SM72480

SolarMagic 1.6V, LLP-6 Factory Preset Temperature Switch

and Temperature Sensor

General Description

Features

The SM72480 is a low-voltage, precision, dual-output, low-

power temperature switch and temperature sensor. The tem-

perature trip point (T_TRIP) is set at the factory to be 120°C.

Built-in temperature hysteresis (T_HYST) keeps the output sta-

ble in an environment of temperature instability.

Renewable Energy Grade

■

Low 1.6V operation

Latching function: device can latch the Over Temperature

condition

Push-pull and open-drain temperature switch outputs

■

In normal operation the SM72480 temperature switch outputs

assert when the die temperature exceeds T_TRIP. The temper-

ature switch outputs will reset when the temperature falls

a temperature equal to (T_TRIP− T_HYST). The

2.2 mm by 2.5 mm (typ) LLP-6 package

OVERTEMP digital output, is active-high with a push-pull

structure, while the OVERTEMP digital output, is active-low

with an open-drain structure.

Excellent power supply noise rejection

■

Key Specifications

The analog output, V_TEMP, delivers an analog output voltage

with Negative Temperature Coefficient — NTC.

■ Accuracy, Trip Point

Temperature

Driving the TRIP TEST input high: (1) causes the digital out-

puts to be asserted for in-situ verification and, (2) causes the

threshold voltage to appear at the V_TEMPoutput pin, which

could be used to verify the temperature trip point.

The SM72480's low minimum supply voltage makes it ideal

for 1.8 volt system designs. Its wide operating range, low

supply current , and excellent accuracy provide a temperature

switch solution for a wide range of commercial and industrial

applications.
