DS1232LP+ by Analog Devices

Low-Power MicroMonitor Chip

Status: Active
Series: DS1232LP
RoHS: Unknown
View Datasheet Manufacturer Site View Pricing & Stock

The DS1232LP/LPS Low-Power MicroMonitor Chip monitors three vital conditions for a microprocessor: power supply, software execution, and external override. First, a precision temperature-compensated reference and comparator circuit monitors the status of VCC. 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.
