DESCRIPTION

· The ADM1033 is a one-channel remote and local temperature sensor with fan speed control.

· It monitors the temperature of a remote thermal diode and its own ambient temperature.

· The device can control fan speed based on a programmable target or a temperature-to-fan speed profile.

· It supports SMBus 2.0, 1.1, and 1.0 communication interfaces.

FEATURES

· Local and remote temperature channels with ±1°C accuracy.

· Fast temperature measurements up to 64 per second.

· Programmable over/undertemperature limits and fault queue.

· SMBus ALERT output and fail-safe overtemperature comparator.

· Fan speed control with linear and discrete options via look-up table.

· THERM input for timing PROCHOT assertions and REF input as reference.

· Operates with a 3.0 V to 5.5 V supply in a 16-lead QSOP package.

APPLICATIONS

· Desktop and notebook PCs.

· Embedded systems.

· Telecommunications equipment.

· LCD projectors.
