TS391, TS391A Datasheet Low-power single voltage comparator Features • • SOT23-5 DFN8 2x2 • • • • • Wide single supply voltage range or dual supplies 2 V to 36 V or ± 1 V to ± 18 V Very low supply current (0.2 mA) independent of supply voltage (1 mW / comparator at 5 V) Low input bias current: 25 nA typ. Low input offset current: ± 5 nA typ. Low input offset voltage: ± 2 mV max. for TS391A Input common-mode voltage range includes ground Low output saturation voltage: 250 mV typ. (Io= 4 mA) • • Differential input voltage range equal to the supply voltage TTL, DTL, ECL, CMOS compatible outputs Description These devices 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. These comparators also have a unique characteristic where the input common-mode voltage range includes ground, even though operated from a single power supply voltage.

Output voltage can be set up to 36 V even if the VCC is lower. 2. Short-circuits from the output to VCC + can cause excessive heating and potential destruction. The maximum output current is approximately 20 mA independent of the magnitude of VCC +. 3. Short-circuits can cause excessive heating. These values are typical. 4. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 5. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating. 6. Charged device model: all pins and package are charged together to the specified voltage and then discharged directly to ground through only one pin. This is done for all pins. Table 2.

The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage range is (VCC +) – 1.5 V, but either or both inputs can go to 30 V without damage.

At the output switch point, Vo ≈ 1.4 V, RS = 0 Ω with (VCC +) from 5 V to 30 V, and over the full input common-mode range (0 V to (VCC +) – 1.5 V). 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 there is no load charge on the reference of input lines. 3. Positive excursions of the 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 –0.3 V (or 0.3 V below the negative power supply, if used) 4. The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals, 300 ns can be obtained. DS1551 - Rev 10 page 5/16 TS391, TS391A Electrical characteristic curves 5 Electrical characteristic curves Figure 4.
