FEATURES
Measures Two Remote Temperatures No Calibration Required SMBus 2-Wire Serial Interface Programmable Under/Over-temperature Alarms Programmable Thermal Shutdown Signal Supports SMBus Alert Response Accuracy: ±5°C (-40°C to + 125°C, remote) ±3°C (+60°C to + 100°C, remote) +4.5V to +5.5V Supply Range Fan speed control range: 3,000 to 30,000 rpm Fan speed accuracy: ±2% Built-in MOSFET switch Internal current-limit and over-temperature protection for fan control Watchdog for fan control Alarm for fan failure Precision Monitoring of 5V Power-Supply Voltage 340ms Typical Power-On Reset Pulse Width RESET Output Guaranteed RESET Valid to VCC=1V Power Supply Transient Immunity No External Components needed for reset function Small, 16-Pin SSOP Package G768D GENERAL DESCRIPTION
Except for one less fan controller, G768D is backward compatible with G768B. G768D has 2 more functions, fan-failure detection and programmable thermal shutdown signal. Remote accuracy is ±5°C for multiple transistor manufacturers, with no calibration needed.
