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

TH, the output gets active. When VDD rises above VTH, the
output remains active for an additional 290 ms (V6301) or
50 ms (V6300). This allows the system to stabilize before
getting fully active. The threshold voltage may be obtained
in different versions: 2.0V, 2.4V, 2.8V, 3.5V, 4.0V, 4.5V.
