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 V_IN

input comparing it with an internal 1.17 V reference. The

power-on reset function is initialized after V_INreaches 1.17

V and takes the reset output inactive after T_PORdepending

of external resistance. The reset output goes active low

when the V_INvoltage 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.
