DESCRIPTION

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 +3V to +26V supply,

drawing a maximum of 1.4mA of supply current, and

they are specified for operation from –40°C to

+125°C.
