| TK610xx ADVANCED INFORMATION FEATURES s s s s s Very Low Quiescent Current ( 1 A) No External Components Built In Hysteresis (5% typ.) 2 % Voltage Detection Accuracy Miniature Package (SOT23-5) VOLTAGE DETECTOR APPLICATIONS s s s s s Battery Powered Systems Wireless Telephones Pagers Personal Communications Equipment Personal Digital Assistants DESCRIPTION The TK610xx family of voltage detectors is designed to provide accurate monitoring of the battery voltage. These low powered CMOS devices require no external components and are available in 0.1 V steps from 2.0 V to 5.0 V. When the input voltage reaches the detection voltage, the output goes low. This detection voltage has a 2 % accuracy and is set at the factory. When the input voltage goes high, the output will stay low until the voltage reaches the detection voltage plus hysteresis (+3 to +7 %). The TK610xx is available in a miniature SOT23-5 surface mount package. 01 S TK610xx OUT VDD GND NC NC BLOCK DIAGRAM VDD ORDERING INFORMATION TK610 Voltage Code S OUT Tape/Reel Code Vref VOLTAGE CODE * 23 = 2.3 V 25 = 2.5 V 27 = 2.7 V 30 = 3.0 V 33 = 3.3 V 36 = 3.6 V 40 = 4.0 V 41 = 4.1 V 42 = 4.2 V 45 = 4.5 V TAPE/REEL CODE TL: Tape Left GND * Consult factory for availability of other voltages October 1999 TOKO, Inc.

TK610xx DEFINITION AND EXPLANATION OF TECHNICAL TERMS DETECTION VOLTAGE (VDET) When VDD goes below the detection voltage, the output goes low. HYSTERESIS VOLTAGE (VHYS) When VDD goes above the sum of the detection voltage and the hysteresis voltage, the output goes high.

TK610xx APPLICATION INFORMATION CHANGING DETECTION VOLTAGE USING EXTERNAL RESISTORS It is not recommended to set the detection voltage using external resistors (See figure below) as oscillations may occur. VIN Note: For the TK610xx , there is an internal diode between GND and Output and another diode between Output and VDD. Current will flow between these terminals if the diodes are forward biased. See the figure below for diode polarity. VDD VDD VOUT GND OUT TK610XXS GND OUTPUT H CHARACTERISTICS FOR VDD < VDD1 The output voltage is not defined when VDD < VDDL.
