The DS1819AR-10+T&R from Analog Devices (formerly Maxim Integrated) is a 3.3V MicroMonitor IC that provides essential monitoring for microprocessor systems. It monitors power supply status, software execution, and external override conditions.
This supervisor IC features a precision temperature-compensated reference and comparator circuit to detect out-of-tolerance power supply conditions. When VCC falls below a preset level, it generates an internal power-fail signal that forces the reset output to an active state. The reset signal is maintained for a minimum of 140ms after VCC returns to an in-tolerance condition, allowing the power supply and processor to stabilize.
The DS1819AR-10+T&R operates at a voltage of 2.925V and has an active low reset output. It is housed in a compact SOT-23-5 package, suitable for surface mount applications. The device operates within an industrial temperature range of -40°C to +85°C.
This component eliminates the need for discrete components in power monitoring and reset functions, offering a cost-effective solution for embedded systems requiring reliable microprocessor supervision.
