1 RT9818 Micro-Power Voltage Detectors General Description The RT9818 is a micro-power voltage detector supervising the power supply voltage level for microprocessors (μp) or digital systems. It provides internally fixed threshold levels with.1v per step ranging from 1.V to V, which covers most digital applications. It features low supply current of μa. The RT9818 performs supervisory function by sending out a reset signal whenever the V DD voltage falls below a preset threshold level. This reset signal will last the whole period before V DD recovering. Once V DD recovered upcrossing the threshold level, the reset signal will be released after a certain delay time. RT9818 is provided in SC-8, SC-7-, SOT--, SOT-- and SOT-89 packages.

4 Note 1. Stresses beyond those listed Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions may affect device reliability. Note. θ JA is measured at T A = C on a low effective thermal conductivity single-layer test board per JEDEC 1-. Note. Note. Note. Devices are ESD sensitive. Handling precaution is recommended. The device is not guaranteed to function outside its operating conditions. The voltage V OL can be calculated by V OL = V DD Ir * R. Where R is the pull-up resistor and Ir is the current flowing through the pull-up resistor. For typical application (R=1kΩ), V OL is less than.v. Copyright 16 Richtek Technology Corporation. All rights reserved. DS August 16

9 Application Information Multiple Supplies Mainly, the pull-up connected to the RT9818 will connect to the supply voltage that is being monitored at the IC's pin. However, some systems may use the opendrain output to level-shift from the monitored supply to reset circuitry powered by some other supply. Benefits of Highly Accurate Reset Threshold Most μp supervisor ICs have reset threshold voltages between 1% and 1.% below the value of nominal supply voltages. This ensures a reset will not occur within 1% of the nominal supply, but will occur when the supply is 1.% below nominal. Copyright 16 Richtek Technology Corporation. All rights reserved.
