EMC1422 - Temperature Sensor

General Description

The EMC1422 is a high-accuracy, low-cost, System Management Bus (SMBus) temperature sensor.

Key Features

  • Hardware Thermal Shutdown - Triggers dedicated SYS_SHDN pin - Hardware configured range +77°C to +112°C in +1°C steps - Cannot be disabled or modified by software.
  • Support for diodes requiring the BJT/transistor model - Supports 45 nm, 65 nm and 90 nm CPU thermal diodes.
  • Pin compatible with ADM1032, MAX6649 and LM99.
  • Automatically determines external diode type and optimal settings.
  • Resistance Error Correction.
  • External Temperature Monitors.
