The RT9819C-30GV is a MicroPower Voltage Detector with CMOS push-pull output. The voltage detector supervising the power supply voltage level for microprocessors (μP) or digital systems. It provides internally fixed threshold levels with 0.1V per step ranging from 1.2 to 5V, which covers most digital applications. It features low supply current of 3μA. The RT9819 performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a preset threshold level. This reset signal will lasts the whole period before VDD recovering. Once VDD recovered upcrossing the threshold level, the reset signal will be released after a certain delay time.

• No external components required
• Quick reset within 20μs
• ±1.5% High accuracy
• 3μA Low supply current
• 0.9V Low functional supply voltage
