R5104V SERIES Microprocessor power management with Watchdog Timer NO.EA-136-070201 OUTLINE The R5104V Series are high voltage tolerance CMOS-based microprocessor power management ICs with high accuracy output voltage and detector threshold and with ultra low supply current. Each of these ICs consists of a voltage regulator, a voltage detector and a watchdog timer. Thus, the R5104V Series have the function of a power management for microprocessor, a monitor of the voltage of a power source and a microprocessor supervisor. The built-in voltage regulator with an external driver transistor can supply Min.1A current to a system. Therefore these ICs are very suitable for various power supply systems for microprocessors. The output voltage is monitored by the voltage detector which is built-in these ICs. The built-in voltage detector has an output delay function and the delay time can be set by an external capacitor (CD). The output voltage and the detector threshold voltage can be set individually for each IC by laser trimming. Furthermore, when a microprocessor works incorrectly, the watchdog timer which checks over microprocessor generates reset signals intermittently to prevent a whole system from being malfunction. The timeout periods for watchdog and reset can also be set individually by an external capacitor (CTW). There are two kinds of power down function: "A" version turns off the supervisor of clock input for the watchdog timer, while the "B" version turns off all the circuits and realizes the standby mode.

Operational Ratings (Electrical Characteristics) Application circuits of semiconductors should be designed with operating within the operational ratings of the semiconductors. Even the noise or surge, if their level is beyond the operational ratings, normal operation of the semiconductor may not be expected. If the application circuits make the semiconductor operate beyond the condition of operational ratings, the quality assurance level of the semiconductor cannot be maintained. Absolute Maximum Ratings Absolute maximum ratings are threshold limit values that must not be exceeded even for any moment under any conditions. More over, such values for any two or more items of the ratings must not be reached simultaneously. Operation above these absolute maximum ratings may cause degradation or fatal damage to the device. These mean stress ratings and do not necessarily imply functional operation below these limits. 4 R5104V ELECTRICAL CHARACTERISTICS • (Unless otherwise specified, VIN=CE=VISENSE=12V, IOUT=100mA, CCTW=0.1µF, CD=0.01µF) R5104VxxxA(Overall) Symbol Topt=25°C Item Conditions Min.

When the watchdog timer is enabled (CE="H"), the output of the internal regulator and SCK input pulse are supervised, while the watchdog timer is disabled (CE="L"), only the regulator is supervised. R5104VxxxB (Standby Function) Since the standby function is included in the R5104VxxxB, the consumption current of the system can be reduced. The supply current at the standby mode is very small, typically 0.1µA. Output Delay Time Setting of the built-in voltage detector The released delay time from reset of the voltage detector (tPLH) can be calculated with the external capacitor value CD and the next formula. tPLH = VTCD x CD/ICD (S) On the other hand, output delay time for detecting voltage (tPHL) is not specified, the time depends on the capacitance value of CD.

Therefore connect a 10µF or more value capacitor between VOUT and GND. The ESR range of the output capacitor should be approximately 1Ω to 10Ω. The fluctuation and the noise of the supply voltage, or a drastic change of the output voltage by the load transition of the regulator might be the reason of the mis-operation of the watchdog timer. If the SCK input pulse frequency is beyond 10kHz, or if the capacitance value of CTW pin is large, the watchdog timer is easily affected by the fluctuation or noise of the supply voltage, or the fluctuation of the regulator output voltage, and it may cause an unstable operation. If VIN (supply voltage) may swing momentary, the regulator output is also swings. If the output of the voltage regulator becomes lower than detector voltage threshold, the built-in detector may generate the reset signal. Built-in over-current limit works as monitoring the sink current of EXT pin and limits the current. Considering the over-current of the corrector current caused by short of EXT pin and GND externally, set a resistor between EXT pin and the base of the external driver transistor to limit the base current. Use a 100pF or more value capacitor for CTW pin. Use a 10pF or more capacitor for CD pin. A capacitor must be connected to CD pin to use R5104VxxxA. To avoid the mis-operation, during watchdog timer monitoring time, there is some ignoring time against clock pulse. Therefore, during the ignoring time, input clock pulse (rising edge trigger) is ignored. The ignoring time VREF2H is approximately as follows: The time interval for CTW pin voltage from VREF2H to VREF2H−(VREF2H−VREF2L)/4 17 PACKAGES INFORMATION • PE-SSOP-10-0707 SSOP-10 Unit: mm PACKAGE DIMENSIONS 3.1±0.2 1.15±0.1 11 2 3 4 5 0.55TYP. 0.15 +0.1 −0.05 6.4±0.2 4.4±0.2 10 9 8 7 6 0.5 0.1±0.05 0° 0.1 0.2±0.1 0.5±0.2 0.1 M 4.0±0.1 3.7 5.5±0.05 2.0±0.05 6.9 8.0±0.1 2.7MAX. 1.6±0.1 E2 User Direction of Feed TAPING REEL DIMENSIONS (1reel=2000pcs) 17.4±1 ∅13±0.2 13.4±1 ∅100±1 21±0.8 ∅254±2 2±0.5 12.0±0.3 1.5 +0.1 0 0.3±0.1 1.75±0.1 TAPING SPECIFICATION 10° PACKAGES INFORMATION PE-SSOP-10-0707 POWER DISSIPATION (SSOP-10) This specification is at mounted on board.
