产品概述
The DS1819CR-10+T&R is a 3.3V MicroMonitor in 5 pin SOT-23 package. This device monitors three vital conditions for microprocessor such as power supply, software execution and external override. 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 forces reset to active state. The reset signal is kept in active state for a minimum of 140ms to allow the power supply and processor to stabilize when VCC returns to an in tolerance condition. The DS1819C performs pushbutton reset control. It debounces the pushbutton input and generates an active reset pulse width of 140ms minimum. It is pin and function compatible with MAX823/24/25 devices.
- Supply voltage range from 1V to 5.5V
- Operating temperature range from -40°C to 85°C
- Halts and restarts an out of control microprocessor
- Holds microprocessor in check during power transients
- Automatically restarts microprocessor after power failure
- Monitors pushbutton for external override
- Eliminates the need for discrete components
- VCC trip point is 3V and reset active time is 200ms
- Accurate 10% microprocessor power monitoring and operating current of 8μA
- Active-high, push-pull and active-low, push-pull reset output
