Sales Briefcase
  • 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 (PBand 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 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.

    Key Features

    • Operating voltage 1.6 V to 5.5 V
    • Low standby current of 0.6 μA
    • Adjustable Smart Resetassertion delay time driven by external CSRD
    • Power-up duration determined primarily by push-button press (STM6600) or by fixed time period, tON_BLANK(STM6601)
    • DebouncedPBand SRinputs
    • PBand SRESD 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 Resetor power-down driven by push-button
    • Precise 1.5 V voltage reference with 1% accuracy
    • Industrial operating temperature –40 to +85 °C
    • Available in TDFN12 2 x 3 mm package
