R5107G SERIES
AEC-Q100 Compliant
Microprocessor Supervisory Circuit with Manual Reset for Automotive Applications
NO.EC-170-180222
OUTLINE
The R5107G 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
1)
adjustable with an external capacitor, and the accuracy is ±16% (R5107Gxx1x-TR-JE: −40°C ≤ Ta ≤ 105°C) ( .
When the supply voltage becomes 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
1)
±33%( .
The function to stop supervising clock by the watchdog timer (INH function) and manual reset function are built
in this IC. There are another 4 products by the difference of packages and the function of voltage detector and
watchdog timer. The package of R5107G is SSOP-8G.

RECOMMENDED OPERATING CONDITIONS
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 conditions.

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 is cleared, and CTW pin mode changes from the discharge
mode to the charge mode. When the CTW 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 CTW pin,
RESETB="L".
(4) When the VDD pin becomes lower than the detector threshold voltage (-VDET), RESETB outputs "L" after the
tPHL.
(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 CTW pin starts, the capacitor connected to the CTW pin is charged with the current of
setting Reset time of WDT.
(8) If "L" signal is input to the MR pin, the RESETB outputs "L" after the tMR, regardless the SCK clock state
and VDD voltage.
(9) When the signal to the MR pin is set from "L" to "H", the RESETB outputs "H" after the tPLH, the watchdog
starts supervising the system clock.
Watchdog Timeout period/Reset hold time
The watchdog timeout period and reset hold time can be set with an external capacitor to CTW 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 CD 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 CD pin determines tWD, tWR, and tPLH.
When the VDD voltage becomes equal or less than (-VDET), discharge of the capacitor connected to the CD 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.)

R5107G
NO.EC-170-180222
Manual Reset (MR) Function
By setting MR pin as "L", the output of RESETB can be forced to set "L". After pull-down the MR pin to "L", the
delay time (tMR) to the output "L" from RESETB is 1µs as maximum. MR pin is pulled-up via the built-in resistor.
(Typ. 110kΩ ). If MR pin voltage > VDD voltage, a current flows into MR pin. However, the current value is limit
by the pull-up resistor, therefore there is not bad impact on the operation. When the "L" signal is input to MR
pin, the discharge of CD pin capacitor (CD) starts. If the term of "L" for MR pin is short, CD will not be discharged
enough. As a result, the delay time after setting "H" for MR pin will be shorter than expected. Because of this,
confirm the operation under the same conditions as users' applications. For example, in case of CD is set at
0.1µF, and the condition to maintain the delay time value after MR pin's returning to "H", is described as the
minimum "L" term of MR pin, or 150µs. When MR input pulse (tMRW) is less than 3.0µs, output delay time (tPLH)
might not exist.

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.
