    • An integrated circuit (IC) includes a logic circuit (320) monolithically formed on the IC. The logic circuit is configured to generate modulation signals (330a, 330b, 330c; 332a, 332b, 332c) for controlling power switches of a power inverter. The logic circuit (320) generates the modulation signals based on at least one input value (idx1, idx2, idx3). The IC further includes a voltage level shifter (334a, 334b, 334c) monolithically formed on the IC. The voltage level shifter is configured to shift the modulation signals to a voltage level suitable for driving the power switches of the power inverter. The logic circuit can be a digital logic circuit and the input value can be a digital input value. The IC can also include a sense circuit (322) monolithically formed on the IC. The sense circuit is configured to generate the input value (idx2).
