R EM MICROELECTRONIC - MARIN SA V6300 V6301 Ultra Low Power 3-Pin Power-On Reset IC Description Features The V6300 and V6301 are CMOS devices which monitor Clear microprocessor restart after power up the supply voltage of any electronic system, and generate Processor reset at power down the appropriate Reset signal. The threshold defines the Reset output guaranteed down to VDD = 1V minimum allowed voltage which guarantees the good Low power consumption: typ. 3µA at VDD = 5V functionality of the system. As long as VDD stays upside this voltage level, the output stays inactive. If VDD drops below -40 to +85°C temperature range VTH, the output gets active. When VDD rises above VTH, the Power-on reset time: output remains active for an additio
