Texas Instruments' TLV1805 high-voltage comparator offers a unique combination of a wide supply range, push-pull output, rail to rail input, low quiescent current, closing capability, and fast output response. TLV1805 is packaged in a 6-pin SOT-23 package and is applicable to the extended industrial temperature range from - 40 ° C to+125 ° C. These characteristics make it more suitable for applications that need to use positive or negative voltage sensing rails, such as the reverse current protection controller of smart diodes, over-current sensing, push-pull output stage and over-voltage protection circuits to drive p-channel or n-channel MOSFET switches at the door.
High peak current push-pull output stage, which is the unique feature of the high-voltage comparator, provides the advantage of allowing the output to actively drive the load to any supply rail at a fast edge rate. This is very valuable in applications where it is necessary to drive the MOSFET gate up or down quickly to connect or disconnect the host and the unexpected high-voltage power supply. TLV1805 device has the characteristics of low input bias voltage, low input bias current and high z turn off, which makes it flexible enough to handle a wide range of applications. Power on reset (POR) prevents error output during power on.
