Description
The V6150 offers a high level of integration by voltage
monitoring and software monitoring in an 8 lead
package. A comparator monitors the voltage applied at
the V
input comparing it with an internal 1.5 V
reference. The power-on reset function is initialized after
V
reaches 1.5 V and takes the reset output inactive
after T
depending of external resistance. The reset
output goes active low when the V
voltage is less than
1.5 V. The RES and EN outputs are guaranteed to be in
a correct state for a supply voltage as low as 1.2 V. The
watchdog function monitors 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 control functions
being activated until software has successfully cleared
the watchdog three times. Such a security could be
used to prevent motor controls being energized on
repeated resets of a faulty system.
