DS1232 Description

Short technical summary and product information.

The DS1232 MicroMonitor chip from Texas Instruments is a dedicated supervisor IC for microprocessor systems. It monitors three vital conditions: power supply status, software execution, and external override.

 

The device features a precision temperature-compensated reference and comparator circuit to monitor the VCC power supply. It detects out-of-tolerance conditions and generates reset signals to halt the microprocessor. When VCC returns to an in-tolerance condition, reset signals are maintained for a minimum of 250 ms to allow for system stabilization.

 

Additionally, the DS1232 provides pushbutton reset control with debouncing and guarantees an active reset pulse width of 250 ms minimum. It also incorporates a watchdog timer that forces reset signals active if a strobe input is not driven low before timeout. The watchdog timer can be configured for timeout settings of approximately 150 ms, 600 ms, and 1.2 seconds.

 

The DS1232 is available in space-saving 8-pin mini-DIP and optional 16-pin SOIC surface mount packages. It operates within an industrial temperature range of -40°C to +85°C.
