Applications
The SM72480SD-105/NOPB is designed for temperature monitoring and over-temperature protection in solar panel power optimizer and microinverter systems, where accurate thermal switching at 105°C is needed to protect electronics under high-irradiance conditions. Its ultra-low 16µA supply current makes it ideal for always-on thermal monitoring in energy-harvesting circuits that must preserve harvested power. It is also used in battery management systems for lithium-ion packs in solar storage applications, where accurate temperature thresholds must be maintained to prevent thermal runaway.

Frequently Asked Questions
What is the temperature trip point of the SM72480SD-105/NOPB?
The SM72480SD-105/NOPB is factory-set to a temperature switch trip point of 105°C, as indicated by the '-105' in the part number. When the die temperature exceeds this threshold, the output switches state to signal an over-temperature condition with a maximum accuracy of ±2.3°C.
What supply voltage does the SM72480SD-105/NOPB require?
The SM72480SD-105/NOPB operates at a supply voltage of 1.6V, making it compatible with low-voltage power management systems used in solar energy harvesting applications. Its ultra-low maximum operating current of 16µA minimizes the power drawn from the energy-harvesting circuit.
What is the SM72480SD-105/NOPB used for in solar applications?
The SM72480SD-105/NOPB is specifically designed as part of the Texas Instruments SolarMagic product family for temperature monitoring and protection in solar panel power optimizers, microinverters, and module-level power electronics (MLPE). It provides a simple threshold-based temperature switch output to trigger thermal shutdown or derating when solar panel electronics exceed 105°C.
What package does the SM72480SD-105/NOPB come in?
The SM72480SD-105/NOPB is housed in a 6-pin LLP (Leadless Lead-frame Package) measuring 2.5mm x 2.2mm x 0.8mm. This compact, low-profile surface-mount package minimizes board footprint and is suitable for fine-pitch PCB designs in space-constrained solar optimizer and energy-harvesting modules.
Does the SM72480SD-105/NOPB have short-circuit protection?
Yes, the SM72480SD-105/NOPB includes integrated short-circuit protection on the output pin, preventing damage to the device if the output is accidentally shorted to ground or the supply rail. This feature improves system reliability in outdoor and industrial solar installations where wiring faults may occur.
