Microcontroller supervisories
13 July 2005, DSP, Micros & Memory

Catalyst Semiconductor has expanded its supervisory product family of analog/mixed-signal ICs. The low power CAT1232LP and CAT1832 Watchdog Supervisors each perform three vital system functions - power on reset, software watchdog, and manual reset. The CAT1232LP is for 5 V systems, while the CAT1832 is for 3 V powered systems. The devices will hold a microprocessor/controller or system chipset in reset until the supply reaches the specified in-tolerance condition; and then maintains the reset condition for a minimum of 250 ms before releasing the reset so that the power supply has time to completely stabilise. A debounced manual reset input also allows the device to be connected to an external pushbutton, or other signal, for system restart. The ICs come in 8-lead SOIC, MSOP, DIP packages, consume 35 μA (CAT1232LP), 20 μA (CAT1832) and operate from -40 to +85°C.
