Power Voltage Monitoring IC
with Watchdog Timer
MB3793-30A
■ DESCRIPTION
The MB3793 is an integrated circuit to monitor power voltage; it incorporates a watchdog timer.
A reset signal is output when the power is cut or falls abruptly. When the power recovers normally after resetting,
a power-on reset signal is output to microprocessor units (MPUs). An internal watchdog timer with two inputs for
system operation diagnosis can provide a fall-safe function for various application systems.
There is also a mask option that can detect voltages of 4.9 V to 2.4 V in 0.1-V steps.
■ FEATURES
• Precise detection of power voltage fall: ± ±2.5%
• Detection voltage with hysteresis
• Low power dispersion: ICC = 31 µA (reference)
• Internal dual-input watchdog timer
• Watchdog-timer halt function (by inhibition pin)
• Independently-set watchdog and reset times
• Three types of packages (SOP-8pin : 2 types, SSOP-8pin : 1 type)
■ APPLICATION
• Arcade Amusement etc.

■ BLOCK DESCRIPTION
1. Comp. S
Comp. S is a comparator with hysteresis to compare the reference voltage with a voltage (VS) that is the result
of dividing the power voltage (VCC) by resistors 1 and 2. When VS falls below 1.24 V, a reset signal is output.
This function enables the MB3793 to detect an abnormality when the power is cut or falls abruptly.
2. Output circuit
The output circuit contains a RESET output control comparator that compares the voltage at the CTP pin to the
threshold voltage to release the RESET output if the CTP pin voltage exceeds the threshold value.
Since the reset (RESET) output buffer has CMOS organization, no pull-up resistor is needed.
3. Pulse generator
The pulse generator generates pulses when the voltage at the CK1 and CK2 clock pins changes to High from
Low level (positive-edge trigger) and exceeds the threshold voltage; it sends the clock signal to the watchdog
timer.
4. Watchdog timer
The watchdog timer can monitor two clock pulses. Short-circuit the CK1 and CK2 clock pins to monitor a single
clock pulse.
5. Inhibition pin
The inhibition (INH) pin forces the watchdog timer on/off. When this pin is High level, the watchdog timer is
stopped.
6. Logic circuit
The logic circuit contains flip-flops.
Flip-flop RSFF1 controls the charging and discharging of the power-on reset hold time setting capacitor (CTP).
Flip-flop RSFF2 turns on/off the circuit that accelerates charging of the power-on reset hold time setting capacitor
(CTP) at a reset. The RSFF2 operates only at a reset; it does not operate at a power-on reset when the power
is turned on.

Note : The MB3793 watchdog timer monitors Clock1 (CK1) and Clock2 (CK2) pulses alternately.
When a CK2 pulse is detected after detecting a CK1 pulse, the monitoring time setting capacity
(CTW) switches to charging from discharging.
When two consecutive pulses occur on one side of this alternation before switching, the second
pulse is ignored.
In the above figure, pulse *1 and *2 are ignored.

■ OPERATION SEQUENCE
1. Positive clock pulse input
Refer to “1. Basic operation (positive clock pulse)” under “■ DIAGRAM.”
2. Negative clock pulse input
Refer to “2. Basic operation (negative clock pulse)” under “■ DIAGRAM.”
The MB3793 operates in the same way whether it inputs positive or negative pulses.
3. Clock monitoring
To use the MB3793 while monitoring only one clock, connect clock pins CK1 and CK2.
Although the MB3793 operates basically in the same way as when monitoring two clocks, it monitors the clock
signal at every other input pulse.
Refer to “3. Single-clock input monitoring (positive clock pulse)” under “■ DIAGRAM.”
4. Description of Operations
The numbers given to the following items correspond to numbers (1) to (13) used in “■ DIAGRAM.”
(1) The MB3793 outputs a reset signal when the supply voltage (VCC) reaches about 0.8 V (VCCL)
(2) If VCC reaches or exceeds the rise-time detected voltage VSH, the MB3793 starts charging the power-on
reset hold time setting capacitor CTP. At this time, the output remains in a reset state. The VSH value is
3.07 V (Typ) .
(3) When CTP has been charged for a certain period of time TPR (until the CTP pin voltage exceeds the
threshold voltage (Vth) after the start of charging), the MB3793 cancels the reset (setting the RESET pin
to “H” level from “L” level).
The Vth value is about 2.4 V with VCC = 3.3 V
The power-on reset hold time tPR is set with the following equation:
.
tPR (ms) = A × CTP (µF)
.
The value of A is about 750 with VCC = 3.3 V. The MB3793 also starts charging the watchdog timer
monitor time setting capacitor (CTW).
(4) When the voltage at the watchdog timer monitor time setting pin CTW reaches the “H” level threshold
voltage VH, the CTW switches from the charge state to the discharge state.
The value of VH is always about 1.24 V regardless of the detected voltage.
(5) If the CK2 pin inputs a clock pulse (positive edge trigger) when the CTW is being discharged in the
CK1-CK2 order or simultaneously, the CTW switches from the discharge state to the charge state.
The MB3793 repeats operations (4) and (5) as long as the CK1/CK2 pin inputs clock pulses with the
system logic circuit operating normally.
(6) If no clock pulse is fed to the CK1 or CK2 pin within the watchdog timer monitor time tWD due to some
problem with the system logic circuit, the CTW pin is set to the “L” level threshold voltage VL or less and
the MB3793 outputs a reset signal (setting the RESET pin to “L” level from “H” level).
The value of VL is always about 0.24 V regardless of the detected voltage.
The watchdog timer monitor time tWD is set with the following equation:
.
tWD (ms) = B × CTW (µF)
.
The value of B is hardly affected by the power supply voltage; it is about 1600 with VCC = 3.3 V.
(Continued)
12
MB3793-30A
(Continued)
(7) When a certain period of time tWR has passed (until the CTP pin voltage reaches or exceeds Vth again
after recharging the CTP), the MB3793 cancels the reset signal and starts operating the watchdog timer.
The watchdog timer monitor reset time tWR is set with the following equation:
.
tWR (ms) = D x CTP (µF)
.
The value of D is 55 with VCC = 3.3 V.
The MB3793 repeats operations (4) and (5) as long as the CK1/CK2 pin inputs clock pulses. If no clock
pulse is input, the MB3793 repeats operations (6) and (7).
(8) If VCC is lowered to the fall-time detected voltage (VSL) or less, the CTP pin voltage decreases and the
MB3793 outputs a reset signal (setting the RESET pin to “L” level from “H” level).
The value of VSL is 3.0 V (Typ) .
(9) When VCC reaches or exceeds VSH again, the MB3793 starts charging the CTP.
(10) When the CTP pin voltage reaches or exceeds Vth, the MB3793 cancels the reset and restarts operating
the watchdog timer. It repeats operations (4) and (5) as long as the CK1/CK2 pin inputs clock pulses.
(11) Making the inhibit pin active (setting the INH pin to “H” from “L”) forces the watchdog timer to stop
operation.
This stops only the watchdog timer, leaving the MB3793 monitoring VCC (operations (8) to (10)).
The watchdog timer remains inactive unless the inhibit input is canceled.
The inhibition (INH) pin must be connecting a voltage of more low impedance, to evade of the noise.
(12) Canceling the inhibit input (setting the INH pin to “L” from “H”) restarts the watchdog timer.
(13) The reset signal is output when the power supply is turned off to set VCC to VSL or less.

■ NOTES ON USE
• Take account of common impedance when designing the earth line on a printed wiring board.
• Take measures against static electricity.
- For semiconductors, use antistatic or conductive containers.
- When storing or carrying a printed circuit board after chip mounting, put it in a conductive bag or container.
- The work table, tools and measuring instruments must be grounded.
- The worker must put on a grounding device containing 250 kΩ to 1 MΩ resistors in series.
• Do not apply a negative voltage.
- Applying a negative voltage of −0.3 V or less to an LSI may generate a parasitic transistor, resulting in
malfunction.
