R EM MICROELECTRONIC - MARIN SA V6301 Ultra Low Power 3-Pin Voltage Surveillance with Time-out Description Applications 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: 2.0V, 2.4V, 2.8V, 3.5V, 4.0V, 4.5V.

Top marking with 3 characters is kept as information since it was used until 2002. Where # refers to the lot number (EM internal reference only) Traceability for small packages Due to the limited space on the package surface, the bottom marking contains a limited number of characters that provide only partial information for lot traceability. Full information for complete traceability is however provided on the packing labels of the product at delivery from EM: It is highly recommended that the customer insures full lot traceability of EM product in his final product.
