User Programmable Micro-Power Voltage Detectors
General Description
The RT9801 is a micro-power voltage detector
supervising the power supply voltage level for
microprocessors (
μ
P) or digital systems. It provides
user programmable threshold levels with 0.1V step
ranging from 1.5V to 5V, which covers most digital
applications. It features low supply current of 3
μ
A.
Selection of V
TH
is easily achieved through 3 pins
connected to GND, VDD or floating for different
threshold voltage settings. Two versions of threshold
voltages, 1.5V ~ 4V and 2.5V ~ 5V, which are
programmed in factory are offered by customer
demands.
The RT9801 performs supervisory function by
sending out a reset signal whenever the VDD voltage
falls below a preset threshold level. This reset signal
will last the whole period before VDD recovering.
Reset signal will release after VDD is recovered and
lasts for the whole period of Reset Active Time-out
period.
RT9801 is N-channel, open-drain output and
provided in SOT-26 package.
