DS1816R-20+T&R

The DS1816R-20+T&R is a 3.3V EconoReset monitor with open drain output in 3 pin SOT-23 package. A precision temperature compensated reference and comparator circuit is used to monitor the status of the power supply (VCC). It provides a function of detecting out of tolerance power supply conditions and warning a processor based system of impending power failure. When VCC is detected in out of tolerance condition, an internal power fail signal is generated which forces reset to the active state. When VCC returns to an intolerance condition, the reset signal is kept in the active state for approximately 150ms to allow the power supply and processor to stabilize.

• Supply voltage range is 0V to 5.5V
• Operating temperature range from -40°C to 85°C
• Vcc trip point is 2.55V
• Automatically restarts microprocessor after power failure
• Reduces need for discrete components
• Accurate 20% tolerance of power monitoring
• Output capacitance is 10pF
• Efficient open drain output with internal 5Kohm pull-up resistor
• Output current is 10mA at 0.4V
• Operating current is 28µA at VCC <lt/> 5.5V
