Description

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 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.

1. A resistor is required for open drain output type only. A 10 kΩ pull-up is sufficient in most applications.

2. Capacitor CREF is mandatory on VREF output (even if VREF is not used). Capacitor value of 1 µF is recommended.
