SRC0 Smart Reset™ SwitchSTMicroelectronics SRC0 Smart Reset™ Switch is designed to monitor the state of connected push-button(s) as well as sufficient supply voltage. An enable output controls power for the application through the MOSFET transistor, DC-DC converter, regulator, etc. If the supply voltage is above a precise voltage threshold, the enable output can be asserted by a simple press of the button. Factory-selectable supply voltage thresholds are determined by highly accurate and temperature-compensated references. An interrupt is asserted by pressing the push-button during normal operation and can be used to request a system power-down. The interrupt is also asserted if undervoltage is detected. By a long push of one button (PB) or two buttons (PB and SR) either a reset is asserted or power for the application is disabled depending on the option used. The device also offers additional features such as precise 1.5 V voltage reference with very tight accuracy of 1%, separate output indicating undervoltage detection and separate output for distinguishing between interrupt by push-button or undervoltage. The SRC0 Smart Reset Switch consumes very low current of 6 µA during normal operation and only 0.6 µA current during standby.
