The TLV1805-Q1 high voltage comparator offers the unique combination 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-suited for applications that require sensing at the positive or negative voltage rails such as reverse current protection for a smart diode controller, overcurrent sensing, and overvoltage protection circuits where the push-pull output stage is used to drive the gate of a p-channel or n-channel MOSFET switch.

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

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