R5106N SERIES
Microprocessor Supervisory Circuit with Inhibit pin
NO.EA-169-151222

OUTLINE
The R5106N is a microprocessor supervisory circuit and has high accuracy and ultra low supply current voltage
detector with built-in delay circuit and watchdog timer. When the supply voltage is down across the threshold,
or the watchdog timer does not detect the system clock from the microprocessor, the reset output is generated.
The voltage detector circuit is used for the system reset, etc. The detector threshold is fixed internally, and the
accuracy is ±1.0%. The released delay time (Power-on Reset Delay) circuit is built-in, and output delay time is
adjustable with an external capacitor, and the accuracy is ±16%( 1). When the supply voltage becomes higher
than the released voltage, the reset state will be maintained during the delay time. The output type of the reset
is selectable, Nch open-drain, or CMOS.
The time out period of the watchdog timer can be also set with an external capacitor, and the accuracy is
±33%(1). There is a function to stop supervising clock by the watchdog timer (INH function). There are another
4 products by the difference of packages and the function of voltage detector and watchdog timer.
The package of R5106N is SOT-23-6.

All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the recommended
operating conditions, even if when they are used over such ratings by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended

Operating Description
(1) When the power supply, VDD pin voltage becomes more than the released voltage (+VDET), after the
released delay time (or the power on reset time tPLH), the output of RESETB becomes "H" level.
(2) When the SCK pulse is input, the watchdog timer (WDT) is cleared, and CT pin mode changes from the
discharge mode to the charge mode. When the CT pin voltage becomes higher than Vref2H, the mode will
change into the discharge mode, and next watchdog time count starts.
(3) Unless the SCK pulse is input, WDT will not be cleared, and during the charging period of CT pin,
RESETB="L".
(4) When the VDD pin becomes lower than the detector threshold voltage (-VDET), RESETB outputs "L".
(5) If "L" signal is input to the INH pin, the RESETB outputs "H", regardless the SCK clock state.
(6) During the "L" period of INH pin, the voltage detector monitors the supply voltage.
(7) When the signal to the INH pin is set from "L" to "H", the watchdog starts supervising the system clock, or
charge cycle to the CT pin starts, the capacitor connected to the CT pin is charged with the current of setting
Reset time of WDT.
Watchdog Timeout period/Reset hold time
The watchdog timeout period and reset hold time can be set with an external capacitor to CT pin.
The next equations describe the relation between the watchdog timeout period and the external capacitor
value, or the reset hold time and the external capacitor value.
tWD (s) = 3.1×106×C (F)
tWR (s) = tWD/9
The watchdog timer (WDT) timeout period is determined with the discharge time of the external capacitor.
During the watchdog timeout period, if the clock pulse from the system is detected, WDT is cleared and the
capacitor is charged. When the charge of the capacitor completes, another watchdog timeout period starts
again. During the watchdog timeout period, if the clock pulse from the system is not detected, during the next
reset hold time RESETB pin outputs "L".
During the reset time, (while charging the external capacitor) and after starting the watchdog timeout period,
(just after from the discharge of the external capacitor) even if the clock pulse is input during the time period
"tWDI", the clock pulse is ignored.
tWDI (s) = tWD/10
Released Delay Time (Power -on Reset delay time)
The released delay time can be set with an external capacitor connected to the CT pin. The next equation
describes the relation between the capacitance value and the released delay time (tPLH).
tPLH (s) =3.7×106× C (F)
The capacitor connected to CT pin determines tWD, tWR, and tPLH.
When the VDD voltage becomes equal or less than (-VDET), discharge of the capacitor connected to the CT pin
starts. Therefore, if the discharge is not enough and VDD voltage returns to (+VDET) or more, thereafter the delay
time will be shorter than tPLH which is expected.

Minimum Operating Voltage
We specified the minimum operating voltage as the minimum input voltage in which the condition of RESETB
pin being 0.1V or lower than 0.1V. (Herein, pull-up resistance is set as 100kΩ in the case of the Nch open-
drain output type.)
Inhibit (INH) Function
If INH pin is set at "L", the watchdog timer stops monitoring the clock, and the RESETB output will be dominant
by the voltage detector's operation. Therefore, if the supply voltage is set at more than the detector threshold
level, RESETB outputs "H" regardless the clock pulse. INH pin is pulled up with a resistor (TYP.110kΩ)
internally.
RESETB Output
RESETB pin's output type is selectable either the Nch open-drain output or CMOS output. If the Nch open-
drain type output is selected, the RESETB pin is pulled up with an external resistor to an appropriate voltage
source.
Clock Pulse Input
Built-in watchdog timer is cleared with the SCK clock pulse within the watchdog timeout period.

TECHNICAL NOTES
When connecting resistors to the device’s input pin
When connecting a resistor (R1) to an input of this device, the input voltage decreases by [Device’s
Consumption Current] x [Resistance Value] only. And, the cross conduction current(1), which occurs when
changing from the detecting state to the release state, is decreased the input voltage by [Cross Conduction
Current] x [Resistance Value] only. And then, this device will enter the re-detecting state if the input voltage
reduction is larger than the difference between the detector voltage and the released voltage.
When the input resistance value is large and the VDD is gone up at mildly in the vicinity of the released voltage,
repeating the above operation may result in the occurrence of output.
As shown in Figure A/B, set R1 to become 100kΩ or less as a guide, and connect CIN(2) of 0.1μF and more to
between the input pin and GND. Besides, make evaluations including temperature properties under the actual
usage condition, with using the evaluation board like this way. As result, make sure that the cross conduction
current has no problem.
