TC54
Voltage Detector
Features
General Description
• Precise Detection Thresholds: Standard ±2.0%,
Custom ±1.0%
The TC54 series are CMOS voltage detectors that are
especially well suited for battery-powered applications
because of their extremely low 1 µA operating current
and small surface-mount packaging. Each part is laser-
trimmed to the desired threshold voltage, which can be
specified from 1.4V to 7.7V for a 2% tolerance and from
1.5V to 6.0V for a 1% tolerance.
• Small Packages: 3-Pin SOT-23A, 3-Pin SOT-89,
TO-92 and 5-Pin SOT-23A (7.7V only)
• Low Current Drain: Typ. 1 µA
• Wide Detection Range: 1.1V to 6.0V and 7.7V
• Wide Operating Voltage Range: 0.7V to 10V
The device includes a comparator, low-current high-
precision reference, laser-trimmed divider, hysteresis
circuit and output driver. The TC54 is available with
either an open-drain or complementary output stage.
Applications
• Battery Voltage Monitoring
• Microprocessor Reset
During operation, the TC54's output (VOUT) remains in
the logic-high state as long as VIN is greater than the
• System Brown-Out Protection
• Switching Circuit in Battery Backup
• Level Discriminator
–
specified threshold voltage (VDET ). When VIN falls
–
below VDET , the output is driven to a logic-low. VOUT
–
remains low until VIN rises above VDET by an amount
VHYST, whereupon it resets to a logic-high.

The output (VOUT) will stay valid until the input voltage
falls below the minimum operating voltage (VINMIN) of
0.7V. Below this minimum operating voltage the output
is undefined. During power-up (or anytime VIN has
fallen below VINMIN), VOUT will remain undefined until
VIN rises above VINMIN. Once this occurs, the output
will become valid. VOUT will be in its active-low state,

DETAILED DESCRIPTION
–
,
In normal steady-state operation when VIN > VDET
the output will be at a logic-high (see Figure 3-1). In
the case of the TC54VN, this is an open-drain
–
condition. If the input falls below VDET , the output
will pull down (Logic 0) to VSS. Generally, VOUT can
pull down to within 0.5V of VSS at rated output current
and input voltage. (See Section 1.0 “Electrical
Characteristics”).
–
while VINMIN < VIN < VDET+ (therefore, VDET+ = VDET
+ VHYST). If the input rises above VDET+, the output will
assume its inactive state (high for TC54VC, open-drain
for TC54VN).

APPLICATIONS INFORMATION
Low operating power and small physical size make the
TC54 series ideal for many voltage detector applica-
tions, such as those shown in Figures 4-2, 4-3 and 4-4.
Figure 4-2 shows a low-voltage gate drive protection
circuit that prevents overheating of the logic-level
MOSFET due to insufficient gate voltage. When the
input signal is below the threshold of the TC54VN, its
output grounds the gate of the MOSFET. Figure 4-3 and
Figure 4-4 show the TC54 in conventional voltage
monitoring applications.
Modifying The Trip Point, V
–
DET
–
Although the TC54 has a pre-programmed VDET , it is
sometimes necessary to make adjustments during pro-
totyping. This can be accomplished by connecting an
external resistor divider to a TC54, which has a VDET
lower than that of VSOURCE (Figure 4-1).
–
To maintain detector accuracy, the bleeder current
through the divider should be significantly higher than
the 1 µA operating current required by the TC54. A
reasonable value for this bleeder current is 100 µA (100
times the 1 µA required by the TC54). For example, if
4.3V
–
VDET = 2V and the desired trip point is 2.5V, the value
270Ω
VCC
of R1 + R2 is 25 kΩ (2.5V/100 µA). The value of R1 + R2
can be rounded to the nearest standard value and
plugged into the equation of Figure 4-1 to calculate
values for R1 and R2. 1% tolerance resistors are
recommended.

2004 Microchip Technology Inc.
Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

applications and the like is intended through suggestion only
and may be superseded by updates. It is your responsibility to
