Does anyone know of an IC that functions like a watchdog timer only with an output that stays low until it is reset rather that pulsing low?

WD timers usually present one state at the occurrence of pulses and will go high or low when alarm out, is this what you need?

Thank you SailorJoe. I have looked through several spec sheets on watchdog timers and have only found ones that pulse low, i.e. send a uC reset signal, rather than just stay low. Basically, I am looking to send a signal to the master controller that this uC has locked up.
