www.DataSheet4U.com 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.
