docid15453 rev 12 5/52 stm6600, stm6601 description 51 1 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 fo r the application is disabled depending on the option used. the device also offers additional features su ch as precise 1.5 v voltage reference with very tight accuracy of 1%, separate output indica ting undervoltage detecti on and separate output for distinguishing between interrupt by push-button or undervoltage. the device consumes very low current of 6 a during normal operation and only 0.6 a current during standby. the stm6600-01 is available in the tdfn12 pa ckage and is offered in several options among features such as selectable threshol d, hysteresis, timeouts, output types, etc. figure 1. application hookup 1. a resistor is required for open drain output type only. a 10 k pull-up is sufficient in most applications. 2. capacitor c ref is mandatory on v ref output (even if v ref is not used). capacitor value of 1 f is recommended. 3. for the stm6601 the processor has to confirm th e proper power-on during the fixed time period, t on_blank . this failsafe feature prevents the user from turning on the system when there is a faulty power switch or an unresponsive microprocessor. 6 7 0 6 7 0 3 % 2 8 7 9 5 ( ) 9 & |
