摘要：An insulated gate electrical load driving device includes simple and accurategate control circuitry for limiting load current therethrough. Preferably, all circuitry isformed of a single integrated circuit having the insulated gate load driving devicedielectrically isolated from the gate control circuitry. The gate control circuitry mayinclude either one, or both, of a zener diode and a resistor divider. An input drive signal tothe circuit is accurately controlled by the gate control circuitry to thereby limit thesaturation current through the insulated load driving device, and hence the load current,to predetermined current level. Preferably, the predetermined saturation current levelfalls within a range of saturation currents of the insulated gate load driving device that issubstantially constant over a wide operating temperature range.
