| R EM MICROELECTRONIC - MARIN SA V6340 Ultra Low Cost 3-Pin Microprocessor Reset Description The V6340 monitors the supply voltage of any electronic system, and generates the appropriate Reset signal. The threshold must be chosen to 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. The threshold voltage may be obtained in different versions: 2.6V, 3.0V, 3.7V and 4.4V. Applications Applications needing a voltage detection: ! Computer electronics ! White / Brown goods ! Automotive electronics ! Industrial electronics ! Telecom systems ! Hand-held systems Features ! SOT-23 and TO-92 package ! Reset output state guaranteed down to VDD = 1V @ 25C ! Low supply current: stays stable during switching versions B, N, N: typ. 19A at VDD = 5V other versions: typ. 38A at VDD = 5V ! 2.5% voltage threshold accuracy ! High noise immunity ! No external components required ! Push-pull or Open drain output ! Pin compatible with MAX 809 in SOT-23, by appropriate layout on PCB ! Pin compatible with MC 33164 in TO-92 !

No bottom marking exists. Where ## refers to the lot number (EM internal reference only) Top marking with 4 characters is standard from 2003. For lead-free/green mold (RoHS) parts, the first letter of top marking with 4 characters begins with letter "B" instead of letter "A". Bottom marking indicates the lot number. 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 Copyright (c) 2005, EM Microelectronic-Marin SA 03/06 - rev.K 7 www.emmicroelectronic.com R V6340 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.
