ADT7488AARMZ-RL

Thermal Management Overview

The ADT7488A is a digital temperature sensor and voltage monitor featuring a Simple Serial Transport (SST) interface. It includes one on-chip local temperature sensor and supports two remote diode inputs. The device monitors three voltage channels: VCC, VCCP, and a 2.5V supply. It operates within a supply voltage range of 3.0 V to 3.6 V. Local sensor accuracy is ±1.0°C from -40°C to +70°C. Remote sensor accuracy reaches ±1.0°C at 25°C ambient. The component utilizes a 10-lead MSOP package.

Thermal Management Feature Summary
