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 V_DD stays upside this voltage level, the output stays
inactive. If V_DD drops below V_TH, the output gets active.
The threshold voltage may be obtained in different versions:
2.6V, 3.0V, 3.7V and 4.4V.
Features
! SOT-23 and TO-92 package
! Reset output state guaranteed down to V_DD = 1V @
25°C
! Low supply current: stays stable during switching
versions B, N, N:
typ. 19µA at V_DD = 5V
other versions:
typ. 38µA at V_DD = 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
! TTL output compatibility
