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 f alls abruptly. When the power recov ers 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 v oltage (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 v oltage 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 buff er has CMOS organization, no pull-up resistor is needed.
3. Pulse generator
The pu ls e g ene rator g ene rates pulses when the voltage at the CK1 an d CK 2 c lock pin s ch ang es to High from
Low leve l (posit ive-edg e trigger ) and exceeds the thres hold voltage; it se nds 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. Inhibit ion pi n
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 RSFF 2 op erate s only at a re set ; it doe s no t opera te at a power-on re se t when the power
is tur ne d 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 SEQ UE NCE
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 e xceeds 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 tim e setting ca pacitor (CTW).
(4) When the voltage at the watchdog timer monitor time setting pin CTW reache s 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” le vel 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.

=
..
=
MB3793-30A
13
(Continued)
(7) When a c ertain pe riod of t ime tWR has passed (until the CTP pin v oltage 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 volta ge (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 ) W h en VCC reaches or exceeds VSH again, the MB3 793 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.
