    • A die for a thermal drop-on-demand fluid-ejection device includes thermal firing resistors, low-side switches, and high-side switches. The thermal firing resistors are organized over resistor groups such that each thermal firing resistor is located within only one of the resistor groups. The resistor groups are lesser in number than the thermal firing resistors. Each thermal firing resistor has a first end and a second end. The low-side switches are equal in number to the thermal firing resistors. Each low-side switch connects the second end of a corresponding thermal firing resistor to a low voltage. The high-side switches are equal in number to the resistor groups. Each high-side switch connects the first ends of the thermal firing resistors of a corresponding resistor group to power providing a voltage greater than the low voltage.
    • 用于热滴式流体喷射装置的模具包括热激发电阻器,低侧开关和高侧开关。 热触发电阻器组织在电阻器组上,使得每个热激发电阻器仅位于电阻器组之中。 电阻组的数量比热激发电阻小。 每个热激电阻器具有第一端和第二端。 低边开关的数量与热激发电阻的数量相等。 每个低侧开关将相应的热激发电阻器的第二端连接到低电压。 高边开关的数量与电阻组数量相等。 每个高侧开关将相应电阻器组的热激发电阻器的第一端连接到提供大于低电压的电压的功率。
