HTC KOREA DS1232D
The DS1232 Micro-Monitor monitors three vital conditions for a microprocessor: power supply, software execution, and external override. When an out–of–tolerance condition occurs, an internal power fail signal is generated which forces reset to the active state. When VCC returns to an in–tolerance condition, the reset signals are kept in the active state for a minimum of 250ms to allow the power supply and processor to stabilize.| Part No. | DS1232D |

DESCRIPTION
First, a precision temperature compensated reference and comparator circuit monitors the status of VCC. The second function the DS1232 performs is pushbutton reset control. The DS1232 debounces the pushbutton input and guarantees an active reset pulse width of 250ms minimum. The third function is a watchdog timer. The DS1232 has an internal timer that forces the reset signals to the active state if the strobe input is not driven low prior to time–out. The watchdog timer function can be set to operate on time–out settings of approximately 150ms, 600ms, and 1.2 seconds.
