GENERAL DESCRIPTION
The NE1619 is designed for monitoring the temperatures and supply voltages of microprocessor-based systems by measuring those parameters and comparing the readings with programmable limits. The device provides five possible analog inputs, a remote temperature sensor input and on-board local temperature sensor. The device also monitors its own power supply and provides digital inputs for the Pentium/PRO power supply ID code.

FEATURES
• Monitor local and remote temperatures
• Temperature accuracy of ±2 °C for local, and ±3 °C for remote channel
• Temperature resolution of 1 °C
• 2.8 V to 5.5 V supply range
• Monitor different power supplies: 12 V, 5 V, 3.3 V, 2.5 V, VCCP, VDD
• VIN accuracy of ±2% of full scale
• Differential non-linearity of ±1LSB
• No calibration required
• Programmable temperature and voltage limits for alarms
• Programmable Reset low state pulse output
• SMBus 2-wire serial interface
• Small 16-lead SSOP (QSOP) package
• Compatible with Intel “Heceta 4” specification and reference designs utilizing it
• ESD protection exceeds 2000 V HBM per JESD22-A114, 250 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
• Latch-up testing is done to JESDEC Standard JESD78 which exceeds 100 mA

APPLICATIONS
• System thermal and hardware monitor
• Desktop computers
• Notebook computers
• Industrial controllers
• Telecom equipment
