3.3V MicroMonitorチップ

入手可能：生産中

The DS1832 3.3-volt MicroMonitor Chip is pin-compatible with the industry-standard DS1232 and operates in both 3.0- and 3.3-volt environments. Like the DS1232, the DS1832 monitors power supply, software execution, and an external pushbutton override. It is designed with CMOS outputs and is capable of maintaining a valid output on the active low reset to 0 volts with a 100kΩ pull-down resistor. On power-up, the DS1832 holds reset for 250ms to allow the system to stabilize.

Moving a design from 5 volts to 3.3 volts can be as simple as substituting the DS1832 for the DS1232 and removing the pull-up resistor on the active low reset. This makes it a versatile, space- and cost-saving monitor for any processor-driven system requiring reliable operation.
