STMicroelectronics STM6717/6718/6719/6720/STM6777/6778/6779/6780 Datasheet
The STM6717/18/19/20 and STM6777/78/79/80 supervisors are a family of low-voltage, low-supply current processor supervisors designed to monitor two or three system power supply voltages. They are targeted at applications such as set-top boxes, portable battery-powered systems, networking, and communication systems.
These devices feature push-button-type manual reset inputs (MR) and, for the STM6777/78/79/80 variants, an optional delayed manual reset input (MRC). Two of the three monitored supplies (VCC1 and VCC2) have fixed, factory-trimmed reset thresholds, while the third voltage is monitored using an externally adjustable RSTIN threshold. When any monitored voltage drops below its threshold or MR is asserted low, the RST output is driven low.
