The STM6601CA2BDM6F is a smart Pushbutton On/Off Controller with pull-up internal resistor on Smart Reset? input and power-on lockout. The STM6600-01 device monitors the state of connected pushbutton as well as sufficient supply voltage. An enable output controls power for the application through the MOSFET transistor, DC-DC converter and regulator. 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 under-voltage 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.
- Adjustable Smart Reset? assertion delay time driven by external CSRD
- Debounced /PB and /SR inputs
- /PB and /SR ESD inputs withstand voltage up to ±15kV (air discharge) ±8kV (contact discharge)
- Secure start-up, interrupt, Smart Reset? or power-down driven by pushbutton
- Precise 1.5V voltage reference with 1% accuracy
- 0.6μA Low standby current
