MC642
PWM Fan Speed Controller
with Fault Detection
The MC642 is a pulse width modulation (PWM) fan speed
controller for use with DC motors. It provides temperature
proportional speed control. A thermistor connected to the V
IN
input
furnishes the required control voltage of 1.25V to 2.65V for 0% to
100% PWM duty cycle. Minimum fan speed is set by a simple resistor
divider on the V
MIN
input. An integrated Start–Up Timer ensures
reliable motor start–up at turn–on, coming out of Shutdown Mode, or
following a transient fault. A stalled, open, or unconnected fan causes
the MC642 to trigger its start–up timer
once.
If the fault persists, the
FAULT output goes low, and the device is latched in Shutdown Mode.
Features
Shutdown Mode for Power Saving
Supports Low Cost NTC/PTC Thermistors
Temperature Proportional Speed for Acoustic Control /
Longer Fan Life
Fan Voltage Independent of MC642 Supply Voltage
Fault Detection Circuits Protect Against Fan Failure and
Aid System Testing
Operating Temperature Range: 0°C to +85°C
Typical Applications
Power Supplies
Personal Computers
UPS’s, Power Amplifiers, etc.

Does anyone have the matrix keyboard driver for ep9315? I have a problem with the keyboard driver. Thank you.
My keyboard driver does not have row scanning, no matter which interface the row is connected to, it will show the key of one interface. So only one row of key values can be printed. Thank you everyon...
