1. than several us V 5 Please use N ch open drains configuration when a resistor Rin is connected between the Vn pin and power source In such cases please ensure that Ry is less than kQ and that C is more than 0 1uF D TS61Nxx Ir Diagram Circuit using an input resistor Oscillation Description OUTPUT CURRENT OSCILLATION WITH THE CMOS OUTPUT CONFIGURATION When the voltage applied at IN rises release operations commence and the detector s output voltage increases Load current lour will flow at RL Because a voltage drop Rin X lour is produced at the R resistor located between the input IN and the Vn pin the load current will flow via the IC s Vn pin The voltage drop will also lead to a fall in the voltage level at the Vn pin When the Vin pin voltage level falls below the detec voltage level detect operations will commence Following detect operations load current flow will cease and since voltage drop at Rn will disappear the voltage level at the Vyn pin will rise and release operations will begin over again Oscillation may occur with this release detect release repetition Further this condition will also appear via means of a similar mechanism during detect operations Rn X lour Voltage Drop Diagram 1 Oscillation in relation to output current A 7 Version A07 s5 E TS61 Series 65 RoHS Voltage Detector COMPLIANCE Oscillation Description Continue OUTPUT CURRENT OSCILLATION WI2. 6 0V 2 for Standard Voltage Detectors Release Voltage Vpr Vpr Vuys 2 7 Version A07 s5 E TS61 Series fs RoHS Voltage Detector COMPLIANCE Typical Application Circuit CMOS Output N Channel Open Drain Output Measuring Circuit Test Circuit 1 Test Circuit 2 Test Circuit 3 Vin Vout D TS61Cxx Gnd Tae ue TS61Cxx Gnd Vin Gnd Not Necessary with CMOS output product Test Circuit 4 Test Circuit 5 measurement of waveform TS61Nxx Gnd eo Not Necessary with CMOS output products 3 7 Version AO7 TS61 Series Pb ROHS Voltage Detector COMPLIANCE Directions for use 1 Please use this IC within the stated maximum ratings Operation beyond these limits may cause degrading or permanent damage to the device 2 When a resistor is connected between the Vn pin and the input CMOS output configurations oscillation may occur as a result of voltage drops at Rin if load current lour exists refer to the Oscillation Description below 3 When a resisted is connected between the Vix pin and the input with CMOS output configurations irrespective of N ch output configurations oscillation may occur as a result of through current at the time of voltage release even if load current lout does not exist refer to the Oscillation Description below 4 In order to stabilize the IC s operations please ensure that Vin pin s input frequency s rise and fall times are more

4. TH THE CMOS OUTPUT CONFIGURATION Since the TS61 series are CMOS ICs through current will flow when the IC s internal circuit switching operates during release and detect operations Consequently oscillation is liable to occur as a result of drops in voltage at the through current s resistor R during release voltage operations refer to diagram 2 Since hysteresis exists during detect operation oscillation is unlikely to occur V JRun ts6inex Rw X lour Voltage Drop Diagram 2 Oscillation in relation to through current Function Description 1 When input voltage Vn rises above detect voltage Vpf output voltage Vout will be equal to V A condition of high impedance exists with N ch open drain output configurations 2 When input voltage Vn falls below detect voltage VpF output voltage will be equal to the ground voltage Vss 3 When input voltage Vin falls to a level below that of the minimum operating voltage Vyin output will become unstable In this condition Vij will equal the pulled up output should output be pull up 4 When input voltage Vin rises above the ground voltage Vss level output will be unstable at levels below the minimum operating voltage Vmin Between the Vun and detect release voltage Vpr level the ground voltage Vss level will be maintained 5 When input voltage Vin rises above detect release voltage Vpr output voltage Vout will be equal to Vin A condition of high im
