LM79CCVF

The LM79CCVF is one member of the LM79 family which is designed as the microprocessor system hardware monitor that can be used in (1)system hardware monitoring for servers and PCs; (2)office Electronics; (3)electronic Test Equipment and Instrumentation. Also this device has an on-chip temperature sensor, 5 positive analog inputs, two inverting inputs (for monitoring negative voltages), and an 8-bit ADC. An input is provided for the overtemperature outputs of additional temperature sensors and this is linked to the interrupt system.

Features of the LM79CCVF are:(1)temperature sensing; (2)5 positive voltage inputs; (3)2 op amps for negative voltage monitoring; (4)3 fan speed monitoring inputs; (5)input for additional temperature sensors; (6)chassis Intrusion Detector input; (7)WATCHDOG comparison of all monitored values; (8)POST code storage RAM. And the key specifications of this device are:(1)voltage monitoring accuracy ±1% (max); (2)temperature accuracy 10°C to +100°C ±3°C (max); (3)supply voltage 5V; (4)supply current operating: 1 mA typ and shutdown: 10 A typ; (5)ADC resolution 8 bits.

The absolute maximum ratings of the LM79CCVF can be summarized as:(1)positive supply voltage (Vcc):6.5 V;(2)voltage on any input or output pin: -0.3V to (Vcc+0.3V);(3)ground difference (GNDDGNDA): ±300 mV;(4)input current at any pin:±5 mA;(5)package input current:±20 mA;(6)maximum junction temperature:150°C;(7)ESD susceptibility human body model:2000 V;(8)ESD susceptibility machine model:175 V;(9)storage temperature:-65°C to +150°C.
