltage gate drive protection circuit that prevents overheating of the logic- level mosfet due to insufficient gate voltage. when the input signal is below the threshold of the mcp131x/2x, its output grounds the gate of the mosfet. figure 5-6: mosfet low-drive protection. 5.6 low-power applications in some low-power applications, the longer the micro- controller (such as a pic ? mcu) can be in the sleep mode, the lower the average system current consump- tion will be. the wdt feature can be used to wake-up the pic mcu at a regular interval to service the required tasks before returning to sleep. this wake-up occurs after the pic mcu detects a mclr reset during sleep mode (for mid- range family; por = 1 , bor = 1 , to = 1 , and pd = 1 ). note: in this example, v source must be greater than (v trip ) mcp131x/2x v dd rst v ss r 1 v source r 2 or rst v source r 1 r 1 r 2 + -------------------- ? v trip ? where: v source = voltage to be monitored v trip = threshold voltage setting v dd rst v ss mcp131x/2x 270 ? mtp3055el v dd r l v trip downloaded from: http:///
? 2005-2012 microchip technology inc. ds21985d-page 37 mcp131x/2x 5.7 controllers and processors with bidirectional i/o pins some microcontrollers have bidirectional reset pins. depending on the current drive capability of the controller pin, an indeterminate logic level may result if there is a logic conflict. this can be avoided by adding a 4.7 k ? resistor in series with the output of the mcp131x/2x ( figure 5-7 ). if there are other components in the system that require a reset signal, they should be buffered so as not to load the reset line. if the other components are required to follow the reset i/o of the microcontroller, the buffer should be connected as shown with the solid line. figure 5-7: interfacing the mcp131x/2x push-pull outputs to a bidirectional reset i/o. 5.8 reset signal integrity during power-down the mcp131x/2x reset output is valid to v dd = 1.0v. below this 1.0v, the output becomes an "open circuit" and does not sink or source current. this means cmos logic inputs to the microcontroller will be floating at an undetermined voltage. most digital systems are completely shut down well above this voltage. however, in situations where the reset signal must be maintained valid to v dd = 0v, external circuitry is required. for devices where the reset signal is active-low, a pull- down resistor must be connected from the mcp131x/2x reset pin(s) to ground to discharge stray capacitances and hold the output low ( figure 5-8 ). similarly, for devices where the reset signal is active- high, a pull-up resistor to v dd is required to ensure a valid high reset signal for v dd below 1.0v. this resistor value, though not critical, should be chosen such that it does not appreciably load the reset pin(s) under normal operation (100 k ? will be suitable for most applications). figure 5-8: ensuring a valid active-low reset pin output state as v dd approaches 0v. mcp13xx v dd rst gnd mclr gnd buffered reset to o t h e r s y s t e m components mcu 4.7 k ? buffer pic ? mcp13xx v dd v dd r 1 100 k ? rst gnd downloaded from: http:///
