MAX6615AEE+T

MAX6615AEE+T is a dual-channel temperature monitor and fan-speed controller with thermistor inputs. The temperature data controls a PWM output signal to adjust the speed of a cooling fan, thereby minimizing noise when the system is running cool, but providing maximum cooling when power dissipation increases. The 2-wire serial interface accepts standard system management bus (SMBus™) write byte, read byte, send byte, and receive byte commands to read the temperature data and program the alarm thresholds. The programmable alarm output can be used to generate interrupts, throttle signals, or overtemperature shutdown signals. Applications include desktop computers, servers, power supplies, networking equipment, and workstations.

• Two thermistor inputs, two open-drain PWM outputs for fan-speed control
• Local temperature sensor
• Programmable fan-control characteristics
• Controlled PWM rate-of-change ensures unobtrusive fan-speed adjustments
• Fail-safe system protection, active-low OT output for throttling or shutdown
• Nine different pin-programmable SMBus addresses
• Operating supply voltage range from 3.0 to 5.5V
• Standby current is 10µA max at interface inactive, ADC in idle state
• 16 QSOP package
• Temperature range from -40°C to +125°C
