1 / 6 page TS803 Microprocessor Reset Circuit 1/6 Version: A07 SOT-23 General Description The TS803/TS803R are microprocessor (µP) supervisory circuit used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V powered circuits. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The TS803/TS803R are open –drain outputs. The TS803/TS803R have an active low RESET output, while the TS803/TS803R has an active high RESET output. The reset comparator is designed to ignore fast transients on VCC, and the output guaranteed to be in the correct logic state for VCC down to 1V. Low supply correct makes the TS803/TS803R ideal for use in portable equipment. Features ● Precision monitoring of +3V, +3.3V & +5V power supply voltage ● Fully specified over temperature ● Available in three output configurations ● Open-Drain RESET low output ● 3uA supply current ● Guaranteed reset valid to Vcc = +1V ● Power supply transient immunity ● No external components Applications ● Computers ● Controllers ● Intelligent Instruments ● Critical uP and uC power monitoring ● Portable / Battery Power Equipment ● Automotive Ordering Information Note: x is the threshold voltage type, option as TS803 Threshold Voltage A : 4.63V B : 4.38V C : 4.00V D : 3.08V E : 2.93V F : 2.63V G : 2.32V H : 2.1V I : 2.0V J : 1.8V K :1.6V TS803R Threshold Voltage B : 4.20V E : 2.93V F : 2.70V Contact factory for additional voltage options.
