TC642EV – Evaluation Kit for Brushless
DC Fan Controllers
DC Fan Controllers
The TC642EV is a complete evaluation kit for
evaluating and prototyping brushless DC fan control
circuits using Microchip’s TC642, TC646, TC647,
TC648 and TC649 BDC fan controllers. The fan speed
control signal can be provided by an external sensor or
voltage signal, or from the on-board potentiometer.
Minimum speed setting and auto-shutdown threshold
are conveniently set by a potentiometer. Jumper blocks
allow the user to quickly configure the output stage and
input signal source and scaling. Test points provide
easy access for instrument readings at critical nodes. A
user prototyping area is provided for dedicated circuitry
or other user specific circuits.

TC642DEMO – Fan Controller Demo Board for
TC642/646/647/648/649
TC642/646/647/648/649
This Fan Controller Demo Board allows the user to
quickly prototype fan control circuits based on
Microchip’s PWM fan control ICs (TC642, TC646,
TC647, TC648 or TC649). This 1.5" by 2.0" board’s
versatile sensor input and output driver circuitry allows
the Fan Controller Demo Board to be used with
virtually any brushless DC fan and standard thermistor.
An optional LED status indicator gives a visual
indication of a fan Fault condition (open stator, blocked
rotor or overtemperature Fault detection). It uses
through-hole components for easy user modification.

TC650DEMO – Fan Controller Demo Board for
TC650/651
TC650/651
This 1.0" x 1.0" Fan Controller Demo Board allows the
user to quickly prototype fan control circuits based on
Microchip’s TC650 or TC651 PWM Fan Control ICs.
The board can interface with virtually any brushless DC
fan. A red LED status indicator gives visual indication
of a fan Fault condition (open stator or blocked rotor)
and a green LED status indicator gives a visual
indication of an overtemperature alert (temperature is
10°C higher than the high temperature limit).

TC74DEMO – Serial Digital Temperature
Sensor Demo Board
Sensor Demo Board
The TC74DEMO Board allows the user to evaluate the
functionality of the tiny TC74 thermal sensor and
perform comparative evaluation against other thermal
management solutions. This 0.75" by 2.5" PC board is
an ideal solution for identifying the temperature profile
of applications like datacom, telecom and PC
equipment. The easy-to-use software provides a visual
representation of temperature profile and can interface
with any PC.
