| UNISONIC TECHNOLOGIES CO., LTD TS391/A/B/C LOW POWER SINGLE VOLTAGE COMPARATOR DESCRIPTION The UTC TS391/A/B/C consist of a low power voltage comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. This comparator also has a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage. LINEAR INTEGRATED CIRCUIT FEATURES * Wide single supply voltage range or dual supplies +2V ~ *+34V or 1V ~ 18V * Very low supply current (0.2mA) independent of supply voltage (1mW /comparator at +5V) * Low input bias current: 25nA typ. * Low input offset current: 5nA typ. * Low input offset voltage: 1mV typ * Input common-mode voltage range includes ground. * Low output saturation voltage: 250mV typ.(IOUT=4mA). * Differential input voltage range equal to the supply *voltage. *Pb-free plating product number: TS391L/TS391AL/TS391BL/TS391CL ORDERING INFORMATION Order Number Normal Lead Free Plating TS391-AF5-R TS391L-AF5-R TS391A-AF5-R TS391AL-AF5-R TS391B-AF5-R TS391BL-AF5-R TS391C-AF5-R TS391CL-AF5-R TS391-AL5-R TS391L-AL5-R TS391A-AL5-R TS391AL-AL5-R TS391B-AL5-R TS391BL-AL5-R TS391C-AL5-R TS391CL-AL5-R Package SOT-25 SOT-25 SOT-25 SOT-25 SOT-353 SOT-353 SOT-353 SOT-353 Packing Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel Tape Reel TS391L-AF5-R (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel (2) AF5: SOT-25 (3) L: Lead Free Plating, Blank: Pb/Sn www.unisonic.com.tw Copyright (c) 2005 Unisonic Technologies Co., Ltd 1 of 6 QW-R104-003,C TS391/A/B/C MARKING LINEAR INTEGRATED CIRCUIT PIN CONNECTIONS (top view) TS391 IN(-) 3 GND 2 Output 1 IN(-) 3 TS391A GND 2 IN(+) 1 4 IN(+) 5 Vcc 4 Output 5 Vcc TS391B IN(+) 3 GND 2 Output 1 TS391C + - 4 IN(-) 5 Vcc UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R104-003,C TS391/A/B/C BLOCK DIAGRAM Vcc+ LINEAR INTEGRATED CIRCUIT 3.5A 100A 3.5A 100A IN(+) GND IN(-) GND Output GND UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 6 QW-R104-003,C TS391/A/B/C ABSOLUTE MAXIMUM RATINGS LINEAR INTEGRATED CIRCUIT PARAMETER SYMBOL RATING UNIT Supply Voltage VCC 18 or 36 V Differential Input Voltage VI(DIFF) 36 V Input Voltage VIN -0.3 ~ +36 V Output Short-Circuit to Ground 1) Infinite Power Dissipation PD 500 mW Junction Temperature TJ 150 C Operating Temperature TOPR -40 ~ +125 C -65 ~ +150 Storage Temperature TSTG C Note 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. Short-circuit from the output to VCC can cause excessive heating and eventual destruction. The maximum output current is approximately 20mA, independent of the magnitude of VCC.

At output switch point, Vo=1.4V, Rs=0 with VCC from 5V ~ 30V and over the full input common-mode range(0V ~ VCC 1.5V). 2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference or input lines. 3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V.The upper end of the common-mode voltage range is VCC + -1.5V,but either or both inputs can go to +30V without damage. 4. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range the comparator will provide a proper output state. The low input voltage state must not be less than -0.3V (or 0.3V below the negative power supply, if used). 5. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained.
