Typical Operating Configuration
Description
The V6130 offers a high level of integration by voltage
monitoring and software monitoring in an 8 lead pack-
age. A comparator monitors the voltage applied at the VIN
input comparing it with an internal 1.17 V reference. The
power-on reset function is initialized after VIN reaches 1.17
V and takes the reset output inactive after TPOR depending
of external resistance. The reset output goes active low
when the VIN voltage is less than 1.17 V. The RES and EN
outputs are guaranteed to be in a correct state for a sup-
ply voltage as low as 1.2 V. The watchdog function moni-
tors software cycle time and execution. If the software
clears the watchdog too quickly (incorrect cycle time) or
too slowly (incorrect execution) it will cause the system to
be reset. The system enable output prevents critical con-
trol functions being activated until software has success-
fully cleared the watchdog three times. Such a security
could be used to prevent motor controls being energized
on repeated resets of a faulty system.

Stresses above these listed maximum ratings may cause
permanent damage to the device. Exposure beyond
specified operating conditions may affect device reliabil-
ity or cause malfunction.
Handling Procedures
This device has built-in protection against high static volt-
ages or electric fields; however, anti-static precautions
must be taken as for any other CMOS component. Unless
otherwise specified, proper operation can only occur
when all terminal voltages are kept within the supply volt-
age range. Unused inputs must always be tied to a de-
fined logic voltage level.

1) The maximum operating temperature is confirmed by sampling
at initial device qualification. In production, all devices are
tested at +85 °C. On request devices tested at +125 °C can
be supplied.
2) A 100 nF decoupling capacitor is required on the supply
voltage VDD for stability.
3) RES must be pulled up externally to VDD event if it is unused.
(Note: RES and EN are used as inputs by EM test.)
