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

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.

Top marking is standard from 2006. 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.
