The TLV3501A-Q1 push-pull output comparator features a fast 4.5-ns propagation delay and operation from 2.7 V to 5.5 V. The input voltage supports a common-mode range that goes beyond the rails which makes the device an ideal choice for low-voltage applications. The rail-to-rail output directly drives either CMOS or TTL logic. The fast delay and wide common-mode range also makes TLV3501A-Q1 device ideal for EMI reduction through frequency dithering by lowering the EMI peaks. These parameters allow the device to be ideal for both DC-DC converter and inverter applications in HEV/EV and powertrain.

The SOT23-6 microsized package provides options for portable and space-restricted applications. The Z-suffix offers reduced delamination compared to the standard device.
