Voltage Detector with Separated Sense Pin and Delay Capacitor Pin

The SGM890B and SGM891B are low-power and high-accuracy voltage detectors. The adjustable threshold range is 0.8V to 5V with increments of 0.1V, which greatly provides application flexibility.

Since the sense pin (VSEN) of the devices is separate 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 the delay capacitor (CD) is 1μF. These devices are very suitable for applications in power sequencing, reset sequencing and power switching.

The SGM890B and SGM891B are available in a Green SOT-23-5 package. They are specified over the -40 to +125 operating temperature range.
