LM26LV

1.6 V, LLP-6 Factory Preset Temperature Switch and

Temperature Sensor

Automotive

■

General Description

Disk Drives

The LM26LV is a low-voltage, precision, dual-output, low-

Games

power temperature switch and temperature sensor. The tem-

perature trip point (T_TRIP) can be preset at the factory to any

temperature in the range of 0°C to 150°C in 1°C increments.

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

ble in an environment of temperature instability.

Appliances

Features

Low 1.6V operation

■

In normal operation the LM26LV temperature switch outputs

assert when the die temperature exceeds T_TRIP. The temper-

ature switch outputs will reset when the temperature falls

Low quiescent current

Push-pull and open-drain temperature switch outputs

Wide trip point range of 0°C to 150°C

below

a temperature equal to (T_TRIP− T_HYST). The

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

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

with an open-drain structure.

Very linear analog V_TEMPtemperature sensor output

V_TEMPoutput short-circuit protected

Accurate over −50°C to 150°C temperature range

An analog output, V_TEMP, delivers an analog output voltage

which is inversely proportional to the measured temperature.

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

Excellent power supply noise rejection

■

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 LM26LV'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 appli-

cations.
