This surface-mount supervisory circuit monitors a single voltage with a threshold of 4V, featuring adjustable undervoltage detection at 3.9V and overvoltage detection at 4.1V. It operates across a supply voltage range of 1.1V to 5.5V and provides an active-high reset with a 1.2s timeout. The component includes a watchdog timer and a totem-pole output, with a low operating supply current of 7µA. Packaged in a 5-pin SOT-23, this lead-free, RoHS-compliant device is suitable for applications requiring reliable power monitoring and system reset.
