Voltage detector offers adjustable watchdog timer
With a built in adjustable watchdog timer, Torex Semiconductor's XC6130/31 voltage detector is suited for high reliability applications where the system needs to be able to recover from code errors without human intervention. The reset timeout and the watchdog timeout period can be adjusted using an external capacitor while a separate manual reset input on the XC6130 allows a simple push button interface.
The XC6131 series has a watchdog ON/OFF function, which allows the watchdog function to be turned OFF while the voltage detector that monitors the power voltage continues to operate. With a revised internal circuit which offers improved Temperature Characteristics (±50ppm/degC), higher detector treshold accuracy (±1.0% at 25˚C) and low power consumption (9.8µA), the XC6130/31 is ideally suited for monitoring a wide range of microprocessors, in all types of battery powered applications.
The XC6130/31 comes with an N-channel open drain output and is configured as Detect Low (RESETB). The Detect Voltage Range can be set between 1.6V and 5.0V in 0.1V steps. The XC6130/31 is available in the SOT-26 package and is fully RoHS compliant and Halogen free.
