TMP512 and TMP513 are temperature and power supply system monitors that include remote sensors, a local temperature sensor, and a high-side current shunt monitor. These system monitors have the capability of measuring remote temperatures, on-chip temperatures, and system voltage/power/current consumption.
The TMP512 (dual‑channel) and TMP513 (triple‑channel) system monitors provide remote temperature sensing, on‑chip temperature measurement, and high‑side current shunt monitoring. They support SMBus/two‑wire communication, include watchdog limits, and report voltage, current, and power.
Typical operating specifications include a supply range of 3 V to 26 V, 12‑bit ADC resolution, 1.4 mA quiescent current, and an operating temperature range of –40 °C to +125 °C. The devices are offered in 14‑lead SOIC and 16‑lead QFN packages with detailed pin configurations for sensor connections, GPIO, and alert output.
| Supply Voltage Range | 3 V to 26 V |
|---|---|
| ADC Resolution | 12 bits |
| Current Sense Gain Error | +0.04 % |
| Quiescent Current | 1.4 mA |
| Operating Temperature Range | –40 °C to +125 °C |
The devices operate from 3 V up to 26 V.
Both devices have a 12‑bit analog‑to‑digital converter.
The TMP512 provides two temperature‑sensor channels (dual‑channel).
The devices use a two‑wire SMBus compatible serial interface.
