R EM MICROELECTRONIC - MARIN SA V6340 Ultra Low Cost 3-Pin Microprocessor Reset Description Applications 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 needing a voltage detection: Computer electronics White / Brown goods Industrial electronics Telecom systems Hand-held systems Features SOT-23 package Reset output state guaranteed down to VDD = 1V @ 25°C Low supply current: stays stable during switching versions B, H, N: typ. 19µA at VDD = 5V other versions: typ. 38µA 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 TTL output compatibility Pin Assignment Typical Operating Configuration VDD VDD V6340 RES or RES Microprocessor VSS GND Fig. 2 Fig. 1 Copyright © 2008, EM Microelectronic-Marin SA 12/08 – rev.M 1 www.emmicroelectronic.com R V6340 Absolute Maximum Ratings Parameter Voltage at VDD to VSS Minimum voltage at RES or RES Maximum voltage at RES or RES Storage Temperature Range Handling Procedures Symbol VDD Conditions -0.3V to +8V Vmin VSS – 0.3V Vmax VDD + 0.3V TSTO -65°C to +150°C This device has built-in protection against high static voltages or electric fields; however, it is advised that normal precautions be taken as for any other CMOS component. Unless otherwise specified, proper operation can only occur when all terminal voltages are kept within the voltage range.

No bottom marking exists. 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.
