Typical Operating Configuration
VDDVDDVDDRESorRESRESorRESV6301VSSMicro-processorVSSGNDDescription
The V6301 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. When VDD rises above VTH, the output remains active for an additional 290 ms (typ.). This allows the system to stabilize before getting fully active. The threshold voltage may be obtained in different versions: 2.0 V, 2.4 V, 2.8 V, 3.5 V, 4.0 V, 4.5 V.

Stresses above these listed maximum ratings may cause permanent damage to the device. Exposure beyond 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, 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 voltage range.
