‘99.12.3 Microprocessor power management with Watchdog Timer R5101G Series 12345 Rev. 1.10 - 1 - n OUTLINE The R5101G Series are microprocessor power management ICs with high accuracy output voltage and detector threshold and with ultra low supply current by CMOS process. Each of these ICs consists of a voltage regulator, a voltage detector and a watchdog timer. Thus, the R5101G 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 internal driver transistor can supply typically 50mA current to a system when the voltage difference between input and output is 2V. 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 time period for watching and holding a reset signal of the watchdog timer can also be set individually by an external capacitor(CTW). n FEATURES l Built-in a watchdog timer l Time period for monitoring and generating a reset signal of the watchdog timer can be set by an external capacitor l Watchdog timer can be stopped individually by CE Pin l The output voltage of Voltage Regulator and the detector threshold voltage can be set individually with a step of 0.1V for each IC by laser trim l High Accuracy Output Voltage of Voltage Regulator and Detector Threshold · · · · ±2.5% l Power-on Reset Delay Time can be set by an external capacitor l Output Current · · · · · · · Typ. 50mA (at Vin - Vout = 2V) l Small Package · · · Ultra-mini SSOP-8G (0.65mm pitch ) Refer to Package Dimensions n APPLICATION l Power source for microprocessors n PIN CONFIGURATION CTW CD VDD VOUT SCK GND Reset CE SSOP8G(0.65mm pitch)

Rev. 1.10 - 11 - n OPERATION ¬ When VDD is turned on and Input Voltage reaches Vstart (nearly equal 0.8V), the output of RESET pin becomes “L” level. - An External Capacitor starts to be charged through the CD pin when an Output Voltage of the Voltage Regulator, VOUT, crosses the Released Voltage , +VDET , from Lower to Higher . The VRESET is kept “L” level until Voltage of the CD pin , VCD , reaches to the Vref2H , about 1.0V , and after that the VRESET becomes to “H” level. \\ tPR : Time interval between the timing of starting edge of forcing voltage to VDD pin and the timing of reverse the voltage level of VRESET . tPR can be set by connecting an external capacitor to CD pin, tPR can be calculated as shown below; tPR (ms) » 13000´ CD (mF) ; CD means a value of an external capacitor connected to CD pin. ® When the voltage level of VCD reaches to the Vref2H, the external capacitor starts to be charged through the CTW pin and the watchdog timer begins to operate. ¯ The operation mode for the external capacitor changes from charging mode to discharging mode through CTW pin when the voltage level of CTW pin , VCTW , reaches to the Vref2H. ° While the CTW pin is on the discharging mode, if a clock pulse is entered (synchronous with a rising edge of the pulse), the operation mode of CTW pin changes from charging mode to discharging mode. And the external capacitor connected to CTW pin is charged until its voltage level reaches to Vref2H. ± While the CTW pin is on the discharging mode, if VCTW level drops to Vref2L, about 0.2V without clock pulse to CLK pin, the voltage level of Reset pin becomes from “H” to “L”. \\ Watch Time of the watchdog timer , tWD , : Discharging Time of CTW pin level from Vref2H to Vref2L tWD can be set by connecting an external capacitor to CW pin, tWD can be calculated as shown below; tWD (ms) » 10000´ CW (mF); Cw means a value of an external capacitor connected to Cw pin. ² CTW pin is changed to charging mode from discharging mode when the Reset signal is generated. \\ Reset time of the watchdog timer , tWR , : Time interval between Charging time of the CTW pin from Vref2L to Vref2H. tWR can be calculated by the next equation as shown below; tWR (ms) » tWD/10 ³ The Output Voltage level of Reset pin becomes from “H” to “L”, or a Reset signal is generated when an output voltage of the Voltage Regulator drops to a level at equal or less than -Vdet. ´ The watchdog timer will be halted when a Voltage level of CE pin becomes to “L”. In this case, only the watchdog timer is stopped and monitoring the output voltage is continued. After that, if the voltage level of CE pin becomes to “H”, CTW pin starts to be on charging mode.
