The TLV1805-Q1 high voltage comparator offers the uniquecombination of wide supply range, push-pull output, rail-to-rail inputs, low quiescent current,shutdown capability and fast output response. All these features make this comparator well-suitedfor applications that require sensing at the positive or negative voltage rails such as reversecurrent protection for a smart diode controller, overcurrent sensing, and overvoltage protectioncircuits where the push-pull output stage is used to drive the gate of a p-channel or n-channelMOSFET switch.

The high peak current push-pull output stage, which is unique for high-voltagecomparators, offers the advantage of allowing the output to actively drive the load to eithersupply rail with a fast edge rate. This is especially valuable in applications where a MOSFET gateneeds to be driven high or low quickly in order to connect or disconnect a host from an unexpectedhigh voltage supply. Additional features such as low input offset voltage, low input bias currentsand High-Z shutdown make the TLV1805-Q1 flexible enough to handle abroad range of applications. Power-On reset prevents false outputs at power-up.

The TLV1805-Q1 is AEC-Q100 qualifiedin a 6-pin SOT-23 package and is specified for operation across the automotive Grade 1 temperature range of –40°C to +125°C.
