POWER-VOLTAGE MONITORING IC WITH WATCHDOG TIMER
MB3793-45
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 fail-safe function for various application systems. Model No. MB3793-45 Marking Code 3793-7 Detection voltage 4.5 V

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 " TIMING DIAGRAM."
2. Negative clock pulse input
Refer to "2. Basic operation (negative clock pulse)" under " TIMING 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 " TIMING DIAGRAM."
4. Description of Operations
The numbers given to the following items correspond to numbers (1) to (13) used in " TIMING 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 4.60 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 3.6 V with VCC = 5.0 V The power-on reset hold time tPR is set with the following equation: tPR (ms) . . A x CTP ( F) = The value of A is about 1300 with VCC = 5.0 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 x CTW ( F) + C x CTP ( F) = The value of B is hardly affected by the power supply voltage; it is about 1500 with VCC = 5.0 V. The value in C is about 3 which is tremendously smaller than the value in B. For this reason, it is possible to simplify the formula as below when CTP/CTW . . 10 or less. = tWD (ms) . . B x CTW ( F) =
DS04-27405-2E

MB3793-45
(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 ( F) = The value of D is 100 with VCC = 5.0 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 4.50 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.

USAGE PRECAUTION
1. Do not configure the IC over the maximum ratings
If the lC is used over the maximum ratings, the LSl may be permanently damaged. It is preferable for the device to normally operate within the recommended usage conditions. Usage outside of these conditions can have a bad effect on the reliability of the LSI.
2. Use the devices within recommended operating conditions
The recommended operating conditions are under which the LSl is guaranteed to operate. The electrical ratings are guaranteed when the device is used within the recommended operating conditions and under the conditions stated for each item.
3. Printed circuit board ground lines should be set up with consideration for common impedance 4. Take appropriate measures against static electricity
* * * * Containers for semiconductor materials should have anti-static protection or be made of conductive material. After mounting, printed circuit boards should be stored and shipped in conductive bags or containers. Work platforms, tools, and instruments should be properly grounded. Working personnel should be grounded with resistance of 250 k to 1 M between body and ground.
5. Do not apply negative voltages
The use of negative voltages below -0.3 V may create parasitic transistors on LSI lines, which can cause malfunctions.
