TC650/TC651

Tiny Integrated Temperature Sensor & Brushless DC Fan

Controller with Overtemperature Alert

Features

General Description

• Integrated Temperature Sensing and Multi-speed

Fan Control

The TC650/TC651 are integrated temperature sensors

and brushless DC fan speed controllers. The TC650/

TC651 measure the junction temperature and control

the speed of the fan based on that temperature, making

them especially suited for applications in modern

electronic equipment.

• Built-in Overtemperature Alert (T_OVER

)

• Temperature-proportional Fan Speed Control for

Acoustic Noise Reduction and Longer Fan Life

• Pulse Width Modulation (PWM) Output Drive for

Cost and Power Savings

Temperature data is converted from the on-chip

thermal sensing element and translated into

a

• Solid-state Temperature Sensing

• ±1°C (typ.) Accuracy from 25°C to +70°C

• Operating Range: 2.8V – 5.5V

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

TC650/TC651 also include a single trip point over-

temperature alert (T_OVER) that eliminates the need for

additional temperature sensors. In addition, the TC651

features an auto fan shutdown function for additional

power savings.

• TC651 includes Automatic Fan Shutdown

• Low Operating Current: 50 µA (typ.)

Applications

• Thermal Protection For Personal Computers

• Digital Set-Top Boxes

• Notebook Computers

• Data Communications

• Power Supplies

The TC650/TC651 are easy to use, require no software

overhead and are, therefore, the ideal choice for

implementing thermal management in a variety of

systems.

Start-Up Timer

4.0

DETAILED DESCRIPTION

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 TC650/TC651 acquire and convert their junction

temperature (T_J) information from an on-chip, solid-

state sensor with a typical accuracy of ±1°C. The tem-

perature data is digitally stored in an internal register.

The register is compared with pre-defined threshold val-

ues. The six threshold values are equally distributed

over a pre-defined range of temperatures (see Table 4-

1). The TC650/TC651 control the speed of a DC brush-

less fan using a fractional speed-control scheme. The

output stage requires only a 2N2222-type, small-signal

BJT for fans up to 300 mA. 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

TC650/TC651 include an on-chip overtemperature

alarm (T_OVER) that gives a low signal when the temper-

ature of the chip exceeds T_Hby 10°C (typical). This fea-

ture eliminates the need for a separate temperature

sensor for overtemperature monitoring. Figure 4-1

shows the block diagram of the device.

4.3

Overtemperature Alert (T

)

OVER

This pin goes low when the T_Hset 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 air-

flow obstruction). This output may be treated as a

“System Overheat” warning and be used to either

trigger system shutdown or bring other fans in the

system to full speed. The fan will continue to run at full

speed while T_OVERis asserted. Built-in hysteresis

prevents T_OVERfrom “chattering” when the measured

temperature is at or near the T_H+ 10°C trip point. As

temperature falls through the T_H+ 10°C trip point, hys-

teresis maintains the T_OVERoutput low until the

measured temperature is 5°C above the trip point

setting.

Shutdown (SHDN)

PWM

The fan can be unconditionally shut down by pulling

the SHDN pin low. During shutdown, the PWM output

is low; ideal for notebook computers and other portable

applications where you need to change batteries and

must not have the fan running at that time. Thermal

monitoring and T_OVERare still in operation during

shutdown. I_DDshutdown current is around 50 µA.

Auto-shutdown Mode

FIGURE 4-1:

Functional Block Diagram.

The TC651 features auto-shutdown. When 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 equipment that

need to conserve as much battery power as possible

and, thus, run a fan when it is only absolutely needed.

The TC651 will continue to be active in order to monitor

temperature for T_OVER. The TC651 exits Auto-

shutdown mode when the temperature rises above the

factory set point (T₁).

4.1 PWM Output

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 15 Hz. The PWM is also the time base for the

Start-up Timer (see Section 4.2 “Start-Up Timer”).

The PWM duty cycle has a range of 40% to 100% for

the TC650 and 50% to 100% for the TC651.

DS21450C-page 7

TC650/TC651

Table 4-2 shows the device codes that specify the T_H

and T_Ltemperature thresholds. The following exam-

ples are given to assist in understanding the device-

ordering nomenclature.

4.6

Temperature Selection Guide

(Minimum Fan Speed/Full Speed)

There are two temperature thresholds that determine

the characteristics of the device. The minimum fan

speed temperature (T_L) and the full fan speed temper-

ature (T_H). Depending on the TC65X device selected,

when the temperature is below the T_Ltrip point, the

PWM output will perform a different operation. For the

TC650, the PWM will be driven at the minimum PWM

frequency, while the TC651 will shut down the PWM

(PWM = L).

Example 1: Suppose you wanted the fan to run at

40% speed at 25°C or less and go to full-

speed at 45°C. You would order the part

number TC650AEVUA.

Example 2: Suppose you wanted the fan to turn on at

30°C and go to full speed at 45°C. You

would order the part number

TC651BEVUA.

T_Land T_Hcan be selected in 5°C increments. T_Lcan

range from 25°C to 35°C. T_Hcan range from 35°C to

55°C and must be 10°C (or more) than the specified T_L.

THRESHOLDS

The five temperature regions defined by the six

thresholds are defined in the TC650/TC651 by means of

factory trimming. Once a T_Land T_Hare set, the T₁– T₄

TYPICAL APPLICATIONS

Reducing Switching Noise

For fans consuming more than 300 mA, a slowdown

capacitor (C_SLOW) is recommended for reducing

switching PWM induced noise (see Figure 5-1). The

value of this capacitor should be 4.7 µF to 47 µF,

depending on the fan current consumption.

See Application Note 771, “Suppressing Acoustic

Noise in PWM Fan Speed Control Systems”

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.

Information contained in this publication regarding device

applications and the like is intended through suggestion only

and may be superseded by updates. It is your responsibility to

ensure that your application meets with your specifications.

No representation or warranty is given and no liability is

assumed by Microchip Technology Incorporated with respect

to the accuracy or use of such information, or infringement of

patents or other intellectual property rights arising from such

use or otherwise. Use of Microchip’s products as critical

components in life support systems is not authorized except

with express written approval by Microchip. No licenses are

conveyed, implicitly or otherwise, under any intellectual
