The STM6600-01 devices 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 (PBandSR) 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 device consumes very low current of 6 µA during normal operation and only 0.6 µA current during standby.The STM6600-01 is available in the TDFN12 package and is offered in several options among features such as selectable threshold, hysteresis, timeouts, output types, etc.Operating voltage 1.6 V to 5.5 VLow standby current of 0.6 µAAdjustable Smart Reset™assertion delay time driven by external CSRDPower-up duration determined primarily by push-button press (STM6600) or by fixed time period, tON_BLANK(STM6601)DebouncedPBandSRinputsPBandSRESD inputs withstand voltage up to ±15 kV (air discharge) ±8 kV (contact discharge)Active high or active low enable output option (ENor EN) provides control of MOSFET, DC-DC converter, regulator, etc.Secure startup, interrupt, Smart Reset™or power-down driven by push-buttonPrecise 1.5 V voltage reference with 1% accuracyIndustrial operating temperature –40 to +85 °CAvailable in TDFN12 2 x 3 mm package
