TS331CX5 RFG

P1-P3P4-P5
TS331
Low Power Low Offset Voltage Comparators
1/5 Version: B14
SOT-25
General Description
The TS331 is single precision voltage comparators capable of single-supply or split-supply operation. The
specifications as low as 2.0 mV make this device an excellent ground level with single-supply operation. Input
offset-voltage selection for many applications in consumer automotive, and It is designed to permit a common
mode range-to- industrial electronics.

Note 1. The max. Output current may be as high as 20mA, independent of the magnitude of V
CC
, output short
circuits to V
CC
can cause excessive heating and eventual destruction.
Note 2. This magnitude of input current will only occur if the input leads are driven more negative than ground or
the negative supply voltage. This is due to the input PNP collector base junction becoming forward biased
acting as an input clamp diode. There is also a lateral PNP parasitic transistor action on the IC chip. This
phenomena can cause the output voltage of the comparators to go to the V
CC
voltage level (or ground if
overdrive is large) during the time the input is driven negative. This will not destroy the device and normal
output states will recover when the inputs become -0.3V of ground or negative supply.
Note 3. At output switch point, V

CC
from 5Vdc to 30Vdc, and over the full input common-
mode
Note 4. Due to the PNP transistor inputs, bias current will flow out of the inputs, this current is essentially constant
independent of the output state, therefore, no loading changes will exist on the input lines.
Note 5. Input common mode of either input should not be permitted to go more than 0.3V negative of ground or
minus supply. The upper limit of common mode range is V
CC
- 1.5V but either or both inputs can betaken
to as high as 30volts without damage.
Note 6. Response time is specified with a 100mV step and 5.0mV of overdrive. With larger magnitudes of
overdrive faster response times are obtainable.
Application information
This comparator feature high gain, wide bandwidth characteristics. This gives the device oscillation tendencies if
the outputs are capacitive coupled to the inputs via stray capacitance. This oscillation manifests itself during
output transitions (V
OL
to V
OH
). To alleviate this situation input resistors<10KΩ should be used. The addition of
positive feedback (<10 mV) is also recommended.
It is good design practice to ground all unused pins. Differential input voltages may be larger than supply voltage
without damaging the comparator's inputs. Voltages more negative than -0.3V should not be used.
