Abstract
A liquid discharge head substrate is provided. The liquid discharge head substrate includes a discharge unit including a discharge element configured to generate energy for discharging a liquid from an orifice and a discharge control circuit configured to control the discharge element, and a first voltage generation circuit configured to supply, to the discharge control circuit, a first driving voltage for driving the discharge control circuit. The discharge unit includes a first node having a voltage correlated with a voltage to be supplied to the discharge element. The first voltage generation circuit controls the first driving voltage based on a comparison result of the voltage of the first node and a first reference voltage supplied from outside of the liquid discharge head substrate.
