General Description
The TC652/TC653 are integrated temperature sensors
and brushless DC fan speed controllers with
FanSense™ technology. The TC652/TC653 measure
their junction temperature and control the speed of the
fan based on that temperature, making them especially
suited for applications in modern electronic equipment.
The FanSense™ Fan Fault detect circuitry eliminates
the need for a more expensive 3-wire fan.
• TC653 includes Auto Fan Shutdown
• Low Operating Current: 50µA (Typical)
Applications
• Thermal Protection For Personal Computers
• Digital Set-Top Boxes
• Notebook Computers
• Data Communications
• Power Supplies
Temperature data is converted from the on-chip
thermal sensing element and translated into
fractional fan speed from 40% to 100%. A temperature
selection guide in the data sheet is used to choose the
low and high temperature limits to control the fan. The
TC652/TC653 also include a single trip point over

additional temperature sensors. In addition, the TC653
includes an auto fan shutdown function for additional
power savings.
• Application Note: AN771
Device Selection Table
The TC652/TC653 are easy to use, require no software
overhead and are therefore the ideal choice for
implementing thermal management in a variety of
systems.

DETAILED DESCRIPTION
The TC652/TC653 acquire and convert their junction
temperature (T ) information from an on-chip solid
J
state sensor with a typical accuracy of ±1°C. The
temperature data is digitally stored in an internal
register. The register is compared with pre-defined
threshold values. The six threshold values are equally
distributed over a pre-defined range of temperatures
(See Table 3-1 and Table 3-2). The TC652/TC653
control the speed of a DC brushless fan using a
fractional speed control scheme. The output stage
requires only a 2N2222-type small-signal BJT for fans
up to 300mA. For larger current fans (up to 1 Amp) a
logic-level N-channel MOSFET may be used. In
addition to controlling the speed of the fan, the TC652/
TC653 include an on-chip over-temperature alarm

The PWM pin is designed to drive a low cost transistor
or MOSFET as the low side power switching element in
the system. This output has an asymmetric
complementary drive and is optimized for driving NPN
transistors or N-channel MOSFETs. Since the system
relies on PWM rather than linear power control, the
dissipation in the power switch is kept to a minimum.
Generally, very small devices (TO-92 or SOT
packages) will suffice. The frequency of the PWM is
about 15Hz. The PWM is also the time base for the
Start-up Timer (see paragraphs below). The PWM duty
cycle has a range of 40% to 100% for the TC652 and
50% to 100% for the TC653.

Shutdown (SHDN)
To ensure reliable fan start-up, the Start-up Timer turns
PWM high for about 2 seconds whenever the fan is
started from the off state. This occurs at power-up and
when coming out of Shutdown mode.
The fan can be unconditionally shutdown by pulling low
the SHDN pin. During shutdown, FAULT output is high
and PWM output is low. This is ideal for notebook
computers and other portable applications when you
need to change batteries and must not have the fan

DD
is around 50µA.
The SENSE input, Pin 5, is connected to a low value
current sensing resistor in the ground return leg of the
fan circuit through the capacitor. During normal fan
operation, commutation occurs as each pole of the fan
is energized. This causes brief interruptions in the fan
current, seen as pulses across the sense resistor. If the
device is not in Shutdown mode, and pulses are not
appearing at the SENSE input, a FAULT exists. The
short, rapid change in fan current (high di/dt) causes a

Auto-Shutdown Mode
The TC653 has auto-shutdown. If the temperature is
below the factory set point at minimum speed (T ),
L
PWM is low and the fan is automatically shut off (Auto-
shutdown mode). This feature is ideal for notebook
computers and other portable applications that need to
conserve as much battery power as possible and thus
run a fan when it is only absolutely needed. The TC653
will continue to be active so as to monitor temperature
corresponding dv/dt across the sense resistor, R
.

Over-Temperature Alert (TOVER)
This pin goes low when the T set point is exceeded

by 10°C (typical). This indicates that the fan is at
maximum drive, and the potential exists for system
overheating: either heat dissipation in the system has
gone beyond the cooling system's design limits, or
some FAULT exists such as fan bearing failure or an
airflow obstruction. This output may be treated as a
“System Overheat” warning and used to trigger system
shutdown, or bring other fans to full speed in the
system. The fan will continue to run at 100% speed
