Texas Instruments TLV902x/TLV902x-Q1/TLV903x/TLV903x-Q1 Comparators
Texas Instruments TLV902x/TLV902x-Q1/TLV903x/TLV903x-Q1 Precision Comparators are a family of 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 100ns. These devices have an operating voltage range of 1.65V to 5.5V with a quiescent supply current of 18µA 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. A small amount of time passes before the output responds to the inputs. This feature prevents output transients during system power-up and power-down.
TThese comparators also feature no output phase inversion with fault-tolerant inputs that can go up to 6V without damage. This feature makes this family of comparators well-suited for precision voltage monitoring in harsh, noisy environments. The TLV902x/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/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 Texas Instruments TLV902x/TLV902x-Q1/TLV903x/TLV903x-Q1 are specified for the industrial temperature range of -40°C to +125°C and are available in standard leaded and leadless packages. The TLV902x-Q1/TLV903x-Q1 devices are AEC-Q100 qualified for automotive applications.
