SGM890B/SGM891B Voltage Detector with Separated Sense Pin and Delay Capacitor Pin
GENERAL DESCRIPTION
The SGM890B and SGM891B are low-power and high-accuracy voltage detectors. The adjustable threshold range is 0.8V to 5.0V with increments of 0.1V, which greatly provides application flexibility.
Since the sense pin (VSEN) of the device is separated from the power supply pin, it can monitor other power supplies. And when the monitored power supply voltage drops to 0V, the device can also maintain the detection state.
In addition, the CD pin of SGM890B has an external capacitor connected to GND, which can adjust the release delay time. Consequently delay time can be set to more than 1s when...
