초록

An insulated gate electrical load driving device includes simple and accurate gate control circuitry for limiting load current therethrough. Preferably, all circuitry is formed of a single integrated circuit having the insulated gate load driving device dielectrically isolated from the gate control circuitry. The gate control circuitry may include either one, or both, of a zener diode and a resistor divider. An input drive signal to the circuit is accurately controlled by the gate control circuitry to thereby limit the saturation current through the insu...
