RR1220P-303-D Datasheet *1: Tc measured point is shown in page OUTLINE DRAWING. *2: Typical value is measured by using Shin-etsu Silicone "G-746". *3: If you use this value , Rth(f-a) should be measured just under the chips. (D IE,VEC,trr,Qrr & die/dt represent characteristics of the anti-parallel,emitter to collector free-wheel diode (FWDi). Pulse width and repetition rate should be such that the device junction temp.(T) dose not exceed Tjmax rating Junction temperature (Tj) should not increase beyond isooc. Pulse width and repetition rate should be such as to cause neglible temperature rise.

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 lC 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).
