TLV9034-Q1数据手册TI中文资料规格书

描述 Description

The TLV902x -Q1 and TLV903x -Q1 are a family of Automotive grade dual and quad channel comparators. The family offers low input offset voltage, integrated Power-On Reset (POR) circuitry, and fault-tolerant inputs with an excellent speed-to-power combination with a propagation delay of 100 ns. Operating voltage range of 1.65 V to 5.5 V with a quiescent supply current of 18 µA per channel.

This device family also includes a Power-on Reset (POR) feature that ensures the output is in a known state until the minimum supply voltage has been reached and a small time period passed before the output starts responding to the inputs. This prevents output transients during system power-up and power-down.

These comparators also feature no output phase inversion with fault-tolerant inputs that can go up to 6-V without damage. This makes this family of comparators well suited for precision voltage monitoring in harsh, noisy environments.

The TLV902x -Q1 comparators have an open-drain output stage that can be pulled below or beyond the supply voltage, making it appropriate for low voltage logic and level translators.

The TLV903x -Q1 comparators have a push-pull output stage capable of sinking and sourcing milliamps of current when controlling an LED or driving a capacitive load such as a MOSFET gate.

The TLV902x -Q1 and TLV903x -Q1 are specified for the Automotive temperature range of -40°C to +125°C and are available in a standard leaded and leadless packages.
