The LM26LV and LM26LV-Q1 are low-voltage, precision, dual-output, low-power temperature switches and temperature sensors. The temperature trip point (TTRIP) 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 (THYST) keeps the output stable in an environment of temperature instability.

In normal operation the LM26LV or LM26LV-Q1 temperature switch outputs assert when the die temperature exceeds TTRIP. The temperature switch outputs will reset when the temperature falls below a temperature equal to (TTRIP – THYST). 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.

The analog output, VTEMP, delivers an analog output voltage with Negative Temperature Coefficient (NTC).

Driving the TRIP_TEST input high causes the digital outputs to be asserted for in-situ verification and causes the threshold voltage to appear at the VTEMP output pin, which could be used to verify the temperature trip point.

The LM26LV’s and LM26LV-Q1’s low minimum supply voltage makes them ideal for 1.8-V system designs. The wide operating range, low supply current, and excellent accuracy provide a temperature switch solution for a wide range of commercial and industrial applications.

參考設計

PMP22396 — 適合汽車應用的 2460-W 雙向升壓轉換器參考設計

此參考設計為適合汽車應用的 2460-W 雙向升壓轉換器。電路由額定 12-V 電池供電，在 51.25 A 時提供 48 V 的輸出電壓。此設計使用兩個雙相同步雙向控制器，以每相位 200 kHz 的切換頻率運作。48-V 輸出設計用於驅動馬達。當負載電流反向且輸出電壓達 54 V 時，磁滯方向控制可讓負載電流返回至 12-V 電池。當輸出電壓回到 48 V 時，便會恢復正常升壓運作。MOSFET 下方的底側散熱片會設有安裝孔。
