3 Description

The TLV902xL and TLV903xL are a family of single and dual channel latching comparators. The family also offers low input offset voltage, power on reset (POR), and fault-tolerant rail-to-rail inputs. These devices have an excellent speed-to-power combination with a propagation delay of 110ns with a quiescent supply current of only 22μA per channel.

The unique feature of the TLV90xxL is the output latching capability. The output latches upon the first threshold crossing, allowing capture of an event or error condition without the full attention of a system controller. This feature allows events to be captured at start up while the system controller is still initializing or busy with other tasks. The falling-edge triggered clear input allows system controller to reset the latch after performing any needed tasks and meets safety-critical requirements. The L1 and L2 options define power-up latching behavior.

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

The TLV902xL have an open-drain output that can be pulled up below or beyond the supply voltage, designed for ORing multiple outputs or level translation. Latching occurs on the high to low output transition.

The TLV903xL have a push-pull output stage capable of sinking and sourcing up to 85mA to drive a capacitive load such as a MOSFET gate. Latching occurs on the low to high output transition.

The family is specified for the industrial temperature range of –40°C to +125°C and are available in standard leaded and leadless packages.
