The SGM861 is a high precision voltage supervisor with over-voltage (OV) and under-voltage (UV) monitor in a small package. It is very suitable for low-voltage systems that need extremely small tolerance. To prevent error events when the monitored signal is within the normal range, this device integrates very small threshold hysteresis, as well as built-in deglitch capability and noise immunity.
The SGM861 provides UV and OV threshold monitor function internally so that external resistor divider is not needed any more. As a result, overall cost and peripheral circuit size are reduced, and system reliability can be enhanced. Two factory-set reset delay time can be selected when CT pin is floating or pulled up to VDD through a resistor. The reset delay time can also be adjusted by placing a capacitor between CT pin and GND. The VDD pin and the SENSE pin are separated to provide redundancy for high reliability. The SGM861 has low quiescent current of 1.24μA (TYP). This device is recommended to be used in industrial automation and process control, or conditions that monitor voltages for UV and OV threshold with very high precision.
The SGM861 is available in a Green TDFN-1.5×1.5-6L package. It operates over the junction temperature range of -40℃ to +125℃.
