TP2011/TP2012/TP2014
Ultra-Low Power 200nA, 1.6V, RRIO, Push-Pull Output Comparators
Features
Descriptions
The TP201x family of push-pull output comparators
features the world-class lowest nano-power (250nA
maximum) and fast 13μs response time capability,
allowing operation from 1.6V to 5.5V. Input
common-mode range beyond supply rails makes the
TP201x an ideal choice for power-sensitive,
low-voltage (2-cell) applications.
The TP201x push-pull output supports rail-to-rail output
swing and interfaces with TTL /CMOS logic, and are
capable of driving heavy DC or capacitive loads. The
internal input hysteresis eliminates output switching
due to internal input noise voltage, reducing current
draw. The output limits supply current surges and
dynamic power consumption while switching. Beyond
the rails input and rail-to-rail output characteristics allow
the full power-supply voltage to be used for signal
range.
Micro-sized packages provide options for portable and
space-restricted applications. The single (TP2011) is
available in SC70-5, and the dual (TP2012) is available
in SOT23-8.
The related TP2015/6/8 family of comparators from
3PEAK has an open-drain output. Used with a pull-up
resistor, these devices can be used as level-shifters for
any desired voltage up to 10V and in wired-OR logic.

Pin Functions
N/C:
No Connection.
–IN:
Inverting Input of the Comparator. Voltage range of
this pin can go from V
–
– 0.3V to V
+
+ 0.3V.
+IN:
Non-Inverting Input of Comparator. This pin has the
same voltage range as –IN.
V+ (V
DD
):
Positive Power Supply. Typically the voltage is
from 1.6V to 5.5V. Split supplies are possible as long as
the voltage between V+ and V– is between 1.6V and
5.5V. A bypass capacitor of 0.1μF as close to the part as
possible should be used between power supply pins or
between supply pins and ground.
V
–
(V
SS
):
Negative Power Supply. It is normally tied
to ground. It can also be tied to a voltage other than
ground as long as the voltage between V
+
and V
–
is
from 1.6V to 5.5V. If it is not connected to ground,
bypass it with a capacitor of 0.1μF as close to the
part as possible.
OUT:
Comparator Output. The voltage range
extends to within millivolts of each supply rail.
LATCH:
Active
Low
Latch enable. Latch enable
threshold is 1/2V+ above negative supply rail.

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any
Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
Note 2:
The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power
supply, the input current should be limited to less than 10mA.
Note 3:
A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply
voltage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The
specified values are for short traces connected to the leads.
