The EMC1422-1-ACZL-TR from Microchip Technology is a high-accuracy, low-cost System Management Bus (SMBus) temperature sensor. It monitors two temperature channels, one external and one internal, with ±1°C accuracy for external diodes and ±2°C for the internal diode. Advanced features include Resistance Error Correction (REC) and Beta Compensation, which support various CPU thermal diode models including 45nm, 65nm, and 90nm processors. The sensor also provides automatic diode type detection, freeing users from complex configuration.
This device offers a hardware programmable system shutdown feature that can be configured via pull-up resistor values and cannot be masked or corrupted through the SMBus. The operating temperature range is -40°C to 125°C, with a local sensing range of -40°C to 125°C and a remote sensing range of -64°C to 191°C. The output type is SMBus, and it operates on a supply voltage of 3V to 3.6V. The resolution is 11 bits.
The EMC1422-1-ACZL-TR is available in a compact 8-MSOP package, suitable for surface mount applications. Its features include an output switch, programmable limit, and shutdown mode, making it a flexible solution for critical temperature monitoring in applications such as notebook computers, desktop computers, industrial systems, and embedded applications.
