Ultra Low Pow er 3-Pin Voltage Surveillance with Time-out
Description
The V6300 is a CMOS device which monitors the supply
voltage of any electronic system, and generates 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
VTH, the output gets active. W hen VDD rises above VTH, the
output remains active for an additional 50ms (typ.). 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.
Features
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
On-chip oscillator
No external components required
Push-pull or Open drain output
TO-92 and SOT-23 5L packages
Pin compatible with DS 1233 A in TO-92
Applications
All microprocessor applications where an automatic restart
is required:
Computer electronics
White / Brown goods
Automotive electronics
Industrial electronics
Telecom systems
Hand-held systems

specified operating conditions may affect device reliability or
cause malfunction.
Handling Procedures
This device has built-in protection against high static
voltages or electric fields; however, it is advised that normal
precautions be taken as for any other CMOS component.
Unless otherwise specified, proper operation can only occur
when all terminal voltages are kept within the voltage range.
