Data Sheets:
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 interruptions. 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.
- 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 oscillations
- On-chip inverting op amp for negative voltage
- Open-collector output logic or expandability
- Operation from 4.5V to 40V supply
