The TMP512 (dual-channel) and TMP513 (triple-channel) are 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 remote temperature sensor diode-connected transistors are typically low-cost, NPN- or PNP-type transistors or diodes that are an integral part of microcontrollers, microprocessors, or FPGAs. Remote accuracy is ±1°C for multiple IC manufacturers, with no calibration needed. The two-wire serial interface accepts SMBus™ or two-wire write and read commands.

The onboard current shunt monitor is a high-side current shunt and power monitor. It monitors both the shunt drop and supply voltage. A programmable calibration value (along with the TMP512/TMP513 internal digital multiplier) enables direct readout in amps; an additional multiplication calculates power in watts. The TMP512 and TMP513 both feature two separate onboard watchdog capabilities: an over-limit comparator and a lower-limit comparator.

These devices use a single +3 V to +26 V supply, drawing a maximum of 1.4 mA of supply current, and they are specified for operation from –40°C to +125°C.
