Micropower Monitoring Capability


Posted on Mar 11, 2013

The LTC®1541 combines a micropower amplifier, comparator and 1.2V reference in an 8-pin package. The part operates from a single 2.5V to 12.6V supply with typical supply current of 5mA. Both op amp and comparator feature a common mode input voltage range that extends from the negative supply to within 1.3V of the positive supply. The op amp output stage swings from rail-to-rail. Figure 1 lists additional features along with a block diagram of the device.



The comparator (C) monitors the battery voltage via the 2M1M divider and compares it to the 1.2V reference. A battery voltage above 3.6V holds Cs output high, biasing Q2 on and maintaining the small potential at As
