The TLC3702 consists of two independent micropower voltage comparators designed to operate from a single supply and be compatible with modern HCMOS logic systems. They are functionally similar to the LM339 but use one-twentieth of the power for similar response times. The push-pull CMOS output stage drives capacitive loads directly without a power-consuming pullup resistor to achieve the stated response time. Eliminating the pullup resistor not only reduces power dissipation, but also saves board space and component cost. The output stage is also fully compatible with TTL requirements.

Texas Instruments LinCMOS™ process offers superior analog performance to standard CMOS processes. Along with the standard CMOS advantages of low power without sacrificing speed, high input impedance, and low bias currents, the LinCMOS™ process offers extremely stable input offset voltages with large differential input voltages. This characteristic makes it possible to build reliable CMOS comparators.

The TLC3702C is characterized for operation over the commercial temperature range of 0°C to 70°C. The TLC3702I is characterized for operation over the extended industrial temperature range of –40°C to 85°C. The TLC3702M is characterized for operation over the full military temperature range of –55°C to 125°C.

CIRCUIT060079 — 具有比較器電路的過電壓保護

此過電壓防護電路使用含推挽輸出級的高電壓比較器,控制將電源連接至負載的 P 通道 MOSFET。當供應電壓超過過電壓閾值 (VOVER) 時,比較器的輸出會變高,並開啟 P 通道 MOSFET 斷開電源的負載。同樣的,當供應電壓低於 VOVER 時,比較器的輸出為 LOW,並將負載連接至 SUPPLY。
