MAX6663AEE+

MAX6663AEE+ is a temperature monitor and PWM fan controller. It is an ACPI-compliant local and remote-junction temperature sensor and fan controller. This device measures its own die temperature, as well as the temperature of a remote PN junction and controls the speed of a DC cooling fan based on the measured temperature. Internal watchdog set points are provided for both local and remote temperatures. There are two comparison set points for local temperatures and two for remote temperatures. When a set point is crossed, this asserts either the active-low INT or active-low THERM outputs. These outputs can be used as interrupts, clock throttle signals, or overtemperature shutdown signals. Applications include personal computers, servers, workstations, telecom equipment, networking equipment, test equipment, and industrial controls.

• Remote-junction temperature sensor within ±1°C accuracy (+60°C to +100°C)

• 0.125°C resolution local and remote-junction temperature measurement
• Programmable temperature offset for system calibration
• SMBus 2-wire serial interface with timeout, controlled PWM rise/fall times
• PWM fan control output, fan-speed monitoring and watchdog
• Fan fault and failure indicators, +3V to +5.5V supply range
• Operating current is 0.5mA typ at SMBDAT=SMBCLK=1, VCC=+3.3V, TA=+25°C
• 16 QSOP package
• Temperature range from -40°C to +125°C
