Overview
The TLV1805DBVR, produced by Texas Instruments, is a high-voltage comparator that offers a unique combination of features making it versatile for a wide range of applications. It operates within a supply voltage range of 3.3 V to 40 V, making it suitable for various high-voltage systems. The device features a push-pull output, rail-to-rail inputs with phase reversal protection, and a low quiescent current of 135 µA. Additionally, it includes built-in hysteresis, a propagation delay of 250 ns, and a low input offset voltage of 500 µV. The TLV1805DBVR also includes a shutdown feature with high-z output and a Power-On Reset (POR) to prevent false outputs at power-up. It is packaged in a 6-pin SOT-23 (DBV) package and is specified for operation across the extended industrial temperature range of –40°C to +125°C.
