Description
Key Features:
" Monitors four DC voltages and the AC line
" Precision 2.5V ±1% low-drift reference
" Fault tolerance adjustable from ±5% to ±40%
" ±3% trip threshold tolerance over temperature
" Separate 10mA, 40V overvoltage, undervoltage
and AC line fault outputs
" Fault delay programmable with a single capacitor
" 30mV comparator hysteresis to prevent oscilla-tions
" On-chip inverting op amp for negative voltage
" Open-collector output logic or expandability
" Operation from 4.5V to 40V supply
The SG1548 is an integrated circuit capable of monitoring up to four positive
DC supply voltages simultaneously for overvoltage and undervoltage fault
conditions. An on-chip inverting op amp also allows monitoring one negative
DC voltage. The fault tolerance window is accurately programmable from ±5%
to ±40% using a simple divider network on the 2.5V reference. A single
external capacitor sets the fault indication delay, eliminating false outputs due
to switching noise, logic transition current spikes, and short-term AC line
interrup-tions. An additional comparator referenced to 2.5V allows the AC line
to be monitored for undervoltage conditions or for generation of a line clock.
The comparator can also be used for programmable undervoltage lockout in a
switching power supply. Uncommitted collector and emitter outputs permit both
inverting and non-inverting operation. External availability of the precision 2.5V
reference and open-collector logic outputs permit expansion to monitor
additional voltage using available open-collector quad comparators.
