3. For the STM6601 the processor has to confirm the proper power-on during the fixed time period, t
feature prevents the user from turning on the system when there is a faulty power switch or an unresponsive

Description
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 (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 device consumes very low current of 6 µA during normal operation and only 1 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. (see
